摘要
结合地质认识将研究区深水浊积复合水道细分为主水道、水道侧缘、天然堤和侧积泥等4类建筑结构要素,应用多点地质统计学与软概率属性协同约束方法随机模拟得到了深水浊积复合水道砂体内部建筑结构,在此基础上对建筑结构要素控制下的储层物性进行了模拟。结果表明,多点地质统计学与软概率属性协同约束方法所得随机模拟结果较好地体现了深水浊积复合水道的空间结构、几何形态以及物性分布特征,可以为油田后期层内挖潜剩余油提供参考依据。
According to geological knowledge in the study area, the compound turbidite channels in deep water can be divided into 4 types of architecture element, i.e. drainage line, lateral channel margin, levee and lateral accretion mud. A coordinated constraint method of multiple-point geostatistics with soft probability attribute was applied to simulate stochastically internal architecture into compound turbidite channel sandbodies in deep water, by which the petrophysical properties controlled by architecture elements were simulated. The results have indicated that the stochastic simulations by the coordinated constraint method of multiple-point geostatistics. with soft probability attribute may more accurately reflect the space structure, geometry and geophysical distribution of compound turbidite channels in deep water, and can provide evidences for exploiting remaining oil within reser voirs during late development of an oilfield.
