Abstract

The utility model relates to an anti-pollution device for anchoring, stabilizing, contacting and liquid leakage, which particularly relates to an oil field downhole tool for anchoring, stabilizing, contacting and liquid leakage for oil well pipe columns with different diameters. The device is composed of an upper joint, a sealing ring, a slip barrel, a slide sealing sleeve, an O-shaped sealing ring, a connecting pipe, a slip, pins, a spring, a stabilizing block, screws, a slip retainer ring, a stabilizing body, a pressure ring, a center pipe and a lower joint. A stabilizing anchoring mechanism is composed of the slip, the pins, the spring, the stabilizing block, the screws, the slip retainer ring, the stabilizing body and the pressure ring. The utility model has the advantages that anchoring, relieving anchor, opening or closing a liquid discharging pore canal and a cycle passage are reached through the rotation of an oil pipe and a stabilizing and anchoring mechanism by lifting and lowering operation, and the oil pipe moves in a symmetric closed rail groove of a center pipe. And the utility model has the advantages of multifunction, safety, reliability, pollution prevention, etc.

Description

Grappling, set upright, contact and drainage environmental control system

Technical field

The utility model relate to the various different-diameters in a kind of oil field the oil well pipe grappling, set upright, conduct electricity contact and the downhole tool used of drainage.

Background technology

At present, the grappling of oilfield tubing string, set upright, contact conduction and drainage instrument commonly used has oil pipe anchor, tubing centrilizer, conduction contactor and bleeder, function of use is single, and instrument accumulation cost height, oil pipe anchor are that the grappling action is finished in hydraulic control, when removing grappling, because oil, casing pressure is uneven, makes the working fluid cylinder piston be subjected to certain differential pressure action all the time, anchor watt can not be regained fully, gently then cause casing damage, heavy then cause the workover accident.The bleeder body is connected on the tubing string, and gauge tap is connected on the rod string.In rod string moves back and forth because hole deviation, variation of temperature, fluctuating load and artificial operation, bleeder open by mistake and phenomenon that piston can not enter pump barrel often has generation.In the well workover process, liquid flows on the ground during lift pipe string especially, and it is harmful again to cause ground environment to pollute.

Summary of the invention

In order to overcome existing oil well pipe grappling, set upright, the problem that contact and drainage downhole tool exist, the utility model provides a kind of grappling, set upright, contact and drainage environmental control system, this device is mainly with grappling, set upright, contact and drainage are combined into one, there are two leakage openings of symmetry the central tube upper end, in the well workover process, during lift pipe string, leakage opening on the central tube is opened, the interior liquid of tubing string is flowed in the well, prevent ground pollution, there is symmetrical closed type rail groove the outer wall both sides of central tube, set upright anchor mechanism and move in rail groove, have guaranteed the tubing string grappling, set upright, the function of contact and drainage realizes.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of grappling, set upright, contact and drainage environmental control system, mainly by top connection, joint ring, the slips tube, the slipper seal cover, " O " RunddichtringO, tube connector, slips, pin, spring, wiper block, centralizer body, the slip ring pin, slip ring, pressure ring, central tube and lower contact are formed, its special character is the rail groove that there is symmetrical closed type the central tube outer wall both sides between pressure ring and the lower contact, there are two leakage openings of symmetry the upper end of central tube, between the outside, central tube upper end and the slips tube joint ring is arranged, slipper seal is enclosed within the lower end of joint ring, sets upright anchor mechanism by slips, pin, spring, wiper block, screw, the slips back-up ring, centralizer body and pressure ring constitute.

The beneficial effects of the utility model are: by the rotation of oil pipe, on put and put operation and make and set upright anchor mechanism, in central tube symmetry closed type rail groove, move, reach grappling, remove grappling, open or close drainage duct and circulation canal, have multi-functional, safe and reliable, advantage such as anti-pollution.
