Abstract
The utility model relates to a pressure testing, sampling and theft protection device of oil well production tree, comprising an outer working barrel, a base, a spring, a steel ball, a ball seat, an anti-theft lock, a plug and a pressure testing sampling pipe. The left end of the outer working barrel is provided with external thread and connected with the nozzle tip sleeve and welded tightly, the inner circle is provided with a boss, and the inner side of the bore of the boss is provided with internal thread. The circular bore of the right end of the outer working barrel is provided with internal thread and a lock groove. The base is tubular, the left end is provided with external thread and connected with the outer working barrel, and the right end is provided with internal thread and connected with the ball seat. The inner side of the base is provided with the spring and the steel ball, and the pressure testing sampling pipe is connected with the ball seat. When the pressure is measured, the valve of the pressure gauge is opened; when the sample is sampled, the sampling valve is opened. Therefore, the data of the oil well can be recorded. When the data is recorded, the pressure testing sampling pipe is detached, and after the anti-theft lock is locked and the plug is installed, the anti-theft purpose is realized. Then the oil well is in the regular production state.
Description
Technical field:
The utility model belongs to the improvement of the pressure measurement of a kind of well recovery tree, sampling, anti-theft device.
Technical background:
At present; during each oilfield production tree ordinary production; outermost end at the oil nozzle cover is equipped with plug; and for detector tube linear pressure and drawing oil sample; on upright conduit, pressure meter valve and sample cock are installed; but because the oil well major part all is in the field, wilderness; lawless person regular meeting is at plug; pressure meter valve place; oil is stolen at the sample cock place; so; each oil field is for antitheft; can only be with plug; the pressure meter valve; sample cock is all shut; this brings very burden for the daily management and the admission data of oil well, can't obtain well head data accurately, and just being difficult to has appropriate analysis to the oil well hole condition; can't take rational control measures to oil well, in order to overcome the above problems.The utility model provides the pressure measurement of a kind of well recovery tree, sampling, anti-theft device, it is compared with conventional device, can once finish pressure measurement, sampling, antitheft work at oil nozzle cover place, and when processing pipeline, need not put to press and unload plug, reduce crude oil loss and environment pollution.
Summary of the invention:
The utility model is in order to solve existing oilfield production tree pressure measurement, sampling, problem such as antitheft.It is that an outer working tube is installed at oil nozzle cover place, does not have theftproof lock in the tube, can play antitheft effect, during sampling, opens lock, and the pressure measurement probe tube of screwing on can carry out the admission of pressure and the sampling work of oil well.Unload the pressure measurement probe tube after having enrolled data, install theftproof lock and plug, can play antitheft effect, the purpose of this utility model provides the pressure measurement of a kind of well recovery tree, sampling, anti-theft device for oilfield exactly.
The utility model is achieved in that outer working tube (1) left end cylindrical is processed with screw thread, and interior circle is processed with a boss, is processed with screw thread in the boss hole.Be processed with screw thread and locked groove in the right-hand member cylindrical endoporus, base (2) is a tubular, and left end is processed with external screw thread and is connected with urceolus (1), right-hand member is processed with internal thread and is connected with ball seat (5), spring (3) and steel ball (4) are arranged in the base, and steel ball (4) contacts with ball seat (5), and sealing is not leaked.Pressure measurement probe tube (9) is connected with ball seat (5).Lock (6) is provided with lock core for cylindrical centre, and the horizontal place of cylinder-type lock is processed with through hole, and the cylinder tooth of unblanking is installed in the through hole, and can be installed in the interior locked groove place of outer working tube (1).Pressure measurement probe tube (9) is a pipe, and an end is processed with O-ring seal (8), screw thread is arranged behind the sealing ring (8) and is connected with ball seat (5).The pressure measurement probe tube also is equipped with pressure meter valve and sample cock on (9).Ball seat (5) is processed with internal and external screw thread respectively for two ends, and the center is the cylinder of through hole, and external screw thread is connected with base (2), and internal thread is connected with pressure measurement probe tube (8).

The specific embodiment:
Now the utility model is described further in conjunction with the pressure measurement of well recovery tree, sampling, anti-theft device schematic diagram.The outer working tube and the oil nozzle cover of the well recovery tree pressure measurement that processes, sampling, anti-theft device are connected, when oil well needs the pressure measurement sampling, plug is unloaded, open and take off theftproof lock again with key, the pressure measurement probe tube of screwing on then makes it to back down steel ball, opens the pressure meter valve during measuring pressure, open sample cock during sampling, so just can enroll pressure and sampling work.
After the data of having enrolled, unload the pressure measurement probe tube, lock theftproof lock, first-class plug, the production of just can normally recovering the oil is because the effect of theftproof lock and plug, make the lawless person can't steal crude oil, play antitheft purpose, and when stylet, only need unload plug, open theftproof lock, the car that connects processing pipeline gets final product processing pipeline, does not need to put to press to unload plug, has reduced crude oil loss and environment pollution.
