利用带有 0 3～ 0 8mm人工裂缝的三维两相油藏数值模拟模型、经济评价模型和整体优化软件 ,对五点法和反九点法井网中人工裂缝与井排夹角为 0 °和 45 °的油藏开采进行动态模拟。根据油藏参数和开发要求实现对井网、压裂、注入、采出参数的整体优化 ,进行多因素、多目标、多方案的优化决策。压裂、注水、采油整体优化方法在大庆朝阳沟油田长 42 1 0区块应用 ,取得了较好的效果。
Using the numerical simulation model of three-dimensional two-phase reservoir with 0 3 ~ 0 8mm artificial fractures, economic evaluation model and overall optimization software, the angle between artificial fractures and well row in the five-well method and the anti-nine-point well pattern is 0 ° And 45 ° of reservoir exploration for dynamic simulation. According to the reservoir parameters and development requirements, the overall optimization of well pattern, fracturing, injection and production parameters can be made, and multi-factor, multi-objective and multi-program optimization decisions can be made. The overall optimization methods of fracturing, water injection and oil recovery have been applied in Block 4210 in Chaoyanggou Oilfield, Daqing, and have achieved good results.
