苏里格气田苏120井区盒_8段储层特征研究

综合利用剖面观察、岩心薄片、铸体薄片、扫描电镜、压汞测定等方法,对苏里格气田苏120区块盒8段沉积微相及砂体展布特征、储层岩石学特征、储集特征和储层物性特征以及成岩作用进行了深入系统的研究。结果表明:苏里格气田苏120区块盒8段储层属低孔低渗储层;储层岩性以岩屑石英砂岩、石英砂岩为主;研究区储层孔隙空间主要有岩屑溶孔和晶间孔;成岩作用对该储层物性及储集空间有着重大影响作用。通过对该区储层特征的研究,可为下一步勘探开发提供地质依据。

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.
