Description
Technical field
The present invention relates to oil well completion technical field, specifically a kind of integrated flow string of oil-extracting and water-injecting.
Background technology
At present, injection-production well requires early stage electric submersible pumping, later stage water filling；Water injection well early stage electric submersible pump discharge opeing, later stage water filling,
And it is conventional at present using Y-shaped electric submersible pump producing tubular column, its tubing string needs steel wire operation when by recovering the oil or discharge opeing carries out metaideophone water
Branch pipe blanking plug is picked up, causes field operation amount and operating cost increase；Marine some jacket platforms do not possess steel wire operation
Condition, steel wire operation need to rearrange drilling platforms, and the activity duration increases with cost by huge.
Existing many offshore oilfield production casings are 7 ", are limited by wellbore space, it is impossible to use conventional Y-shaped electric submersible pump pipe
Post；Special Y-shaped tubing string is parallel due to its electric submersible pump unit and bypass line, bypass branch pipe diameter and electric submersible pump unit it is straight
Footpath selection needs balance, and the tubing string of this structure type limits the selection of the latent pump assembly of large-discharge electric of larger diameter size,
Water filling is also limit simultaneously and bypasses the selection of manifold size, is recovered the oil or discharge opeing, huge discharge water filling it is difficult to meet huge discharge simultaneously
It is required that.
It is conventional " Y " type electric submersible pump producing tubular columns, during metaideophone, steel wire operation pulling bypass branch pipe plug need to be carried out, and steel
Silk Job Operations are limited by hole deviation, and conventional Y-piece post can not also meet steel wire metaideophone job requirements in high angle hole.
The content of the invention
In order to overcome above-mentioned deficiency, operated it is an object of the invention to provide a kind of simplified metaideophone, shorten the activity duration,
Reduce the integrated flow string of changeable oil-extracting and water-injecting of operating cost.
In order to solve the above technical problems, the technical solution adopted in the present invention is：
A kind of integrated flow string of changeable oil-extracting and water-injecting, including well inner sleeve, the oil pipe in well inner sleeve, it is arranged on oil
The storm valve for being connected with liquid controling pipe line on pipe top, the electric submersible pump for being connected with cable for being arranged on oil pipe bottom, the oil
It is provided between pipe and well inner sleeve and positioned at the lower section of storm valve on packer, the oil pipe and positioned at the lower section of packer
Seating nipple and runner conversion pipe nipple are sequentially provided with, the runner conversion pipe nipple includes check valve and near valve, when export-oriented oily from well
In pipe during water filling, under hydraulic pressure, closed check valve, near valve is opened, and the water in injection oil pipe is through near valve access wall inner sleeve
In, when electric submersible pump starts oil recovery or the draining to outside well, under oil pressure or hydraulic pressure, check valve is opened, and near valve is closed, well inner sleeve
Oil or water in pipe enter in oil pipe through electric submersible pump and check valve and discharged upwards outside well through oil pipe.
Further, it is provided with the vent valve for being connected with liquid controling pipe line on the packer.
The beneficial effects of the present invention are：
（1）The present invention is mounted with that runner changes pipe nipple, and changing pipe nipple by multi-functional runner coordinates the operation of start and stop pump to realize production
With the free switching of waterflood path.By oil recovery metaideophone water when only need termination of pumping, operation step is poly- simple, without carrying out steel wire work
Industry, shortens the activity duration, reduces operating cost.
（2）The present invention is applied to the pit shaft of 7 " production casings, and electric submersible pump unit and oil pipe selection size selection scope are wide, energy
Huge discharge is met simultaneously to recover the oil or discharge opeing, the requirement of huge discharge water filling.
（3）The operation that the present invention turns water-filling function by oil recovery can meet high angle hole oil-extracting and water-injecting one not by Well Deflection Influence
The requirement of body tubing string.
（4）The present invention production packer be provided with vent valve, with multi-functional runner conversion pipe nipple coordinate, without deblocking or
Steel wire operation, so that it may realize direct circulation or reacting cycle kill-job, can effectively shorten activity duration, reduction operating cost.
