以舍女寺油田N90-10断块储层研究为例,利用岩心、测井、录井、物探等基础地质资料的分析,对舍女寺油田的N90-10区块孔二段油组的地层特征、构造特征、沉积背景对储层物性的影响和控制因素进行研究。通过沉积相分析手段、储层物性综合分析手段和地震属性预测技术研究结果证明,N90-10断块孔二段为三角洲亚相前缘沉积,在沉积相控制下,储层孔隙度、渗透率分布与构造有直接关系,主要受构造高低压实作用,导致孔隙度、渗透率的变化,因此落实区块的构造是寻找油气潜力的首要因素。
Taking the study of the N90-10 fault block reservoir in Shensi Oilfield as an example, the basic geological data of core, logging, logging and geophysical exploration are used to analyze the oil formation of Block Kong90 in block N90-10 of Shensi Oilfield Stratigraphic characteristics, tectonic characteristics, sedimentary background on the reservoir physical properties and control factors. The result of sedimentary facies analysis, synthetic reservoir property analysis and seismic attribute prediction shows that the second member of N90-10 fault block is delta subfacies front deposit. Under the control of sedimentary facies, the porosity and permeability of reservoir The distribution is directly related to tectonics. It is mainly affected by the compaction of the structure, which leads to the change of porosity and permeability. Therefore, the implementation of the tectonic block is the primary factor in the search for hydrocarbon potential.
