Reservoir Characteristics and Dominant Factors of Jiamuhe Formation in Xiaoguai Area of Junggar Basin
详细信息   
摘要
The reservoir of Jiamuhe Formation in Xiaoguai area belongs to the low porosity and low permeability reservoir.In order to determine the domain factors of the reservoir,the sedimentary characteristic,reservoir space,physical characteristic and diagenesis are studied.The result shows that lithology (facies) is the fundamental condition to control the reservoir development.The master fractures caused by the tectonic movement are conducive to oil and gas’s migration and accumulation,while strengthening the development of cracks in the reservoir.Besides,corrosion of diagenesis improves the permeability of the reservoir in the region effectively.
