Intelligent anti-theft recording and sampling device

Abstract

The invention discloses an intelligent anti-theft pressure recording and sampling device which comprises a rotational flow mixer, an intelligent remote control valve, a remote control, a tee joint, ametering cavity, a pressure gauge, hand control valves and clamps. The first clamp is connected with the input end of the rotational flow mixer, and the output end of the rotational flow mixer is in pipeline connection with the first end of the tee joint. The second end of the tee joint is in pipeline connection with the second clamp through the first hand control valve, and the third end of the tee joint is in pipeline connection with the input end of the intelligent remote control valve. The output end of the intelligent remote control valve is connected with one end of the metering cavity,and the other end of the metering cavity is provided with the pressure gauge. A sampling oil pipe is arranged in the middle of the metering cavity, and the second hand control valve is arranged on thesampling pipe. The original flow is reserved to be unchanged, the matched special remote control is used to control opening and closing of the intelligent remote control valve to sample and record the pressure, and crude oil leaking-out is avoided after sampling and pressure recording are completed, so that the effects of sampling, pressure recording and theft prevention are achieved; and meanwhile, the sampling and pressure recording time is set every day, repeated labor is avoided, the labor intensity of workers is relieved, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a wellhead fitting device for a wellhead Christmas tree, in particular to an anti-theft pressure recording and sampling device. Background technique [0002] Oil wellhead sampling valve is an important device in oil and gas production. In the past, criminals used this valve to carry out illegal and criminal activities of stealing oil and gas, causing great losses to oil fields. In order to reduce the loss of oil and gas, the sampling and pressure recording valves on the wellhead were welded and refitted on the single-well pipeline in the oil field for a considerable period of time. There is a big error between the sampling pressure and the actual situation of the wellhead caused by the unit, and it is easy to mislead the geological technology department and the decision-making layer to analyze and judge the production status of the oil well. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide...

[0002] Oil well wellhead sampling valve is an important device in oil and gas production. In the past, criminals used this valve to carry out illegal and criminal activities of stealing oil and gas, which caused great losses to the oil field.

In order to reduce the loss of oil and gas, the sampling and pressure recording valves on the wellhead were welded dead in the oil area for a considerable period of time, and they were refitted on the single well pipeline. There is a large error between the sampling pressure recording and the actual situation of the wellhead caused by the unit, which is very easy to mislead the geological technology department and decision-making level to analyze and judge the production status of the oil well
