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。
According to the reservoir conditions, oil and gas characteristics and oil testing of condensate gas reservoirs in Yanqi Basin, combined with conventional well logging data and compensated neutron delay logging data after cementing, a dual neutron porosity difference method Three Condensate Gas Recognition Methods After Well Compensation After Neutron Delay Log Recognition and Two Compression Modulus Difference Methods. Application effect is obvious, interpretation of the results of the actual data test, in line with the rate of 80% or more. Similar to the evaluation of oil and gas, this method has the promotion value.
