Problems solved by technology

[0003] However, current exploration practice and research often ignore the heterogeneity of rock types in argillaceous source rocks, and usually evaluate a set of source rock formations as a rock type, which will inevitably make the evaluation results difficult to accurately reflect the hydrocarbon source. Overall characteristics and scale of strata series

Abstract

The invention discloses a rock type evaluation method and device for argillaceous hydrocarbon source rock, electronic equipment and a medium. The method comprises the following steps: carrying out mineral composition determination on target hydrocarbon source rock, and determining the rock type of the target hydrocarbon source rock; determining thickness evaluation indexes of hydrocarbon source rocks of different rock types; determining organic matter evaluation indexes of different rock types of hydrocarbon source rocks; obtaining evaluation index plane distribution characteristics of hydrocarbon source rocks of different rock types; and comprehensively evaluating argillaceous hydrocarbon source rocks of different rock types by evaluating index plane distribution characteristics. According to the method, different rock types of argillaceous hydrocarbon source rocks are evaluated respectively, so that a basis is provided for finely depicting the heterogeneity of the rock types of the hydrocarbon source rocks and accurately evaluating the characteristics and the scale of the hydrocarbon source rocks, and further assistance is provided for efficient exploration of oil and gas; the method has a certain application value in the oil exploration and development fields such as oil and gas resource evaluation and unconventional oil and gas exploration.

Description

technical field [0001] The invention relates to the field of petroleum exploration and development, and more specifically, to a rock type evaluation method, device, electronic equipment and medium for argillaceous source rocks. Background technique [0002] A large number of oil and gas exploration practices at home and abroad and theoretical researches on oil and gas hydrocarbon formation and accumulation have shown that the development of high-quality source rocks in the basin is one of the necessary conditions for the formation of large and medium-sized oil and gas fields, and fine evaluation of source rocks is an important means to clarify the exploration potential of the basin one. At present, the evaluation of argillaceous source rocks is mainly done through conventional evaluation indicators of source rocks such as organic matter abundance, organic matter type, organic matter maturity, and source rock development scale. However, source rocks have strong heterogeneity...
