摘    要:哈得逊东河砂岩油藏外围水平井目前舍水上升较快,产油量出现明显递减.研究以有效抑制外围底水锥进和产量递减、提高原油采收率为目的,通过对比该油藏水平井生产情况与油层中夹层的发育程度及位置、水平井井轨迹和油水粘度比的关系,深入分析了影响该油藏外围水平井合理配产的因素,并利用了油藏数值模拟方法加以论证.研究认为,夹层发育较多、垂向渗透能力相对较低且夹层位于油水界面之上时,水平井配产可较高;水平井位于油层顶部,避水高度较高时,水平井配产可较高;油水粘度比较低时,水平井配产可较高.

关 键 词:哈得逊油田  水平井  合理配产  物性夹层  井轨迹

Abstract:The current water cut of Donghe sandstone reservoirs in Hadexun oilfield has been rising rapidly and the oil production rate of the corresponding wells has declined obviously. In or-der to control the bottom water coning and the oil production rate declining, the affecting factors on appropriate production rate for horizontal wells of the sandstone reservoirs are researched and analyzed. The results indicate that the number, vertical permeability and position of the tight in-terbed layers,well-bore trajectory and oil-water viscosity-ratio are the critical factors affecting the appropriate production rate for horizontal wells in the edging area with bottom water.
Keywords:Hadexun oilfield  horizontal well  production rate  tight interbed  well trajectory
