吐哈盆地红台地区凝析气藏测井解释与储层参数评价

常规油层和气层的解释理论和技术日趋完善，但关于凝析气藏的测井解释理论基础还相对薄弱。以吐哈盆地红台地区为例，对凝析气层的电性特征进行了分析，认为凝析气层在三孔隙度测井曲线幅度和深、浅、微电阻率等方面存在差异。针对研究区凝析气藏特点，在关键井“四性”关系研究的基础上，建立了储层参数测井解释模型，采用交汇图技术和实际试油、试气资料相结合的方法，对研究区目的层常规测井储集层的分类标准进行了分析,并结合红台气田七克台组和三间房组凝析气藏特点，建立了研究区储层参数分类评价标准，依据该标准将红台地区储集层划分为4类。

Log Interpretation and Reservoir Parameter Evaluation onCondensate Gas Reservoirs in Hongtai Area, Tuha Basin

The log interpretation theory and technique about conventional oil and gas reservoirs are gradually becoming more and more feasible at home and abroad, but the research on condensate gas reservoirs is still weak. Firstly, with the analysis of electric characteristics of a condensate gas reservoir, we find that there are some differences between Tri-porosity logging amplitude, Deep Investigation Laterolog, Shallow Investigation Laterolog, and Microlaterolog, etc; secondly, in view of the feature of the condensate gas reservoir, the log interpretation model is built on the basis of the correlation of four reservoir parameters, and the reservoir grade scale is completed using conventional logging techniques combined with cross plot technique and the result of well testing; finally, according to the feature of Qiketai Formation and Sanjianfang Formation in the Hongtai oil field, we set up the reservoir classification criteria and divide the reservoir parameters into four types.
