Abstract
A pressure test equipment of well head tubing comprises a valve, an one-way valve, a pressure gauge, an adapting tube and a switch of the pressure gauge, a casing, a filter, a liquid joint, a riser, a liquid tube, a release valve, a high pressure hose, a quick joint and a well head joint. The valve is respectively linked with the casing and the riser, in which the inside is provided with the one-way valve. The one-way valve is respectively provided and connected with the filter, the liquid tube, the pressure gauge, the adapting tube and the switch of the pressure gauge. The casing is linked with the liquid joint. The riser is in sequent connection with the release valve, the high pressure hose, the fast joint and the well head joint. The utility model is provided with the one-way valve, the filter and the release valve, which has the functions of easy pressure testing with the liquid which does not return, the prevention for the falling of waste in wells and the environment protection. Therefore, the utility model can be widely applied in the tubing pressure testing process of oil well head.
Description
One, technical field
The utility model relates to oil exploitation well head pressure testing equipment, particularly a kind of well head oil pipe pressure testing device.
Two, background technology
At present, oil pipe pressure testing of oil exploitation well and the main method of observation pressure are to load onto threeway at well head oil pipe or sleeve pipe, and after the pipeline that is connected with cementing truck, valve and pressure meter reached certain pressure, valve-off was observed the pressure lifting situation of change; Or well head do not adorn threeway, directly connects the cementing truck pipeline, reach predetermined pressure after, cementing truck upward pressure table lifting situation is observed in termination of pumping.This mode exists following shortcoming or deficiency: 1. observe the pressure inconvenience, band presses valve-off dangerous, and pressure transient; 2. can not solve the problem that effluxes of oil jacket inner air tube, thereby influence the accuracy of pressure; 3. no liquid filtration facility, the solid content in the working fluid easily enters in the well, causes the inspection pump of doing over again; 4. connecting pipe such as well head cementing truck has position leakage phenomena such as joint, easily causes pressure instability.
Three, summary of the invention
The purpose of this utility model provides a kind of improved well head oil pipe pressure testing device, and shortcoming or deficiency that it can overcome effectively or avoid existing in the above-mentioned prior art can accurately be observed pressure changing again effectively, also can protect oil well to preserve from.
Well head oil pipe pressure testing device described in the utility model, comprise valve body, one way valve, pressure meter and adapter thereof and switch, sleeve pipe, strainer, liquid inlet joint, standpipe, feed tube, vent valve, high-pressure hose, snap joint, well head joint, be connected with sleeve pipe and standpipe on the described valve body respectively, one way valve is installed in the valve body, install and be connected with strainer, feed tube and pressure meter and adapter and switch on this one way valve respectively, be connected with liquid inlet joint on the described sleeve pipe, be connected with vent valve, high-pressure hose, snap joint and well head joint on the standpipe in turn.
Wherein, described filter bits is in sleeve pipe.Described feed tube is arranged in standpipe.Described valve body is provided with the hole that setting pressure table and joint, one way valve are communicated with strainer and standpipe.
The utility model has following advantage compared with prior art:
1, design has strainer, has guaranteed cleaning liquid, avoids foreign matter and the solid content well that falls, and the protection oil well is avoided doing over again.Strainer is a stainless steel cloth, does not in use corrode, and is easy to maintenance.
2, design has one way valve to guarantee that test(ing) liquid enters in the pit shaft from hydraulic test pump, and the pressure in the pit shaft can not react on hydraulic test pump.
3, the one way valve material adopts stainless steel, does not corrode in the use; The cone hard surfacing is handled, and guarantees the application life of valve body.
4, design has the annular space outlet valve, has guaranteed that the gas between the pressure testing valve collar sky is discharged, and makes test accurately.
5, pressure meter is housed above the exerciser, conveniently reads the pressure in the pit shaft, when pressure reaches regulation numerical value, close cementing truck, stagnate feed flow.Simultaneously, observe manometric reading, judge whether pit shaft inner oil tube, joint or Wel packing etc. have leakage.
6, designed high-pressure hose and directly directly be connected, prevented that well liquid lands, satisfied environmental protection requirement with well head.
7, designed water flooding vehicle joint and well head joint, realized connecting fast.
Four, description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
Five, the specific embodiment
Consult accompanying drawing, a kind of well head oil pipe pressure testing device, comprise valve body, one way valve, pressure meter and adapter thereof and switch, sleeve pipe, strainer, liquid inlet joint, standpipe, feed tube, vent valve, high-pressure hose, snap joint, the well head joint, be connected with sleeve pipe 6 and standpipe 9 on the valve body 1 respectively, one way valve 2 is installed in the valve body, install and be connected with strainer 7 on this one way valve respectively, feed tube 10 and pressure meter 5 and take over 3 and switch 4, be connected with liquid inlet joint 8 on the sleeve pipe 6, be connected with vent valve 11 on the standpipe 9 in turn, high-pressure hose 12, snap joint 13 and well head joint 14.
Strainer 7 is positioned at sleeve pipe 6.Feed tube 10 is arranged in standpipe 9.Valve body 1 is provided with the hole that setting pressure table 5 and joint 3, one way valve 2 are communicated with strainer 7 and standpipe 9.
Claims (4)
1. well head oil pipe pressure testing device, comprise valve body, one way valve, pressure meter and adapter thereof and switch, sleeve pipe, strainer, liquid inlet joint, standpipe, feed tube, vent valve, high-pressure hose, snap joint, well head joint, it is characterized in that being connected with respectively on the described valve body sleeve pipe and standpipe, one way valve is installed in the valve body, install and be connected with strainer, feed tube and pressure meter and adapter and switch on this one way valve respectively, be connected with liquid inlet joint on the described sleeve pipe, be connected with vent valve, high-pressure hose, snap joint and well head joint on the standpipe in turn.
