摘　　要：民和盆地储层物性较差,普遍具有低孔、低渗或低孔、特低渗的物性特征.通过对上侏罗—下白垩统储集层的沉积相特征、砂体展布、岩石结构类型、物性特征及其影响因素的系统分析,发现高地温场、成岩过程中的压实与胶结作用是造成盆地物性差的主要原因.古埋藏浅、次生孔隙发育、易形成裂缝的环凹陷周缘斜坡带及凹中继承性隆起带储层物性相对有利,为盆地下步勘探目标优选的有利领域.The Upper Jurassic-Lower cretaceous reservoir in Minhe Basin is commonly of low porosity and low permeability or extremely low permeability. This paper presents the analysis of the upper Jurassic-the lower Cretaceous reservoir depositional facies, sandbodies characteristics, petrological characteristics, reservoir properties and the influence Factors .The results indicate that high geothermal fields, the mechanic compaction and later recementation are the key factors that affect reservoir characteristics. The folded structures around the depression associated with shallow buried depth, or the inherited development folded structures associated with the favorable secondary pore and fissure development in the center of the depression are the favorable exploration areas.
