摘　　要：宋芳屯油田芳135区块内发育着大量的断层,导致葡萄花油层的油水分布较为复杂。基于试油试采、油水井生产及地质静态等资料进一步研究,得出了平面和垂向上的油水分布规律:油水分布在平面上主要分布在区块的中部和东部地区,该区域分布较多的断层,受构造控制形成大范围的断层遮挡和断层岩性油藏;在垂向上,油水分布具有明显的分异特征,以PI2_1—PI3小层为主要的含油层位。油水分布的主控因素包括:平面油水分布具有分带的特征,油水的平面分布受构造控制明显;水下分流河道沉积微相为葡萄花油层的优质储层,而葡萄花水层主要分布于薄层席状砂中;断层与砂体高角度相交的匹配样式对控油最有利。研究结果可为大庆油田采油八厂宋芳屯芳135区块的后续勘探开发和有利区块的预测提供地质依据。There are a lot of faults in Fang135 area of Songfangtun oilefield,so the area has complex oil-water distribution. Through the analysis of oil production test date,means of production and static conditions,the laws of oil-water distribution in the lane and vertical direction were obtained： the oil-rich zone of the plane are mainly in the middle and the east,and there exist many faults. Controlled by structures,due to the large number of distributed fault,which leads to the oil and gas are tectonic units,under the control of the structure is more obvious. It is mainly rich in the payer Pu I2_1-Pu I3. This article explore the main controlling factors of oil-water distribution in this region： tectonic units make oil-water distribution into belts that the east and west; under the sedimentary background of fan delta underwater distributor channel facies,the channel sedimentary sand bodies is the high-quality reservoirs in the Putaohua reservoir. High angle between fault and sand body intersecting matching style best for containment. The results of the study will provide favorable geological basis for exploration and development in the future.
