Patent number: 11921099Abstract: A method for quantitatively analyzing the reservoir formation of an ultra-deep evaporite-dolomite paragenesis system is performed as follows. A typical drilling core containing the evaporite-dolomite paragenesis system and a field section are observed. The logging data is subjected to single-factor analysis to determine the planar distribution regularity of the ultra-deep evaporite and the dolomite, and the analysis of sedimentary combination pattern and development evolution regularity is performed. The diagenetic system is determined, and the reservoir formation of the evaporite-dolomite paragenesis system is analyzed. Based on the above technical solutions, the property, the evolution path and the reservoir formation of sedimentation-diagenesis fluids in the evaporite-dolomite paragenesis system can be clarified.Type: GrantFiled: July 31, 2023Date of Patent: March 5, 2024Assignee: SOUTHWEST PETROLEUM UNIVERSITYInventors: Fei Huo, Xingzhi Wang, Huaguo Wen, Huiwen Huang, Yunbo Ruan, Liang Li
