摘要
民和盆地储层整体物性较差，以低孔低渗-中孔中渗为主，表现为差中有好的特征。总体储层物性不十分理想。综合研究认为武家构造带是巴州凹陷最有利的勘探区带，2003年在巴州凹陷武家鼻隆构造带武家1号构造成功钻探了武1井，测井综合解释气层8．5m／1层，差气层17．8m／2层，气水同层23．7m／1层；在下白垩统大通河组3061～3084．7m井段试油获得低产油气流，日产油0．86m^3，日产气1854m^3。初步计算白垩系大通河组控制石油地质储量210×10^4t。储层的低孔低渗是影响勘探成效的主要因素。该研究从沉积相分析入手，分析巴州凹陷武家构造带储层物性特征，探讨了影响储层发育的主要因素，从而探索有利储层发育区,为勘探生产提供建议。
The comprehensive study indicated that Wujia structural belt of Bazhou sag is the most favorable exploration region in Minhe basin. Well Wul had been drilled successfully at Wujia No. 1 structure in Wujia nose -llke uplift structural belt of Bazhou sag with the active indication of oil and gas in 2003. The controlled reserves in Datonghe group of Cretaceous is counted preliminarily, beginning with the analysis of sedimentary facies, the reservoir physical property characteristics of Wujia structural belt in Bazhou sag is analyzed and the main factors affecting reservoir development are discussed, which provided some suggestions for further exploration of favorable reservoir.
