A grading evaluation method of shale oil and gas resources

抄録

Shale is rich in oil and gas resources, but the geological conditions are very complex. The successful exploitation of shale gas resources depends on the geological evaluation of shale gas resources. A classification evaluation method for shale oil and gas resources is introduced in this paper. This method has been patented in China. This method solves the defects and deficiencies of the existing shale oil and gas resources classification evaluation methods, provides a feasible identification method for shale oil and gas resources classification, and can effectively avoid misjudgment in shale oil and gas resources development. This method can save the exploration cost of shale oil and gas resources, has remarkable beneficial effects, and is suitable for application and popularization. The characteristic of this method is that the measured data samples are replaced by random numbers by using multiple parameter index values of oil and gas generation and reservoir conditions, as well as the range of enrichment area and favorable area of parameter index values.
