Abstract

The invention discloses a carbonatite fracture-cavity unit body injection-production simulation experiment evaluation device.The device comprises a gas-liquid injection system, a bottom water simulation system, a fracture-cavity unit simulation system, an oil-gas-water separating and metering system and a data collection control and processing system; the gas-liquid injection system comprises a fluid storage mechanism and a fluid displacement control mechanism used for simulating displacement experiments and injecting a fluid into the fracture-cavity unit simulation system; the bottom water simulation system is used for simulating influences of bottom water with different strengths on injection and production of a fracture-cavity unit; the fracture-cavity unit simulation system comprises a fracture-cavity unit body model body and preset simulation pressure measuring points; the oil-gas-water separating and metering system comprises a gas-liquid separator, an oil-water separator and an oil-gas-water measuring meter; the data collection control and processing system comprises sensors, a simulation light source and an industrial personal computer.The carbonatite fracture-cavity unit body injection-production simulation experiment evaluation device can simulate oil well production situations of different fracture-cavity storage and collection unit spaces and simulate the influences of different bottom water on oil well production.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to an injection-production simulation experiment evaluation device for a carbonate fracture-cavity unit. Background technique [0002] Carbonate reservoirs in the Tarim Basin are the main crude oil production sites in the Tarim Basin and one of the main positions for increasing oil and gas production in China. The injection-production development of carbonate rock fracture-cavity units is a hot research direction for the development of carbonate reservoirs . In recent years, with the development of fractured-cavity reservoirs in carbonate rocks, how to simulate the injection-production simulation experiment evaluation of fracture-cavity units, how to simulate the distribution of remaining oil, and how to select the optimal injection-production method through experimental simulation have always been carbon Difficulties faced in the experimental evaluation of salt rock...
