摘要
根据试油试采资料和油井压裂前后的产能变化 ,分别设计了反九点和五点面积注采井网 ,利用油藏数值模拟方法分析了边水能量、注水时机、注采比和采油速度对两种井网开发效果的影响。结果表明 ,五点井网布井方案优于反九点井网布井方案。注水井应平行于裂缝伸展方向排列 ,与边水供给方向一致。油井配产量平均为 8.6t/d ,采油速度为 1% ;断块投产 1年左右应及时注水 ,且注采比保持为 1才能保证稳产高产。
The inverse nine spot and five spot well patterns were designed according to the test data of oil production and productivity before and after hydraulic fracturing. A reservoir numerical simulation model is used to determine the effects of water basin volume, injection production ratio and production rate on the two well patterns. The five spot pattern is prior to the nine spot pattern. The injection wells should be arranged in parallel to the fractures and in the inversion direction of edge water. Water injection should be operated after the oil well is performed for one year. The suitable operation project should be the unity of injetion production rate ( R \%IP ) with 1% production rate.
