Abstract

The invention discloses two parts namely a hydraulic fracturing simulation experiment device for oil shale and a manufacturing method of an experiment sample. The hydraulic fracturing simulation experiment device for the oil shale is composed of a hydraulic fracturing pressurization and data acquisition part and an experiment sample triaxial pressurization part. The crack initiation pressure and the crack propagation situation of the oil shale under different stress situations and different perforation conditions can be tested by utilizing a true oil shale test block. By virtue of the manufacturing method of an oil shale sample, an experiment can be performed by utilizing the true oil shale test block, stresses in three directions can be fully transferred to the oil shale test block, and the oil shale test block can be truly stressed.

Description

technical field [0001] The invention relates to the research field of oil shale hydraulic fracturing, in particular to an oil shale hydraulic fracturing simulation experiment system and a method for making experimental samples. Background technique [0002] With the rapid development of society and economy, human demand for fossil fuels is also increasing year by year, the output of some old oil fields is decreasing year by year, and the prices of oil and gas resources such as oil and natural gas are constantly increasing, which prompts countries all over the world to constantly look for alternative energy sources. [0003] As an unconventional energy source, oil shale has the characteristics of large reserves and high utilization value. Converting oil shale into shale oil can reach more than 400 billion tons, which is 5.4 times the original proven recoverable natural reserves in the world today. Therefore, countries all over the world are actively studying the exploitation ...
