摘　　要：针对史100断块史103井区的具体特点,从体积波及系数、采收率、经济效益及开发实践等方面对加密调整可行性进行了充分论证,在此基础上确定了合理的井距和井网密度。结合井网加密方式和注水方向性研究,利用数值模拟优选了加密调整方案。矿场阶段实施后,水驱开发效果得到明显改善,为同类油藏的调整提供了行之有效的途径。According to the characteristics of S103 well field in S100 fault block,this paper demonstrates the feasibility of infilling adjustment in respect of sweep efficiency,recovery,economic benefit and development practice,and determines optimum well spacing and density.Combining with infilling pattern and water injection direction,it optimizes infilling adjustment plan using numerical simulation.After pilot test,water flooding development effect is improved.Daily oil production increases by 40.5t/d,natural decrease rate declines from 8.2% to 3.3%,recoverable reserves increase by 5.2×10~4t,and water flooded recovery increases from 23.6% to 24.9%.
