Abstract

Embodiments of the invention disclose a dolomite karst reservoir genesis identification method and apparatus. The method comprises: establishing a correspondence relationship between a karst reservoir genesis and a dolomite cathodoluminescence feature; obtaining to-be-identified dolomite; performing cathodoluminescence analysis on the dolomite to obtain the dolomite cathodoluminescence feature; and based on the dolomite cathodoluminescence feature, obtaining the dolomite karst reservoir genesis according to the correspondence relationship between the karst reservoir genesis and the dolomite cathodoluminescence feature. According to the method and the apparatus provided by the embodiments of the invention, the type of the dolomite karst reservoir genesis can be quickly identified.

Description

technical field [0001] The present application relates to the technical field of oil and gas exploration, in particular to a method and device for identifying the origin of dolomite karst reservoirs. Background technique [0002] Dolomite reservoirs play an important role in carbonate oil and gas exploration. According to statistics, dolomite accounts for more than half of the oil and gas reservoirs related to carbonate rocks in the world. Especially in deep carbonate oil and gas reservoirs, dolomite accounts for a larger proportion. Due to the age of dolomite reservoirs, large burial depth, high degree of diagenetic evolution, rich and diverse pore types, and strong heterogeneity, research on reservoir genesis lags behind, restricting the evaluation of this type of reservoir. [0003] Traditional research on dolomite mostly focuses on the mechanism of dolomitization. It is believed that the volume reduction effect in the dolomitization process can produce pores. Therefore...
