摘　　要：为深化潜江洼陷盐湖碳酸盐岩测井岩相认识,通过常规测井响应特征分析,基于敏感曲线建立岩相识别图版,有效提高差异性储层方法,并提出硫酸盐含量因子SCF的计算方法,克服埋深不一、敏感曲线受岩石压实程度的影响。潭口地区3口取心井证明与岩性扫描测井结果一致性较强,应用效果良好。This study aims to enhance the understanding of lithology in salt lake carbonate formation logging within the Qianjiang Depression.Through an analysis of conventional logging responses and the building of a lithology identification chart based on sensitive curve analysis,the research effectively improves the differentiation method for reservoirs.Furthermore,a calculation method for the sulfate content factor(SCF)is introduced to address variations in depth and the impact of rock compaction on sensitive curves.The results from three core wells in the Tankou area exhibit strong consistency with lithology scanning logging,indicating a successful and accurate application.
