| 摘 要： | 针对四川洛带遂宁组气藏复杂的沉积微相,通过岩相成因单元的识别,采用成因砂体的相控旋回等时对比方法,在微相沉积模式的指导下,建立单井微相数据库。同时,通过常规的变差函数分析控制和约束序贯指示模拟可以建立精细沉积微相模型。但其采用的二点地质统计学得到的确定的变程参数并不能完全体现遂宁组气藏复杂的砂体空间构形。基于此,提出运用高分辨层序地层学研究,在能够反映单个成因砂体纵向演化的精细等时小层内,采用成因砂体空间精细雕刻技术,建立精细沉积微相模型,并在相控基础上结合序贯高斯模拟方法建立储层参数模型,从而极大地降低建模过程中的不确定性和随机性。其成果在用于砂体及其储集物性展布特征和变化规律研究、主河道确定和预测、地质概率储量计算等方面可以获得较好的应用效果。

| Abstract: | Being aimed at the complicated sedimentary environment of the Upper Jurassic Suining Formation in the Luodai gas fields of Sichuan Basin,the accurate and dependable database of microfacies is got by identifying the origin lithofacies unit and the facies-controlled isochronous correlation of the cycle sequences of an origin sand body under the guide of the sedimentary patterns.However,the determined range parameter from two-point geostatistic theory can not completely embody the complicated spatial configura... |
