High-temperature high-pressure large-scale oil-water displacement dynamic X-ray scanning experimental device

Abstract

The invention provides a high-temperature high-pressure large-scale oil-water displacement dynamic X-ray scanning experiment device, and relates to the technical field of oil-gas field exploitation experiments. The device comprises a flat rock core wrapped with a heating sleeve, the flat rock core is arranged in a thin-wall confining pressure kettle body, and a confining pressure cavity wrapping the flat rock core is arranged in the confining pressure kettle body in a sealing manner; and the confining pressure cavity is respectively communicated with a helium supply system, a water supply system and an oil supply system. A supporting kettle body supports along the edge of the confining pressure kettle body, the middle part of the confining pressure kettle body is connected with the supporting kettle body through a plurality of rib plates, a scanning channel penetrating through the flat rock core is formed between the adjacent rib plates, an X-ray scanning mechanism is arranged at the end part of the scanning channel, and the X-ray scanning mechanism is driven by a movement driving device to move along the length direction of the flat rock core; and a front-back turnover mechanism and a left-right turnover mechanism are arranged on the supporting kettle body. The problem that in the prior art, the reliability of obtained experimental data is poor due to displacement experiment simulation condition limitation is solved.

Description

technical field [0001] The invention relates to the technical field of oil and gas field exploitation experiments, in particular to a high-temperature and high-pressure large-scale oil-water displacement dynamic X-ray scanning experimental device. Background technique [0002] The development strategies and technological measures adopted by people for oil and gas reservoirs have a great influence on the final recoverable reserves of oil and gas fields. The ratio of recoverable reserves to original geological reserves is called recovery. Experiments and research on the mechanism of oil displacement play an important role in improving the recovery of oil and gas fields. In the existing flooding experiments, one is indirectly studied through factors such as inlet and outlet pressures, and the other is the low-pressure normal-temperature flat plate model flooding body, which has the disadvantage that it cannot objectively simulate the high-pressure and high-temperature environme...
