3 results about "Shale oil" patented technology

The invention discloses an on-line monitoring device and method for in-situ mining of shale oil through combination of laser and supercritical water. The on-line monitoring device comprises a laser generating device, a gas generating device, a supercritical water generating device, a heating device, an on-line monitoring device and the like. The laser generating device generates high-energy laser beams, the gas generating device generates active gas, the oil shale layer is heated underground through the heating device, the online monitoring device monitors in-situ shale oil exploitation conditions online and observes operation site pictures in real time, and the supercritical water injection device injects generated supercritical water into the oil shale layer. And entering a pore throat. The high-energy laser beam acts on the active gas, so that the gas is activated, an explosive thermal chemical reaction occurs, the oil shale is crushed and chemically modified, and finally the shale is quickly crushed. According to the method, environmental pollution caused by shale oil in the ground refining process can be avoided, the economic benefit is high, the production cost can be effectively reduced, the working efficiency is improved, and the oil yield is greatly improved.

The invention relates to a solvent extraction method for hydrocarbon substances in a trace rock sample, and relates to the technical field of solvent extraction. The solvent extraction method comprises the following steps: grinding a trace rock sample, adding an organic solvent, sealing, soaking, carrying out ultrasonic treatment, and centrifuging to obtain an extract, and the trace amount being less than 1g; carrying out fluorescence quantitative analysis on the extract to determine the oil concentration; when the oil concentration of the extract is greater than 0.01 mg/L, repeating the extraction step; otherwise, ending extraction to obtain the hydrocarbon substances. The solvent extraction method provided by the invention fills the blank of organic solvent extraction of hydrocarbon substances in a trace sample, can realize accurate quantification of the oil content of shale and analysis of the composition of the hydrocarbon substances in the shale by combining extract pyrolysis analysis and extraction liquid chromatographic analysis, and powerfully supports current shale oil exploration evaluation. The method has the advantages of simple operation, batch treatment, less time consumption, less organic solvent consumption and environmental friendliness.
