Problems solved by technology

[0002] With the continuous development of the economy, the consumption of energy is also increasing. With the gradual increase of the mining time, it is necessary to sample and detect the continuously extracted oil at the initial stage and during the mining process, which is conducive to fully To understand the physical characteristics of the formation where oil exists, provide powerful data for further oil extraction, and ensure the quality of oil extraction. At present, flow control valves are installed on oil transmission pipelines, but their functions are single, and they only have the function of opening and closing. Sampling provides effective help, and the method of digging on the pipe wall is not advisable

Abstract

The invention discloses a pipe pressure elimination sampling valve device for oil exploitation, which comprises a flow regulating valve body, a sampling valve body and an oil discharge valve body. The flow regulating valve body is provided with a flow regulating valve seat inside the flow regulating valve The flow regulating valve body at one end of the seat is set as an oil inlet channel, and the flow regulating valve body at the other end of the flow regulating valve seat is set as an oil outlet channel. There is a flow regulating spool inside the flow equalizing hood, the top of the flow regulating spool is connected to the flow regulating valve stem, and the flow regulating valve stem passes through the flow regulating bonnet to connect to the flow regulating handwheel; the stop of oil delivery is realized, and the flow transportation can be adjusted conveniently, realizing oil The continuous delivery improves the accuracy of oil sampling and avoids the problem of difficult sampling caused by the pressure in the oil supply pipeline.

Description

technical field [0001] The invention relates to the technical field of oil extraction equipment, in particular to a pipe pressure elimination sampling valve device for oil extraction. Background technique [0002] With the continuous development of the economy, the consumption of energy is also increasing. With the gradual increase of the mining time, it is necessary to sample and detect the continuously extracted oil at the initial stage and during the mining process, which is conducive to fully To understand the physical characteristics of the formation where oil exists, provide powerful data for further oil extraction, and ensure the quality of oil extraction. At present, flow control valves are installed on oil transmission pipelines, but their functions are single, and they only have the function of opening and closing. Sampling provides effective help, and the method of digging on the pipe wall is not advisable. Therefore, there is a need for a pipe pressure eliminati...
