A method for characterizing oil content state of oil shale in mining area

Abstract

The invention discloses a method for characterizing the oil content state of oil shale in a mining area, which is characterized in that the method includes: classifying the oil content of the oil shale according to the distribution probability of the oil content of the oil shale, wherein, The distribution probability value of the specific oil shale oil content value is the probability value that the oil shale oil content value of all mining areas in the resource area is greater than or equal to the said oil shale oil content value; determine the oil shale oil content rate of the current mining area according to the measured data Level: using the oil content level of the oil shale in the current mining area to characterize the oil content state of the oil shale in the current mining area. The method of the invention classifies the oil content of the oil shale through data statistical analysis, normalization processing and equal frequency analysis, thereby characterizing the state of the oil content of the oil shale in the mining area. Compared with the prior art, the method of the present invention not only has better scientificity and rationality, but also has simpler operation, more reasonable results and wider applicability.

Description

technical field [0001] The invention relates to the field of geological development, in particular to a method for characterizing the oil content state of oil shale in a mining area. Background technique [0002] In the process of geological exploration and development, a variety of geological parameters are used to measure the resource status of mining areas, such as oil content, abundance of oil and gas resources, and amount of oil and gas resources. In particular, in the exploitation of oil shale resources, the oil content of oil shale is an important parameter to characterize the quality of oil shale, and an important indicator to evaluate whether oil shale resources can be economically utilized, and has the effect of one vote veto. Specifically, the oil content of oil shale refers to the weight percentage of oil shale oil in oil shale, which indicates the oil production rate of rock during low-temperature carbonization, that is, oil shale is heated from 300°C to 600°C,...

AI Technical Summary

Problems solved by technology

[0005] However, with the further development of oil and gas exploration and production technology, the rough classification method directly based on the oil content of oil shale in the existing technology can no longer meet the needs of continuous data analysis and refined oil and gas exploration and development.
