川东北H井飞仙关组储层物性分析

The Reservoir Characteristic Research of Feixianguan Formation Northeast of Sichuan

对H井岩心、岩石薄片的综合分析,飞仙关组海相碳酸盐岩储层的岩石类型、物性特征进行了研究。飞仙关组是本地区主要储集层段,以白云岩以及泥质灰岩为主。储层主要为飞仙关组二段与飞仙关组一段,岩石类型对储层的物性影响较大,白云岩储集物性优于灰岩物性。

Through the comprehensive analysis of drilling core observation,rock slices of.H wells,the rock type and physical characteristics of marine carbonate reservoir in Feixianguan Formation were studied.The Feixianguan Formation is the main natural reservoir, which mainly dominated by the dolomite and argillaceous limestone.The reservoir is mainly in the second section of the flying fairy and first section.Meanwhile the rock types of reservoir have a great influence on the porosity and permeability of reservoir,and dolomite reservoir physical property is better than that of limestone reservoir.
