储层三维地质建模对于定量化油藏描述和预测剩余油饱和度具有重要意义,多种因素对其预测精度有影响。通过对影响建模质量的构造模型和属性模型的研究和分析,得出提高精度的控制因素,结合地质模型与实际储层的储量复检、概率一致性检验、抽稀检验等,确定地质模型建立的合理性。以D油田E块为例,利用分层数据、断层模型、地层接触关系控制,提高沙二段构造模型精度;利用数据平均对比、变差函数物性拟合、序贯高斯物性确定性模拟,改善属性模型的质量与统一性。对比检验结果表明,模型储量拟合较好,相对误差为-1.60%,参数趋势一致性较高,为进一步提高后续模拟的可靠性奠定了基础。
As the basis of quantitative reservoir description and prediction of remaining oil saturation, reservoir three dimensional geological modeling is affected by many factors.Through the research and analysis of the structural model and attribute model which affect the modeling quality,the controlling factors of improving the accuracy are obtained,the rationality of establishing geological model is determined by combining the geological model with the actual reservoir reserve re-examination, probability consistency test and dilution test.Taking Block E of Oilfield D as an example, the accuracy of the structural model of the second section of the sand basin is improved by using stratified data, fault model and stratum contact relationship control; the quality and unity of the attribute model are improved by means of data average comparison, variation function physical property fitting and sequential Gauss physical property deterministic simulation.The comparative test results show that the model reserves fit well with a relative error of -1.60% and the parameter trend is consistent, which lays a foundation for further improving the reliability of subsequent simulation.
