Horizontal well AICD intelligent water controlling sieve tube performance testing system

Abstract

The invention discloses a horizontal well AICD intelligent water controlling sieve tube performance testing system which comprises a high pressure plunger pump, an AICD intelligent water controlling sieve tube, an emulsifying tank, a heater, a safety valve, a sampling valve, a bypass pipeline, a real-time monitoring display system, and a PLC control platform. The inlet of the AICD intelligent water controlling sieve tube is connected with the outlet of the high pressure plunger pump by a flange, the high pressure plunger pump is connected with the emulsifying tank by a flange, a high-frequencyemulsifying machine is arranged at the upper end of the emulsifying tank, the heater is arranged on the tank body, the emulsifying tank is connected with the outlet of the AICD intelligent water controlling sieve tube by a rubber tube, an oil-water mixture simulating subsurface reservoir is contained in the tank; the sampling valve, a digital pressure gauge and a flowmeter are arranged at two ends of the intelligent water controlling sieve tube; a PLC master control platform is connected with the real-time monitoring display system by a circuit, so as to monitor system operation and key testing data in real time. The testing system disclosed by the invention is simple in structure, high in strength and good in performance, and aims at simulating the subsurface production condition by ground test, so as to test the oil stabilizing and oil controlling performance parameters of the AICD intelligent water controlling device.

Description

technical field [0001] The invention relates to a horizontal well AICD intelligent water control screen pipe performance test system, which belongs to the technical field of oilfield horizontal well exploitation. Background technique [0002] At present, most domestic oil fields have entered the period of medium-high water cut, and the output of production wells drops rapidly with the increase of water cut, which greatly affects the oil recovery efficiency. Horizontal wells are widely used in oilfield production as an important means to increase single well production and change development methods. AICD intelligent water control device provides a brand-new process technology for solving the problem of high water cut in oil wells with its unique intelligent water control and oil increase characteristics. Through reasonable design, the flow resistance level of AICD increases with the increase of water cut, so as to achieve the purpose of stabilizing oil and controlling water...

AI Technical Summary

Problems solved by technology

However, at present, in the application process of domestic AICD in horizontal wells, it is often determined based on experience, and the performance parameters of AICD intelligent water control device in the horizontal section cannot be tested for oil stabilization and water control.
