Description
One, technical field:
The utility model relates to a kind of apparatus for work of petroleum industry, and particularly a kind of cover of the various wells in the oil well operation process that is applicable to mills the integrated instrument of salvaging.
Two, background technology:
At present, it is a kind of flow chart very general in the oil field operation process that cover mills salvaging, usually the mode that adopts when carrying out this class operation is, earlier fish in the well being overlapped and milled (or repairing junk on top of fish or the cover mill off top of fish or sand etc.) cover after milling and finishing trips out the milling pipe post, changes fishing string and carry out fishing.The problem of its existence is: trouble is installed, in the process of lower tubular column, has not only increased the activity duration, also increased operating cost.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provides a kind of cover to mill and salvages integrated instrument, has saved the trouble of lower tubular column, can mill at cover and directly salvage after finishing, and makes to overlap to mill the fishing one-trip string and finish.
The technical solution of the utility model realizes in the following manner:
The utility model by mainly by bearing torque fluid cylinder, steel ball, cut off pin, packed-piston, lock dog, milling pipe joint and following circulating connection and form, described bearing torque fluid cylinder is movably connected with following circulating connection, have on the following circulating connection in order to carry out the hole of liquid circulation, bottom at the bearing torque fluid cylinder is provided with boss, and packed-piston is equipped with in the inside of bearing torque fluid cylinder, and packed-piston and the utilization of bearing torque fluid cylinder are cut off pin and be fixed together; The outer cover of described bearing torque fluid cylinder is equipped with the milling pipe joint, and the bottom of milling pipe joint has the groove that can match with the boss of bearing torque joint, and the centre of milling pipe joint is provided with a hole enlargement, by lock dog itself and bearing torque fluid cylinder is fixed together.
The bottom of above-mentioned packed-piston is provided with undergauge, and undergauge links to each other with the internal diameter of following circulating connection.
The centre of above-mentioned packed-piston is provided with a plurality of side openings.
Be provided with steel ball in the above-mentioned bearing torque fluid cylinder, cover mills the top of back steel ball seat at packed-piston.
The utility model compared with prior art has following significant effect: it is simple in structure, low cost of manufacture and safe and reliable; In addition, easy to install, can mill when salvaging at cover and descend one-trip string less, thereby save activity duration and operating cost greatly.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is A-A structure charts of the present utility model;
Accompanying drawing 3 is B-B structure charts of the present utility model;
Among the last figure: bearing torque fluid cylinder 1, steel ball 2, sealing ring 3 and 6, cut off pin 4, packed-piston 5, lock dog 7, milling pipe joint 8, circulating connection 9, boss 10, undergauge 11, side opening 12 down.
Five, the specific embodiment:
For further disclosing the technical solution of the utility model, the utility model will be further described below in conjunction with accompanying drawing 1-3:
The utility model by mainly by bearing torque fluid cylinder 1, steel ball 2, cut off pin 4, packed-piston 5, lock dog 7, milling pipe joint 8 and following circulating connection 9 and form, described bearing torque fluid cylinder 1 is movably connected with following circulating connection 9, have on the following circulating connection 9 in order to carry out the hole of liquid circulation, be provided with boss 10 in the bottom of bearing torque fluid cylinder 1, and packed-piston 5 is equipped with in the inside of bearing torque fluid cylinder, and packed- piston 5 and 1 utilization of bearing torque fluid cylinder are cut off pin 4 and be fixed together; The outer cover of described bearing torque fluid cylinder is equipped with milling pipe joint 8, and the bottom of milling pipe joint 8 has the groove that can match with the boss of bearing torque joint, and the centre of milling pipe joint 8 is provided with a hole enlargement, by lock dog 7 itself and bearing torque fluid cylinder 1 is fixed together.The bottom of packed-piston 5 is provided with undergauge 11, and undergauge 11 links to each other with the internal diameter of following circulating connection 9, and the centre of packed-piston 5 is provided with a plurality of side openings 12.
To descend circulating connection 9 to join during use with the fishing tool of using mutually, milling pipe joint 8 is continuous with corresponding milling pipe, mill or repair top of fish with overlapping earlier in the tubing string lower going-into-well, the cover that can instead circulate this moment mills salvaging, circulation fluid will be entered in the well by the tubing string outside and be entered in the pipe by the milling pipe bottom, enter into the milling pipe post by the following tapping of circulating connection 9, with circulation fluid and dirt by being circulated to ground in the pipe.
After cover mills and finishes, drop into steel ball 2 on ground, and suppress with cementing truck, steel ball 2 under the effect of hydraulic coupling and packed-piston 5 will move downward together continue to move downward the limited step of circulating connection 9 under arriving after cutting off pin 4 till.This moment, the groove of packed-piston 5 just in time faced toward lock dog 7, make lock dog 7 lose support, can freely move up and down thereby make milling pipe joint 8 lose position-limiting action, and sealing ring 6 up/down steps of packed-piston 5 just in time of this moment can not flow out flushing liquor from the hole of lock dog 7 correspondences.The undergauge place, bottom of packed-piston 5 just in time seals the circulation port of circulating connection 9 down again simultaneously, thus the square impact top of fish operation before realizing salvaging.When liquid comes downwards to the steel ball at packed-piston top during the square impact top of fish in tubing string, reenter the tubing string endoporus can wash top of fish from the side opening of packed-piston thereby walk around steel ball, flushing liquor will return to ground from the tubing string outside together with dirt in the well.After finishing, flushing transfers tubing string, this moment is because the milling pipe joint has lost restriction, so it will be up along with transferring of tubing string, thereby can make the fishing tool of milling pipe inside successfully carry out fishing, drag for and salvage the unfreezing operation after obtaining fish, after the fish unfreezing, the upper lifting pipe column jecket mills pipe again can be descending, trip out with one of tubing string limited when waiting to go downwards to the boss of bearing torque fluid cylinder 1, finish cover and mill fishing.
