摘要 利用数值模拟方法研究分析了采油速度、油层沉积韵律、垂直水平渗透率比、夹层大小及位置、边底水能量、不同油水粘度比、井距、射开程度、毛管压力等对砂岩底水油藏开采效果的影响,同时对有夹层存在时Kv/Kh值对底水上升速度及形态的影响进行了精细模拟研究。研究表明:影响底水锥进的主要因素是采油速度、垂直水平渗透率比、油水流度比、夹层;砂岩底水油藏底水推进一般以平托为主。文中提出了相应的开发策略。 The effects of production rate,oil formation sedimentary rhythm,ratio of vertical to horizontal permeability,size and position of an impervious break,volume of edge and bottom water ,ratio of oil to water viscosity,well spacing,perforation interval and capillary pressure on the production performace of a sandstone reservoir with bottom water were studied and analyzed with numerical simulation.The bottom water movement with impervious break in different vertical to horizontal permeability ratio were also simulated.The results indicated that the size and position of an impervious break,vertical to horizontal permeability ratio.oil to water mobility ratio and production rate are critical parameters that affect the water coning behavior in sandstone reservoirs with waterdrive.Water coning are not usually formed in sandstone reservoir with bottom water.
