Description

Bore the rotation outlet device of radial water flat hole guider
Technical field
The invention belongs to oil, coal, natural gas technical field, particularly a kind of continuous pipe bores the well of radial water flat hole Lower apparatus for work, specifically a kind of rotation outlet device for boring radial water flat hole guider.
Background technology
At present at home and abroad in oilfield exploitation industry, continuous pipe bores radial water flat hole technology and is mainly used in that Oil/gas Well is secondary to be opened Hair, there is notable effect of increasing production to low-permeability oil deposit transformation, the band pollution layer transformation of nearly well.
Existing continuous pipe bores radial water flat hole technology and mainly transfers positioning and guiding instrument first with conventional tubing string To the layer position of pre- operation, then, drill bushing piping tool is transferred in positioning and guiding instrument using continuous pipe, carries out cased bore-bole work Industry, after the completion of drilling, with continuously drill bushing piping tool has been managed out, then, jet drilling formation tool is transferred to using continuous pipe and determined In the steering tool of position, jet drilling stratum operation is carried out, after brill stratum operation terminates, is played jet drilling formation tool with continuous pipe Go out, finally, with conventional tubing string by positioning and guiding instrument from pit shaft go out, so as to complete entirely to bore radial water flat hole operation work Sequence.
As shown in figure 1, positioning and guiding kit recited above contains a locator 11 and a guider 12, wherein fixed Position device 11 is used for the positioning by power tool in work layer, and guider 12 then bores for guide bur sleeve tool 13 on sleeve pipe Hole windowing task, and jet drilling formation tool are crept into the earth formation.Wherein, the drill bushing piping tool 13 is driven by screw motor 14 It is dynamic, and in the internal rotation of S-shaped passage 16 of guider 12, progress cased bore-bole operation, due to drill bushing piping tool 13 and S-shaped passage 16 Between gap delta be present, from centrifugal action principle, when drill bushing piping tool 13 is in S-shaped 16 internal rotation of passage, it can be in S Larger eccentric wear resistance is produced on the inwall of shape passage 16, the eccentric wear resistance can produce two negative effects to boring procedure:One It is effective drilling torque when can weaken drill bushing 13 drill sleeve of piping tool, so as to cause bit freezing;Second, drill bushing piping tool 13 and S-shaped The inwall of passage 16 can wear, and be further exacerbated by gap delta therebetween, cause eccentric wear resistance to become big, aggravation bit freezing hair It is raw.
When bit freezing occurs in boring procedure on sleeve pipe for drill bushing piping tool 13, following several negative consequences can be caused:When Screw motor 14 produces steep torque, and drill bushing piping tool 13 is twisted off, and causes fish, need to carry out fish salvaging, influence operation and enter Degree, increase workload and job costs;Second, casing sidetracking is unsuccessful, follow-up jet drilling formation tool operation is caused to fail, Need to repeatedly rise out with tripping in drill bushing piping tool 13 and other instruments, cause duty cycle and cost increase.
In view of the above-mentioned problems of the prior art, the present inventor combines the design and use of related manufacturing field for many years Experience, it is aided with too strong professional knowledge, there is provided a kind of rotation outlet device for boring radial water flat hole guider, it is above-mentioned to overcome Defect.
