摘　　要：近年来,二叠系长兴组生物礁气藏在四川盆地的海相勘探中屡被发现,其埋藏较深、一般具有高产、高含硫化氢特征,储层多为生物礁白云岩。通过研究长兴组生物礁上覆地层飞仙关组底部地层的厚度变化规律和录井特征,提出了一种在钻井过程中快速预测和识别生物礁储层的录井方法,现场应用简便、符合率高,易于在录井现场推广。In recent years,Permian reef gas reservoirs have been often found in marine exploration in Changxin Formation of Sichuan Basin,it was deeply buried and it generally had the characteristics of high yield and high H2S,reservoirs were of reef dolomites.Through the study of the of reef overlying strata of Feixianguan Formation in the bottom where strata were thickened and the features of mud logging,a logging method is put forward for rapid prediction and identification of reef reservoirs during well drilling,its field application is simple with high coincidence rate,it is easily introduced in logging site.
