摘　　要：依据大庆外围油田地质特点,确定了精细油藏描述的思路,选取开采中、低渗透葡萄花油层的宋芳屯油田芳6区块和开采低、特低渗透的榆树林油田东16区块等作为典型研究区块,在区域沉积背景和构造环境分析的基础上,开展了沉积微相、精细构造、裂缝与地应力、地质建模以及剩余油分布的系统研究,深化了对油藏特征的认识,形成了大庆外围油田不同类型油藏独具特色的分级控制、多学科联合的精细油藏描述配套技术。其研究成果已部分应用和推广到大庆外围油田,取得了良好的经济效益。According to the geologic features of Daqing peripheral oilfields, the refined description method for oil reservoir has been fixed. Taking Fang 6 Block with medium production and low permeability in Putaohua oil layer, Songfangtun Oilfield, and Dong 16 Block with low production and extremely low permeability in Yushulin Oilfield as typical research blocks, based on regional sedimentary background and structural environment analysis, a systematical research on sedimentary microfacies, fine structure, fracture and earth stress, geologic modeling and remaining oil distribution has been carried out , deepening understanding of reservoir＇s features. A hierarchical controlled and multi-discipline refined description technique series of reservoir has been formed to describe different types of reservoirs in Daqing peripheral oilfields. The research results have been partly applied and popularized in peripheral oilfields with favorable economic benefit.
