摘　　要： 在油田开发中后期,为建立更为准确的地质模型指导后期剩余油调整挖潜,提出一种井震动静四位一体储层建模方法。该方法首先通过井震结合确定砂体分布趋势,然后通过静动结合分析砂体连通性,以此得到多种模型约束条件来建立初始地质模型,通过对初始地质模型开展油藏数值模拟历史拟合,对拟合结果进行分析来指导地质认识及地质模型的更新,最终实现地质模型中对砂体分布范围及井间连通性的精细表征。在渤海Q油田河流相储层,利用该方法建立的模型开展数值模拟,有效提高了单井历史拟合精度及井间剩余油分布预测精度。 A method was proposed to build a more accurate geological model guiding the recovery of the remaining oil in the middle or later period of the oilfield development. Firstly, sandbody distribution trend was analyzed by well and seismic data, and then through the analysis of static and dynamic data, sand body connectivity was clear. On the basis of the above results, an initial geo- logical model was built, and then the history matching was done with the model. Then the initial geological model was updated through the analysis of history matching results. At last, the sand body distribution range and connectivity between wells were char- aeterized precisely in the new model. A model of fluvial facies reservoir in Q oilfield of Bohai area was established by this method, and then the model were used by reservoir numerical simulation. The result shows that the accuracy of the history matching and the prediction accuracy of remaining oil distribution were greatly improved.
