为了深入探讨成岩作用对该区储层质量的影响,预测该区有利成岩相,对苏里格气田X井区储层成岩作用特征进行了研究,结果表明,储层为典型煤系地层成岩作用,其主要成岩作用类型为胶结作用和压实作用等。岩相划分为中-粗粒石英岩屑砂岩粒间孔-溶孔成岩相等6种类型。
In order to investigate the effect of diagenesis on the reservoir quality and predict the favorable diagenetic facies in this area, the diagenesis of X-well reservoir in Sulige gas field is studied. The results show that the reservoir is the diagenesis of the typical coal series strata , The main type of diagenesis is cementation and compaction. The lithofacies are divided into six types of intermediate-coarse-grained quartz sandstone intergranular pores and dissolved-diagenetic diagenesis.
