Description
Technical field
The utility model relates to a kind of water injection well in oil fields wellhead assembly, particularly a kind of wellhead of water injection well water intaking movable fixture.
Background technology
In field produces, wellhead of water injection well pressure is high, and danger coefficient is high.Wellhead of water injection well was equipped with water intaking valve in the past, and because safety factor is low, the reusable number of times of intake switch is low, and oil field Uniform provisions does not allow welded and installed again; Or unload oil pressure gauge from the water intaking of installation water meter pipe nipple, or because water injection well pressure is high, switch handwheel often becomes expendable consumed product, and this does not all meet safety and health low production cost, energy-saving and cost-reducing production requirement.This proposes new requirement to the water intaking work doing wellhead of water injection well water quality test.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of wellhead of water injection well to fetch water movable fixture, easy to operate, to save manpower, cost low, safe and reliable.Applied widely, be applicable to the water intaking work of wellhead of water injection well water quality test.
Its technical scheme is: comprise valve body, high pressure elbow and connecting rod, the outer wall of described valve body is provided with flange external screw thread, one end of valve body is provided with pipe wrench fixture block, high-voltage tube is provided with in the outside of pipe wrench fixture block, the outer end of described high-voltage tube is provided with external screw thread, be connected to high pressure elbow by external screw thread, the two ends of described high pressure elbow are respectively equipped with high pressure elbow internal thread, and connecting rod is connected with high pressure elbow by connecting rod external screw thread.
The inner chamber of above-mentioned valve body is horn mouth shape, and slot is identical with the internal diameter of high-voltage tube.
Above-mentioned pipe wrench fixture block is provided with multiple rib.
The beneficial effects of the utility model are: a people just can operate, and can be communicated with flange interface and be fixed on injection well tubing flange, and open oil pipe and go out port strobe, carry out water intaking chemical examination work.After collecting sample, close oil pipe and go out port strobe, unload the removable water fetching device of wellhead of water injection well, reclaim after wiped clean and treat that next time uses.This device is capable of circulation repeatedly to be used, and meets current safety environmental protection, energy-saving and cost-reducing production requirement.
Accompanying drawing explanation
Accompanying drawing 1 is that structure of the present utility model is scattered figure;
Accompanying drawing 2 is lateral views of valve body part of the present utility model;
In upper figure: flange external screw thread 1, pipe wrench fixture block 2, high-voltage tube 3, high pressure elbow internal thread 4, high pressure elbow 5, connecting rod external screw thread 6, connecting rod 7, valve body 8.
Detailed description of the invention
By reference to the accompanying drawings 1 and 2, the utility model will be further described:
The utility model comprises valve body 8, high pressure elbow 5 and connecting rod 7, the outer wall of described valve body 8 is provided with flange external screw thread 1, one end of valve body 8 is provided with pipe wrench fixture block 2, high-voltage tube 3 is provided with in the outside of pipe wrench fixture block 2, the outer end of described high-voltage tube 3 is provided with external screw thread, be connected to copper high pressure elbow 5 by external screw thread, the two ends of described high pressure elbow 5 are respectively equipped with high pressure elbow internal thread 4, and the connecting rod 7 of steel is connected with high pressure elbow 5 by connecting rod external screw thread 6.
Wherein, the inner chamber of valve body is horn mouth shape, and slot is identical with the internal diameter of high-voltage tube 3, and from large to small, it is slow for falling anxious to water stream channel, controls current open flow scope, is convenient to the water intaking work at well head.Valve body disposal molding, safety factor is high, and high pressure resistant, hole is impacted; The copper high pressure elbow of choice for use, the connecting thread at its two is anti-high pressure filament screw thread, connects closely, do not have overflow phenomena, ensure that safety in production in use work.
In addition, pipe wrench fixture block 2 is provided with multiple rib, is convenient to spanner and rotates, also can be set to irregularly shaped, play anti-theft function.Other supporting flexible pipes of the extensible loading of connecting rod of choice for use or steel pipe use, and extend it and use length, slow down current, can prevent the oxygen in air from too much infiltrating impact water intaking quality when fetching water; Also not by the restriction of distance, away from raised platform around a well, in safety zone work, and the environmental protection of production area can be ensure that when fetching water.
During use, first each parts are connected successively, then flange interface can be communicated be fixed on injection well tubing flange, open oil pipe and go out port strobe, carry out water intaking chemical examination work.After collecting sample, close oil pipe and go out port strobe, unload the removable water fetching device of wellhead of water injection well, reclaim after wiped clean and treat that next time uses.This device is capable of circulation repeatedly to be used, and meets current safety environmental protection, energy-saving and cost-reducing production requirement.
