沉积期次控制下的砂砾岩体有效储层地球物理综合预测
|
摘要
东营北带砂砾岩体具有低孔低渗、非均质性强的储集特点,有效储层空间变化快,导致滚动探井钻探效果差,储量难以落实。从沉积期次精细划分出发,结合研究区实际地质情况,应用随机地震反演、物性预测、流体敏感属性分析等地球物理技术,分别对单期次砂砾岩体进行相带展布、孔隙度平面分布预测及基于S变换吸收衰减属性的流体检测,得出砂砾岩体各期次成藏的有利区和富集区。利用综合预测评价结果,指导井位优化部署和新建产能方案设计,取得了良好的滚动勘探开发效果。
Due to reservoir characteristics of low porosity &permeability and strong heterogeneities of glutenite in the northern of Dongying Sag,the effective reservoirs varies sharply in space,leading to poor results of progressive drillings.We have difficulty in the implementation of reserve scale.By fine division of sedimentary cycles for glutenite,facies distribution prediction,porosity distribution prediction,fluid detection of low frequency absorption and high frequency attenuation attributes based on S transform for a single sedimentary cycle of glutenite are conducted by seismic stochastic inversion,physical property prediction,fluid sensitivity attributes analysis and some other geophysical techniques in the local geological conditions.Finally favorable areas of effective reservoirs distribution about all sedimentary cycles of glutenite are obtained.The integrated prediction results were used for guiding well pattern optimization and new plant scheme design and we achieved favorable rolling E&P results.
