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. The pipe pressure elimination sampling valve comprises a flow adjusting valve body, a sampling valve body and an oil discharging valve body. A flow adjusting valve seat is arranged inside the flow adjusting valve body; an oil inlet channel is formed in the position, at one end of the flow adjusting valve seat, of the flow adjusting valve body, and an oil outlet channel is formed in the position, at the other end of the flow adjusting valve seat, of the flow adjusting valve body; a flow equalizing hood is mounted in the position, at the upper end of the flow adjusting valve seat, of the flow adjusting valve body; a flow adjusting valve element is arranged inside the flow equalizing hood; the topend of the flow adjusting valve element is connected with a flow adjusting valve rod; and the flow adjusting valve rod penetrates through a flow adjusting valve cover to be connected with a flow adjusting hand wheel. Stopping of oil conveying is achieved; adjustment of flow conveying is convenient; continued conveying of oil is achieved; oil sampling accuracy is improved; and the difficult sampling problem caused by the pressure in an oil supply pipeline is avoided.

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...
