Abstract

The invention relates to a method for representation and factor recognition of common carbonate rock diagenesis fabric features. The method includes the following steps that rock cores are observed, sampled and flaked; the diagenesis fabric types and periods of samples are determined under a microscope, and a petrology chart is formed; single-period diagenesis fabric is sampled or flakes are ground; multiple kinds of geochemical analysis is conducted on the diagenesis fabric, and then geochemical data are generated; the geochemical data are collected, a chart is drawn according to the data, and a geochemical chart is formed; based on the geological backgrounds of the samples, the petrology chart and the geochemical chart of the samples are comprehensively analyzed, and then the factors of the samples are reasonably explained. According to the method, the single-period diagenesis fabric serves as an experimental analysis unit, multiple kinds of experimental analysis is conducted on the single-period diagenesis fabric, and the method has the advantages that blindness of traditional total rock analysis is avoided, the purpose that carbonate rock diagenesis is objectively represented is achieved, and the result obtained based on petrology data and multiple geochemical data is more reliable.

Description

technical field

[0001] The invention relates to a characteristic characterization and genetic identification method of common diagenetic fabrics of carbonate rocks, belonging to the technical field of rock analysis. Background technique

[0002] The diagenetic environment of carbonate rocks is closely related to the formation and development of reservoirs, and the identification of diagenetic environments is of great significance to the evaluation and prediction of carbonate rock reservoirs. At present, there is no mature carbonate rock diagenetic environment identification technology at home and abroad. For many years, people have mainly interpreted carbonate rock diagenetic environment based on petrological and geochemical methods. This is also the only way to solve this problem. However, the traditional There are disadvantages in practical application of petrological and geochemical methods. First, due to the ancient age of carbonate rocks in my country, the characterist...
