Research on the characteristics of He-8 reservoir of permian in Sulige gas field Su120 bore field

Sulige gas field Su120 bore field were systematically studied on sedimentary microfacies and petrology characteristics, reservoir characteristics, reservoir physical property characteristics and diagenesis by comprehensive utilization of sections observation, core observation, scanning electron microscopy and mercury measurement methods etc. The result shows that the reservoir of He-8 reservoir in Sulige gas field Su120 bore field is a low, super low porosity and low permeability reservoir. The reservoir lithology are mainly lithic quartz sandstone and quartz sandstone. The reservoir pore space are mainly lithic pore and intergranular pore. Diagenesis has a significant impact on the role of the reservoir properties and reservoir space.Research on the reservoir characteristics of the area can provide a geological basis for the next step of exploration and development.
