摘要
鄂尔多斯盆地下石盒子组盒八段为延川南气田致密砂岩气主力产气层,具有较好的含气性,部分井试气效果良好。通过系统分析单井产能与沉积微相、储层地质特征之间的关系,认为单井产能受沉积微相控制明显,高产井主要分布于水下分流河道沉积微相内。
The 8th member of the Xiashihezi Formation in the Yanchuannan gas field of the Erdos Basin is the main tight sandstone gas reservoir,which has good gas show and gas testing results. A systematic analysis of the relationship between single well productivity,sedimentary facies and reservoir characteristics indicates that,the single well productivity shows a significant control by sedimentary micro-facies,and high-yield wells are predominantly located in the sedimentary micro-facies of distributary channels. Reservoir reconstruction that helps improve the production of tight sand gas reservoir is an important means.
