In step S20, after carrying out direct circulation, steel ball 204 is put into out of described trombone slide 302, and continue release of fetching water, The size of the steel ball 204 matches with the diameter for setting step 202a, so that steel ball 204 is being seated in setting on step 202a Afterwards, circulatory flow can be blocked.Therefore, the pressure fluid injected above oil pipe 301 will be from the first bindiny mechanism and the The toroidal cavity formed between two bindiny mechanisms enters, hydraulic to be passed to outside oil pipe 301 by 301 inner space of oil pipe, final to make With to 202 top surface of setting ball seat, 203 top surface of hanging pup joint and set cone 201 bottom surface on.Act on 202 top surface of setting ball seat, The pressure of 203 top surface of hanging pup joint can generate downward thrust, but since seal receptacle 103 is fixedly connected with 101 lower end of ontology, to Under thrust setting ball seat 202, hanging pup joint 203 can not be made to move down.And it acts on and sets the pressure for boring 201 bottom surfaces then Upward thrust can be generated, promotion sets cone 201 and runs up.Under the action of thrust, 201 extrusion bodies 101 of cone are set, when When thrust is greater than the yield limit of 101 material of ontology, ontology 101 will swell generation permanent deformation, swollen with ontology 101 Greatly, the sealing ring 102 set on section 101a outer wall is caused to be compressed tightly against between ontology 101 and sleeve A.When setting cone 201 When releasing from 101 top of ontology, pressure drops to zero suddenly, and packer setting is completed.Ontology 101 sets section 101a's at this time Internal diameter is identical as extension diameter section 101c internal diameter, and changeover portion 101b disappears, and the sealing ring 102 being extruded plays the dual of sealing and suspension Effect, such as Fig. 3, Fig. 4.
In step s 30, when set cone 201 drive oil pipes 301 play out preset distance after, above mention oil pipe 301, set cone 201 will rise out with oil pipe 301, set the internal diameter of cone 201 because the outer diameter of 302 upper end of trombone slide is greater than, therefore setting cone 201 can be with Trombone slide 302 and the setting ball seat 202 being connected to below trombone slide 302 rise out together, and setting ball seat 202 passes through the first locking member Hanging pup joint 203 is inconjunction with and rises out together by 401, the packer after setting and seal receptacle 103 is left behind in well, such as Fig. 3 institute Show.
In step s 40, as shown in Fig. 2, Fig. 5 and Fig. 7, after packer setting, after tripping in flow string carries out in well Continuous oil producing operation.Specifically, being connected with oil well pump 6 on the flow string, can be connected with below the oil well pump 6 outstanding Pipe nipple 203 is hung, the lower end of hanging pup joint 203 has been connected through a screw thread gas anchor 7, the attachmentes such as 8 are blocked up at bottom.Tripping in is connected with above-mentioned attachment Flow string when, the outer limited step 103b on hanging pup joint 203 is seated in the first limited step on seal receptacle 103 103a。
Flow string after being seated in will not drive packer living even if having slight wriggling, activity in oil producing operation It is dynamic, so as to avoid the factor for causing packer to fail because of friction between sealing ring 102 and sleeve A.Flow string tripping in Afterwards, water-yielding stratum is separated by the sealing between packer and sleeve A, hanging pup joint 203 and seal receptacle 103, and the oil of oil reservoir then passes through Gas anchor 7 enters to oil well pump 6 and is extracted.
It should be noted that in the present embodiment, the oil well pump 6, which also can according to need, is connected to hanging pup joint 203 Lower section, the submergence of increasing pump, to improve pump efficiency.
In another embodiment, the second locking member is provided between the hanging pup joint 203 and the seal receptacle 103 402, the third groove for accommodating second locking member 402 is provided on the outer wall of the hanging pup joint 203.Described second The locking force of locking member 402 is greater than first locking member 401.
Second locking member 402 is specially big circlip, and the big circlip is the elastic metallic ring of an opening, and section is in " interior flat evagination " shape.Although large and small circlip section configuration is identical, cross-sectional area, evagination bevel angle, internal-and external diameter size are respectively not It is identical, by being adjusted to above-mentioned parameter, the circlip of different locking forces can be designed.When installation, the big circlip peace It is filled in the third groove, the lower end of hanging pup joint 203 is arranged in the third groove.When being seated in the hanging pup joint 203, Big circlip can be caught in the lower end of seal receptacle 103 and flick, and evagination inclined-plane can be resisted against the lower end of seal receptacle 103.By It is greater than first locking member 401 in the locking force of the second locking member 402, therefore even if the first locking member is installed at the same time 401 and second under conditions of locking member 402, can guarantee that setting ball seat 202, can only be from the first lock when acting the process upwards Shake off at tight part 401, without taking hanging pup joint 203 out of together.
It should be noted that if hanging pup joint 203 has not needed out, the first locking member 401 of installation can not had to, thus anti- Hanging pup joint 203 is carry when only setting ball seat 202 rises out and is risen out together, the second locking member 402 is only installed at this time.If The needs of hanging pup joint 203 rise out together with setting ball seat 202, then cannot install the second locking member 402, only install the first locking member 401。
In the present embodiment, described when being equipped with the second locking member 402 between hanging pup joint 203 and seal receptacle 103 The lower end of hanging pup joint 203 is fixedly connected with the first flow string.
