为了有效抑制哈得逊东河砂岩油藏外围底水锥进和产量递减、提高原油采收率,利用油藏数值模拟技术分析了油水粘度比、油水密度差、油层厚度、油层中夹层的发育程度及位置、水平井井轨迹及射孔段位置、水平井水平段长度等因素对该油藏外围水平井合理配产的影响。研究表明,影响该油藏外围水平井合理配产的主要因素是水平井避水高度、夹层发育程度及位置和油水粘度比,并提出了该油藏外围单井合理配产的对策。
In order to effectively control the bottom water coning and production decline in the peripheral area of the Hudson Donghe sandstone reservoir and increase the oil recovery rate, the oil-water viscosity ratio, oil-water density difference, reservoir thickness, interlayer development in the oil layer were analyzed using reservoir numerical simulation The degree and position of horizontal well, the trajectory of horizontal well, the position of perforation section and the length of horizontal section of horizontal well etc. On the rational allocation of horizontal wells in the periphery of the reservoir. The results show that the main factors influencing rational allocation of horizontal wells in peripheral reservoirs are the horizontal well water-avoidance height, interlayer development degree and location and oil-water viscosity ratio, and the countermeasures for rational allocation of single well in the periphery of the reservoir are proposed.
