摘　　要：目前,川东地区礁滩相地层已形成一套相对完整的储层测井综合评价方法,在油气勘探工作中发挥了重要作用。红星地区茅口组储层呈非均质性且特征非常明显,储层的储集参数、流体性质及储层有效性测井评价技术面临新的挑战。以川东红星地区建南区块茅口组茅二段-茅三段碳酸盐岩为研究对象,基于“四性关系”研究,明确储层岩性、电性、物性、含气性与裂缝发育特征,从而建立适合于茅二段-茅三段碳酸盐岩储层评价标准。该标准能够有效识别储层类型与含气性,并为同类复杂碳酸盐岩储层评价提供参考。At present,a relatively complete comprehensive reservoir logging evaluation method has been developed for the reef-shoal facies formations in the eastern Sichuan Basin,playing an important role in oil and gas exploration.The Maokou Formation reservoir in the Hongxing area exhibits significant heterogeneity and distinctive characteristics,posing new challenges for the logging evaluation of reservoir parameters,fluid properties,and reservoir effectiveness.This study focuses on the Maokou Formation(Member 2 and Member 3)carbonate reservoirs in the Jiannan block of the Hongxing area in eastern Sichuan.Based on the research on the"four-property relationship"(lithology,electrical properties,physical properties,and gas-bearing properties),the study clarifies the characteristics of reservoir lithology,electrical responses,porosity and permeability,gas-bearing properties,and fracture development.Accordingly,a reservoir evaluation standard suitable for the carbonate reservoirs of Member 2 and Member 3 of the Maokou Formation is established.This standard effectively identifies reservoir types and gas-bearing properties,providing a reference for the evaluation of similarly complex carbonate reservoirs.
