摘　　要：剩余油分布规律研究是油田后续滚动开发的基础,数值模拟的精度高低是分析剩余油分布规律的关键。龙虎泡油田是岩性和构造控制下的低渗透油藏,为浅湖相和三角洲前缘相沉积。针对龙虎泡油田主体区块的地质、构造及沉积特征,在数值模拟历史拟合过程中,采用虚拟井技术、PETRE-RE技术、分割与整合技术、分类拟合技术及分相带与分阶段相渗标定等,对主体区块储量进行拟合,单井拟合精度达到了91.6%,确保了其误差在5%以内,最终得到了龙虎泡油田平面和纵向上的剩余油分布规律,更好地指导了油田后期开发。Residual oil distribution study is the basis of subsequent rolling development of oilfield, and the accuracy of numerical simulation is the key for the analysis of residual oil distribution rule. Longhupao Oilfield is low permeability reservoirs controlled by lithology and structure, belonging to coastal shallow-lake facies and delta front deposition. Aimed at the geology, structure and sedimentary characteristics of Longhupao Oilfield, the reserves was fitted with virtual wells technology, PETREL-RE technology, segmentation and integration technology, partition fitting technology, endpoint calibration in stages and phase spreads. The fitting precision reached 91.6%, and the block geological reserves fitted precision error is lower than 5%. The residual distribution rule in planeand vertical was obtained, which can guide the further development of oilfield.
