Description
technical field [0001] The invention relates to a simulation experiment device and method, in particular to a shale reservoir diagenesis fracture simulation experiment device and method, belonging to the technical field of petroleum exploitation. Background technique [0002] In the 21st century, the demand for energy in production and life under the guidance of modern technology has grown rapidly. At this stage, fossil fuels are still in an irreplaceable position. With the rapid development of oil, the reserves of conventional oil and gas resources in the world are rapidly decreasing. Shale gas More and more attention has been paid to the development of tight oil and tight gas. However, the development of shale gas, tight oil, and tight gas is still in the basic stage, and there are still many blind spots in the understanding of tight shale reservoirs. [0003] Among them, shale oil and gas has become an important engine for the development of the petroleum industry, and t...
