Description
Technical Field
The utility model relates to an oil theftproof protection technical field, in particular to oil recovery well sample theftproof protection device.
Background
The production wells of general oil fields are distributed in the field, the distance between well sites of the oil fields is large, the anti-theft protection link of the oil fields is weak, in recent years, the phenomenon that molecules are stolen on sampling ports of oil areas to steal crude oil by bags often occurs, great loss is caused to development management and economic benefit of the oil fields, the problem of local serious environmental pollution is caused, and great production and environmental protection influence is caused to crude oil production of the oil areas.
Disclosure of Invention
In order to solve the technical problem, the utility model aims to provide a producing well sample theftproof protection device has solved the problem that oil well sample connection stolen oil case frequently, runs off to reducing crude oil, has played positive effect in the aspect of reducing environmental pollution etc..
In order to realize the purpose, the utility model discloses a technical scheme is:
oil recovery well sample theftproof protection device, including main sleeve 2, main sleeve 2 divide into the triplex, be the annular structure of upper portion, the conical structure at middle part and the annular structure of lower part down respectively, the annular structure bottom of lower part is provided with entrance point joint 7, the annular structure top of upper portion install end cover 1, the annular structure inside of upper portion is provided with guide post 3, the conical structure department at middle part is provided with exit end endotheca 5, exit end endotheca 5 links to each other with the inside piston 4 that has third sealed fluororubber circle 10, the annular structure inside of lower part be hollow cavity, the cavity is inside to be equipped with main spring 6, main spring 6 upper end and exit end endotheca 5 contact, the lower extreme is fixed with the interior spring coupling on the entrance point joint 7.
The guide post 3 and the main sleeve 2 are welded.
The main sleeve 2, the end cover 1 and the inlet end joint 7 are connected by detachable threads.
And a second sealing fluororubber ring 9 is arranged between the main spring 6 and the outlet end inner sleeve 5.
The top of the main spring 6 is provided with a first sealing fluororubber ring 8.
And a fourth sealing fluororubber ring 11 is arranged on the inner side of the annular structure of the upper part and above the guide post 3.
The beneficial effects of the utility model reside in that:
the anti-theft protection sampling device is simple in structural design, has good anti-theft capacity, solves the problem that oil-stealing cases frequently happen at an oil well sampling port, and plays a positive role in reducing crude oil loss, reducing environmental pollution and the like.
Drawings
Fig. 1 is a structural diagram of a wellhead anti-theft protection device.
Fig. 2 is a sectional view a-a of fig. 1.
Detailed Description
The following detailed description is made with reference to the accompanying drawings.
As shown in fig. 1 and fig. 2, the end cover 11, the main sleeve 2 and the inlet end connector 7 are detachably connected through threads, the main sleeve 2 and the guide column 3 are connected in a welding mode, and other internal components are connected in a mechanical fit mode and are fastened internally through a clamp spring.
The device is composed of an internal cavity component and an external structure component, a third sealing fluororubber ring 10 of an internal piston 4 is arranged on an outlet end inner sleeve 5, a main spring 6 is arranged in the cavity, and a threaded connection inlet end joint 7 is clamped at the bottom of the internal spring and then screwed to the bottom of threads. So that the inner cavity thereof is fixed inside the device. When the sampling device is not used, the end cover 1 is arranged on the device equipment, the end cover 1 is removed when the sampling device is used, the sampling wrench is arranged in the device along the guide groove, the piston channel is opened by extruding the spring, the sampling target is realized, the wrench is rotated in the opposite direction after sampling is finished, the channel is closed, the sampling wrench is taken out, and the end cover 1 is screwed down.
The utility model discloses the theory of operation:
when the device is not used for sampling, the end cover 1 is covered on the connecting seat component and then the component is locked.
When the device is used for sampling, the end cover 1 component is unscrewed, then the sampling wrench component is installed in the device along the guide column 3, the wrench is rotated, the main extrusion spring 5 opens the inner piston 4 to enable liquid to enter a channel, and sample liquid enters the sampling wrench cavity. When the sample liquid is sufficiently sampled, the wrench is rotated in the opposite direction, the main spring 5 is restored to the original state, the internal piston 4 closes the channel and is sealed by the fluororubber, the device returns to the initial position, and the liquid channel is closed.
