摘要

摘要: 为了系统研究塔河油田碎屑岩油气运聚过程，针对研究区目的层的地质特征，文章采用流径和逾渗综合方法进行油气运聚模拟分析。该方法基于断裂-砂体输导格架来开展油气运聚模拟，首先通过断层的分级、分期研究，结合实际资料形成了断层开启性判别标准，进而建立断层输导格架模型；综合使用压实曲线和孔渗关系，利用相控建模技术建立砂体输导格架模型。在断裂-砂体输导格架基础上开展了油气运聚模拟，模拟结果与现有的油气藏吻合较好，表明流径与逾渗综合法是一种模拟研究区目的层油气运聚过程的有效方法。同时，利用模拟结果，明确了主要目的层的潜力区域，对研究区碎屑岩的勘探部署有重要意义和实际价值。

Abstract: To systematically study the oil-gas migration and accumulation of clastic rocks in the Tahe Oilfield,we carried out the simulation of oil-gas migration and accumulation using the comprehensive method of flow routing and percolation on the basis of the geologic character in the study area. The simulation of oil-gas migration and accumulation based on the fault-sandstone migration pathway system were carried out. Based on the study of fault classification and stages,the criterion of fault opening was formed by combining with the actual data at first,and then the model of fault migration framework was established. Using compaction curves and the relationship between porosity and permeability,we built the sandstone migration framework by facies-controlled modeling technology. The simulated results are in good agreement with that of the discovered hydrocarbon reservoirs. It indicates that the method is valid. We pointed out the potential areas by the simulated result as well. The works in this paper have significance and practical value for the exploration of clastic rocks in the study area.
