摘　　要：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 control the bottom water coning and the oil production rate declining and to enhance oil recovery of Donghe sandstone reservoirs in Hadexun oilfield, the affects of oil/water viscosity ratio, density difference between oil and water, reservoir thickness, interbedded layers~ development and placement in reservoirs, standoff, perforated location and horizontal segment length of the horizontal wells on appropriate production rate for horizontal wells of the sandstone reservoirs were studied and analyzed with numerical simulation. The results indicated that the standoff, interbedded layers~ development and placement in reservoirs, oil/water viscosity ratio are critical parameters that affect the appropriate production rate for horizontal wells of Donghe sandstone reservoirs in Hadexun oilfield. Put forward a reasonable strategy for appropriate production rate for horizontal wells of the sandstone reservoirs.
