摘　　要：针对东濮凹陷前梨园洼陷西坡深层低渗透异常高压油藏开发中存在的问题 ,以获得良好的经济效益与开发效果为目标优化设计注采井网 :考虑渗流阻力损耗的地层压力 ,通过数值模拟确定井网密度 ;考虑压裂裂缝对深层低渗透油藏注水开发的影响 ,引入地应力研究成果 ,建立水力压裂油藏模型优化设计注采井网。对 2个深层低渗透新建产能区块的井网和 4个开发单元的注采调整的优化获得显著效果 ,实现了高效注水开发 ,3a累计增产原油 62 .8× 10 4 t。图 4参In order to solve the problem between well pattern thickening and invest increasing, on the base of uniting of benefits and effects, the study uses numerical simulation and hydraulic power fracture model, inducts ground stress research results, at the same time, fully thinks about the influence of fracturing fractures for flooding development, makes optimum design to well pattern density and injection production pattern, forms a series of deeper interval and low permeability reservoirs' well pattern optimizing techniques. The research results have been well used and lead to notable effects in the Qianliyuan sag of Dongpu Oilfield.
