Thickened oil watering regulation-free device

Abstract

A thickened oil watering regulation-free device used in oil field comprises a shell, an inlet, a screwed plug, a sealing ring, a filter screen, a nozzle and a pressing cap, wherein the device has a T-shaped cylinder structure; the left end of the shell is provided with internal threads while the interior of the right end is provided with internal threads; the external threads on the right end of the filter screen are connected to the internal threads of the pressing cap; the filter screen and the pressing cap tightly press the nozzle; the sealing ring is arranged between the filter screen and the nozzle; the external threads on the pressing cap are connected to the internal threads inside the right end of the shell; the sealing ring is respectively arranged between the left and right ends of the filter screen and the shell; the screwed plug is connected to the internal threads of the left end of the shell; and the inlet is arranged in the middle part of the shell and is opposite to the filter screen. The device of the invention is simple in structure and convenient in assembling, can relieve the working difficulty of staff, can increase the accuracy of measuring oil well watering and efficiently avoid the inaccurate watering measurement caused by watering fluctuation, at the same time, the device can increase the crude oil measuring accuracy and is significant to completely and accurately take the primary data and draw up the extracting allocation and development program in the oil-field development process.

Description

technical field [0001] The invention relates to the technology of a water-mixing tool for heavy oil exploitation in an oil field, in particular to a control-free device for mixing heavy oil with water. Background technique [0002] Water mixing in oil wells is a method of accompanying transportation and viscosity reduction for the production of heavy oil and low-yield wells, which requires the use of gates for water volume control. Due to the problems of large measurement errors, poor stability, and inconsistent measurement systems of the water-mixing meter, the site usually stops the well regularly to calibrate the water-mixing coefficient and compares it with the metering data of the separator. Difficult, due to the influence of unstable water volume changes and measurement errors, it is impossible to accurately measure the production of oil wells, which brings great difficulties to crude oil measurement and measure formulation.
