Problems solved by technology

[0002] Oil quantity Oil is an important task in oil and gas metering. However, with the continuous development of oil fields, the gas production of oil wells decreases year by year. Slow, unable to grasp the liquid production rate of a single well every day, which will affect the production measurement, and at the same time lead to the prolongation of the downtime of the combined wells, which will affect the production of the oil well and reduce the oil recovery rate

Abstract

The invention discloses a sensing control device for well logging. The sensing control device for well logging comprises a tubular sampling nozzle body, one end of the sampling nozzle body is a fluidinlet end, the other end of the sampling nozzle body is a fluid outlet end, a connector capable of being connected with an oil well wellhead casing pipe is formed at the fluid inlet end, and a sampling nipple capable of being connected with a sampling bag in a sealed mode is formed at the fluid outlet end. A spherical valve is arranged on the sampling nozzle, a layer of protection is added for collection of a gas sample, plugging is tighter, personal safety is guaranteed, and control is conducted by rotating a control handle, so that convenience is achieved. A clamping and screwing groove canbe matched with clamping teeth of a common wrench, operation is easy, and the sampling nozzle can be conveniently and firmly connected with the oil well wellhead casing pipe.

Description

technical field [0001] The invention relates to the technical field of oil drilling and production equipment, in particular to a sensor control device for well logging. Background technique [0002] Oil quantity Oil is an important task in oil and gas metering. However, with the continuous development of oil fields, the gas production of oil wells decreases year by year. Slow, it is impossible to grasp the liquid production rate of a single well every day, which will affect the production measurement. At the same time, it will prolong the shutdown time of the combined wells, affect the production of oil wells, and reduce the oil recovery rate. Contents of the invention [0003] The problem to be solved by the present invention is to provide a sensor control device for well logging, which can reduce the pressure in the pipeline or reduce the loss of crude oil, and avoid the expansion of pollution progress. Shorten the shut-down time of combined wells and increase the singl...
