摘　　要：油藏评价是实现勘探开发一体化系统工程的枢纽环节与核心载体。以区域沉积构造背景、宏观成藏富集规律及开发生产动态效果为基础,从高分辨率层序地层学、储层地质学和成藏动力学等多学科交叉角度对鄂尔多斯盆地姬塬地区上三叠统延长组岩性油藏开展了系统的综合性评价。结果表明,储层非均质性与流动单元的精细刻画及成岩演化与油气充注的匹配关系、能量场形成演化的成藏效应与裂缝输导体的输导性能、流体运移路径的三维追踪与油气聚集的圈闭类型等因素是控制研究区岩性油藏富集空间与成藏规模的主要问题,亦是产能预测与优选开发油藏快速评价体系中的重点参数指标。Reservoir evaluation is an important hinge and carrier for carrying out systems engineering integration of petroleum exploration and development.By using the accumulation dynamics,reservoir geology and high-resolution sequence stratigraphy,the lithologic reservoirs are systemically analyzed and evaluated for Upper Triassic Yanchang Formation in Ordos Basin,based on the regional tectonic-sedimentary setting,general accumulation rule and production dynamic effect.The results show that these problems are not only the controlling factors for petroleum distribution and reservoirs scale but also the necessarily rapid evaluation indices for production forecasting and development program choosing the lithologic reservoirs in this region.These factors are the reservoir heterogeneity and flow units division,the match relation of fluid charging histories and diagenetic evolution,the mechanisms of energy fields development and the migrating capability of recessive conduit,3-dimensional tracing migration pathways and trapping space types.
