Oil well antitheft box set

Abstract

The invention relates to the technical field of burglary prevention of oil fields, and in particular, discloses an oil well antitheft box set. Antitheft boxes are mounted on an oil transmission pipe, and comprise a union antitheft box, a pressure gauge antitheft box and a sampling antitheft box; the union antitheft box and the pressure gauge antitheft box comprise upper shells and lower shells; the lower shells comprise left shells and right shells; locking structures are arranged between the left shells and the right shells; the sampling antitheft box comprises a plug shell and a sample port shell; the plug shell comprises a left shell and a right shell; a locking structure is arranged between the left shell and the right shell; and novel columnar locks are distributed between the left shells and the right shells, between the upper shells and the lower shells and between the plug shell and the sample port shell. The oil well antitheft box set has the following advantages: the antitheft boxes can effectively use the actual shape of a well mouth for protecting the well mouth under the condition of smallest volume to prevent crude oil from being stolen, and are matched with the novel columnar locks as an antitheft lock for use to prevent violent break by cutting nippers and hacksaws.

Description

technical field [0001] The invention relates to the field of oil field anti-theft technology, in particular to an oil well anti-theft box set. Background technique [0002] There are many anti-theft schemes for oil products in the oil field industry. From the perspective of wellhead anti-theft, the main oil production is physical anti-theft measures. Using box cover protection to prevent crude oil from being stolen from the wellhead, there are still many problems in the existing wellhead physical anti-theft measures, mainly in the following three ways: [0003] Anti-theft box: A large metal box is used to cover the entire wellhead. Although it can reduce the access of oil-related criminals to the wellhead, it has the characteristics of being bulky, easy to crack, and affecting the normal work of oil workers. [0004] Traditional anti-theft box: A small metal box is used to cover part of the wellhead components. Although the volume is small, most of the existing anti-theft b...

Problems solved by technology

[0005] Anti-theft sampling port: use the quick-open sampling port for sampling. In theory, there is no special sampling port to allow crude oil to flow out, but if oil-related criminals use a pipe wrench, they can forcibly twist it off

[0006] Most of the existing anti-theft facilities are connected by hinges, which are easy to be cracked by violence
