摘　　要：针对低渗透油田投产开发后,地层压力保持水平低,油井产量递减速度快的矛盾,对原开发井网进行适时的调整及时补充地层能量是十分必要的。应用数值模拟技术对敖南油田试验区注采系统调整方案适应性进行研究,指出,试验区需要在油水井对应压裂的前提下进行合理地注采系统调整,五点法井网转注为最佳方案,同时也提出了低渗透油田合理的转注时机以及调整方案优选原则,在经济有效的基础上最大程度地提高低渗透油田的采收率。After low permeability oilfield puts into production, the formation pressure is low, and the output of oil well is decreasing rapidly. Therefore, it is necessary to adjust the original development well pattern to supplement the formation energy in time. The adaptability of the injection-production system in the test area of Aonan oilfield is studied using numerical simulation technology, it is held that the injection-production system in the test area must be reasonably adjusted under the premise of corresponding fracturing of oil and water injection wells, and five-point well pattern is the best well pattern scheme. At the same time, reasonable water injection timing of low permeability oilfield and the principle for adjusting injection-production system are put forward, that is, improving the recovery rate of low permeability oilfield to the greatest extent.
