摘　　要：精细油藏描述研究是油田开发基础工作之一,其研究精度的不断提高,极大地促进了油田开发水平的提升。“十二五”和“十三五”期间,中国石油精细油藏描述研究针对多层砂岩油藏、复杂断块油藏、低渗透砂岩油藏、砾岩油藏、稠油油藏、特殊岩性油藏分别开展了技术攻关,形成了不同类型油藏配套技术系列。为了支撑剩余经济可采储量(SEC)储采平衡、老油田“压舱石”、采收率再提高、页岩油革命等“四大工程”,系统梳理中国石油精细油藏描述研究在5个方面的最新进展,分别是井震结合构造精细解释技术实现低级序断层定量描述,基于储层构型研究的单砂体刻画技术实现米级砂体描述预测,室内实验、数字岩心、物理模拟和数值模拟等方法技术实现综合剩余油表征,精细油藏描述成果平台建设实现研究过程协同共享和成果规范化存储管理,建章立制制定系列标准规范实现精细油藏描述研究规范化。通过系统总结精细油藏描述存在的8个方面问题,提出精细油藏描述的发展方向。The study of fine reservoir description is one of the basic work of oilfield development,and the continuous improvement of its research accuracy greatly promotes the improvement of oilfield development level.During the"12th Five-Year Plan"and"13th Five-Year Plan"period,CNP fine reservoir description research carried out technical research on multi-layer sandstone reservoir,complex fault block reservoir,low permeability sandstone reservoir,conglomerate reservoir,heavy oil reservoir and special lithology reservoir.A series of supporting technologies for different types of reservoir have been formed.There are five recent advances in the study of fine reservoir description in PetroChina.The quantitative description of lower sequence faults is realized by combining well earthquake with fine structural interpretation technique.The single sand body characterization technique based on reservoir configuration study realizes the description and prediction of meter-level sand body.The remaining oil was characterized by laboratory experiment,digital core,physical simulation and numerical simulation.The construction of fine reservoir description results platform realizes collaborative sharing of research process and standardized storage management of results.A series of standards have been formulated to standardize the study of fine reservoir description.By systematically summarizing 8 problems existing in fine reservoir description,8 development directions of fine reservoir description in the future are put forward.