Specifically, packer is assembled first, referring to figs. 1 to shown in Fig. 6.Installation sets cone 201 in ontology 101, makes it The conical surface lean against on changeover portion 101b.Setting ball seat 202 is mounted in hanging pup joint 203 again, is seated in the second limited step On 203a, the first locking member 401 can be installed, and can also not have to installation.Preferably, the first locking member 401 is not installed.Setting ball After seat 202 is installed in extension diameter section 101c together with hanging pup joint 203, then seal receptacle 103 is installed.In hanging pup joint 203 Second locking member 402 is installed in third groove.The oil pumping attachment such as 8, gas anchor 7 successively first is blocked up at bottom according to projected depth to go into the well, so Hanging pup joint 203 is attached with the first flow string gone into the well afterwards, the lower end setting of the hanging pup joint 203 is useful In the screw thread of connection.Oil pipe 301 is passed through inside ontology 101 finally, 201 is connect with cone is set, then by trombone slide 302 from oil It passes through in pipe 301, is connect with setting ball seat 303.
In the present embodiment, present invention also provides it is a kind of using it is described every adopt packer every adopting construction method, it is described Include: every adopting construction method
S10: the pressure fluid of predetermined amount is injected out of described oil pipe 301;
S20: putting into steel ball 204 out of described trombone slide 302, continues injection pressure liquid and the steel ball 204 is seated in described In setting ball seat 202;
S30: after the oil pipe 301 rises out to preset distance, the oil pipe 301 is above mentioned, the oil pipe 301 drives described Cone 201, the trombone slide 302, the setting ball seat 202 is set to rise out together;
S40: the bottom of second flow string is connected into insertion pipe 501, tripping in is connected with the institute of the insertion pipe 501 The second flow string is stated, until the insertion pipe 501 is inserted into the hanging pup joint 203.
Specifically, in step slo, progress direct circulation first is injected into oil pipe 301 and the connection tubing string of top The pressure fluid of predetermined amount, in the present embodiment, the predetermined amount of pressure fluid are specially that the above pit shaft of depth locating for packer holds Product.The circulatory flow that pressure fluid is successively formed through trombone slide 302, setting ball seat 202 circulates, and reaches setting ball seat 202 and suspension Then the bottom of pipe nipple 203 is returned out by the annular space formed between sleeve A and packer to well head again.
In step S20, after carrying out direct circulation, steel ball 204 is put into out of described trombone slide 302, and continue release of fetching water, The size of the steel ball 204 matches with the diameter for setting step 202a, so that steel ball 204 is being seated in setting on step 202a Afterwards, circulatory flow can be blocked.Therefore, the pressure fluid injected above oil pipe 301 will be from the first bindiny mechanism and the The toroidal cavity formed between two bindiny mechanisms enters, hydraulic to be passed to outside oil pipe 301 by 301 inner space of oil pipe, final to make With to 202 top surface of setting ball seat, 203 top surface of hanging pup joint and set cone 201 bottom surface on.Act on 202 top surface of setting ball seat, The pressure of 203 top surface of hanging pup joint can generate downward thrust, and because seal receptacle 103 is fixed on the lower end of ontology 101, downward is pushed away Power can not be such that setting ball seat 202, hanging pup joint 203 moves down.Act on set cone 201 bottom surfaces pressure can generate upwards Thrust, promotion sets cone and 201 runs up.Under the action of thrust, 201 extrusion bodies 101 of cone are set, when thrust is greater than this When the yield limit of 101 material of body, ontology 101, which will swell, generates permanent deformation, with swelling for ontology 101, causes to set Sealing ring 102 on section 101a outer wall is compressed tightly against between ontology 101 and sleeve A.It is pushed up when setting cone 201 from ontology 101 When end is released, pressure drops to zero suddenly, and packer setting is completed.At this time the internal diameter for setting section 101a of ontology 101 with it is expanding Section 101c internal diameter is identical, and changeover portion 101b disappears, and the sealing ring 102 being extruded plays a dual role of sealing and suspension, such as schemes 3, Fig. 4.
In step s 30, when set cone 201 drive oil pipes 301 play out preset distance after, above mention oil pipe 301, set cone 201 will rise out with oil pipe 301, set the internal diameter of cone 201 because the outer diameter of 302 upper end of trombone slide is greater than, therefore setting cone 201 can be with Trombone slide 302 and the setting ball seat 202 being connected to below trombone slide 302 rise out together, and hanging pup joint 203 is because by the second lock The locking effect of tight part 402 has not had, and the first flow string still stays in well thereunder for hanging pup joint 203 and connection Under.
In step s 40, after packer setting, the second flow string of tripping in.Specifically, on second flow string It is connected with oil well pump 6, connects insertion pipe 501 in 6 or less oil well pump.It is using the second flow string that oil well pump 6 is lower deep to design After degree, insertion pipe 501 is inserted into hanging pup joint 203.Second flow string and first flow string pass through described Insertion pipe 501 and hanging pup joint 203 are docked, and complete oil pumping flow string is formed.At this time water-yielding stratum by every adopt packing Sealing between the ontology 101 of device and oil well casing A, hanging pup joint 203 and packer, insertion pipe 501 and hanging pup joint 203 every It opens, the oil of oil reservoir then enters oil well pump 6 and be extracted by gas anchor 7.
