Problems solved by technology

Due to many years of oil exploitation in our country, high water content oil wells have appeared in single wells in many oil fields, and the oil recovery efficiency is very low, so it is necessary to manually monitor the water content of single well crude oil
However, traditional wellhead manual sampling for water cut measurement has problems such as high labor intensity, low work efficiency, inconvenient operation, slow sampling speed, unrepresentative sampling, and failure to realize information modernization.

Abstract

The invention discloses a maintenance-free single-well water content monitoring device. The maintenance-free single-well water content monitoring device comprises an oil gas separator and a pressure-regulating valve mechanism; the oil gas separator comprises a shell and a rotary blade arranged in the shell; the shell comprises an inlet and an outlet which are formed in the upper part of the shell, and an oil water outlet formed in the bottom of the shell; the position of the outlet is higher than that of the inlet; the inlet aligns with the rotary blade; the outlet position of the oil gas separator is connected with a conveying pipeline; a third pressure-regulating valve is arranged on the conveying pipeline; the pressure-regulating valve mechanism comprises a monitoring pipeline communicated with the oil water outlet, and a first pressure-regulating valve, a sensor and a second pressure-regulating valve which are arranged on the monitoring pipeline sequentially; the pressure of the first pressure-regulating valve is higher than that of the second pressure-regulating valve. The maintenance-free single-well water content monitoring device separates gas and an oil water mixed medium that are contained in crude oil, automatically monitors the water content of the crude oil, and has the advantages of simple structure, low manufacturing cost and the like.

Description

technical field [0001] The invention belongs to the technical field of oilfield instrumentation equipment, in particular to a maintenance-free single well water content monitoring device. Background technique [0002] Water cut is one of the most basic and important control parameters in the production process of major oil fields, which is related to the output, quality, efficiency of products, life and safety of production equipment and other aspects. The single well water cut monitoring device is a precision instrument for measuring the water cut of crude oil in a single well, and is mainly used for measuring the water cut of crude oil on a single wellhead in the oil production area of ​​each major oil production plant. Due to years of oil exploitation in our country, high water-cut oil wells have appeared in single wells in many oil fields, and the oil recovery efficiency is very low, so it is necessary to manually monitor the water content of single well crude oil. ...
