摘要
根据焉耆盆地凝析气层的储层条件、油气特征、试油等资料，运用常规测井资料结合固井后补尝中子延迟测井资料，提出了双中子孔隙度差值法，固井后补偿中子延迟测井识别法和双压缩波模量差值法三种凝析气层识别方法。应用效果明显，解释成果经实际资料检验，符合率达80％以上。对类似油气层的评价，该方法具有推广价值。
Based on reservoir conditions, hydrocarbon characteristics and well test data of the condensate gas reservoirs in Yanqi basin,three methods are proposed to use both conventional log data and post-cementing delayed compensated neutron log data to identify condensate gas reservoirs. They include dineutron porosity differential,delayed compensated neutron log recognition after well-cementing and dual compressional wave modulus differential. Real data verification shows that coincidence rate of interpretation results is over 80%.
