Embodiment 1

[0046] This embodiment takes comparative observation test as an example to further introduce the invention.

[0047] 1) Install two tempered glass test equipment, one is a tempered glass tube installed in the automatic inflow control device, and the other is a tempered glass tube installed in a conventional nozzle. The pressure inside the cylinder is the same on both sides. The barrel diameters on both sides are exactly the same.

[0048] 2) Turn on the circulation system, so that the single-phase fluid in the water storage tank or oil storage tank enters from the liquid inlet of the tempered glass test equipment and flows out from the liquid outlet under the pump pressure.

[0049] 3) When the liquid is oil (such as viscosity 1-150Cp), after the value is stable, record the outlet flow of the two tempered glass tubes (due to the high viscosity and low flow rate of the oil, the oil flow into the automatic inflow control device is not controlled. Therefore, the two flowmeters ...

Abstract

The invention relates to an automatic inflow control device performance test system and method, characterized by comprising a circulatory system, a metering system, a data acquisition and processing system and a performance test system; the circulatory system provides a single-phase or multi-phase test fluid and also recycles the test fluid; the metering system is used for detecting temperature, pressure and flow data of the single-phase or multiphase fluid in the circulatory system and sends to the data acquisition and processing system; a to-be-tested automatic inflow control device is arranged in the performance test system, the performance test system is connected with a test fluid supply pipeline of the circulatory system and used for testing performance of the to-be-tested automaticinflow control device according to the single-phase or multiphase fluid provided by the circulatory system and sending test data to the data acquisition and processing system; and the data acquisitionand processing system is used for analyzing and processing data acquired by the metering system and the performance test system. The system provided by the invention can be widely applied to performance test of the automatic inflow control device.

Description

technical field [0001] The invention relates to the field of petroleum engineering, in particular to a performance testing system and method of an automatic inflow control device. Background technique [0002] Bottom water coning and premature water flooding of production wells are one of the most common problems in oil production. At present, conventional passive inflow control tools have a limited effect on water cone suppression, while automatic inflow control tools have a better suppression effect in theory, but have not yet been widely used. Major companies at home and abroad have developed automatic inflow control tools with intelligent selection and suppression functions for fluids. According to different principles and tool structures, they can be divided into clip type, floating disc type, flow channel control type and self-expanding type. kind. Automatic inflow control tools have broad application prospects and development space in my country's oilfields with str...
