Oil field single-well two-phase automatic metering device

Abstract

The invention discloses an oil field single-well two-phase automatic metering device, and relates to the field of oil field produced liquid metering. The oil field single-well two-phase automatic metering device is particularly suitable for the field of oil field low-yield block single-well oil production metering, and comprises a metering produced liquid inlet pipe, a metering produced liquid outlet pipe, a right piston metering cavity and a left piston metering cavity, wherein a right piston is movably connected into the right piston metering cavity in a sealed mode; the right piston metering cavity is connected with the metering produced liquid inlet pipe through a right piston inlet electric valve; the right piston metering cavity is connected with the metering produced liquid outlet pipe through a right piston outlet electric valve; and a right piston connecting rod is connected to the right piston. The oil field single-well two-phase automatic metering device is simple in structure and convenient to use, the pistons are pushed to continuously move through pressure of oil well produced liquid, valve switching and piston movement cooperation are completed through a linkage device and a valve switching contact switch, and finally single-well oil production continuous and accurate metering is achieved. The high-low-yield block oil field crude oil production management efficiency is improved.

Description

technical field [0001] The invention relates to the field of liquid production metering in oil fields, and is especially suitable for the field of single well oil production metering in low-yield blocks of oil fields, in particular to an oil field single well two-phase automatic metering device. Background technique [0002] Oilfield single well measurement is a basic work with a huge workload. The accuracy, authenticity and reliability of the measurement data directly affect the reasonable development deployment and economic benefits of the oilfield. Due to the existence of many problems such as low liquid production rate of a single well, gas content, sand production, wax formation, and intermittent liquid production in intermittent pumping, there is no single well metering technology that is widely used in oilfields at this stage, and major oilfields are still in research and exploration. stage, especially in the Yanchang Oilfield currently carrying out CO, oil flooding, ...

Problems solved by technology

Due to the existence of many problems such as low liquid production rate of a single well, gas content, sand production, wax formation, and intermittent liquid production in intermittent pumping, there is no single well metering technology that is widely used in oilfields at this stage, and major oilfields are still in research and exploration. stage, especially in the Yanchang Oilfield currently carrying out CO, oil flooding, polymer flooding, microbial flooding, water flooding and other enhanced oil recovery projects, all require a more accurate evaluation of the implementation plan, which requires a single Well metering puts forward higher requirements, so a more in-depth analysis of single well oil and gas production, more detailed research on metering technology, and the development of an oilfield single-well two-phase automatic metering device with high precision and wide application range are very necessary
