摘要
根据低渗透油藏开发特点,以某一低渗透油藏为研究对象,假设试验区,建立地质模型,对4种井网型式(即菱形反九点井网、正方形反九点井网、矩形五点井网、直线排状井网)的开发效果,通过数值模拟软件进行模拟计算,最终确定菱形反九点井网为最优井网,并对井网的调整进行了模拟优化研究。
According to the characteristics of low-permeability reservoir development,a low-permeability reservoir was chosen as studying object,a hypothetical experiment was established for a low-permeability zone,a geologic model was established,by which simulated calculation was made on the development effects of 4 well patterns by using numerical simulation software,such as inverted nine-spot pattern,the five-spot rectangle pattern,inverted nine-spot square pattern,row well pattern,they were used for evaluating the simulation results,which indicates that the inverted nine-spot pattern is the optimal one,and evaluating well pattern adjustment means.
