国内在低渗透石油资源的开采过程中因为低渗透油田有着较低的渗透率,同时油田的孔喉也比较细小而且对受到的压力非常的敏感,所以低渗透的石油资源相比较于高渗透的石油资源其渗流的规律比较特殊并且具有油气田的开发特点。针对石油资源特点的注采系统对开采石油资源的工作效率上有很大的影响,大大减少了石油产量下降的情况并且使开采油井的见水时间得到推迟从而大大提高了石油资源的开采效率。本文通过对石油资源工程方法的运用对低渗透油田的注采系统进行了相关研究,同时根据实际数据对注采系统的几种方法进行了比较。最后通过计算了解到实际的石油资源拥有较低的地层压力,并且开采石油的速度和注采比也不是很高。
Domestic low-permeability oil resources in the mining process because of low permeability oilfield has a lower permeability, while the oil and gas pore throat is relatively small and very sensitive to the pressure, so low-permeability petroleum resources compared to the high permeability The law of percolation of petroleum resources is rather special and has the characteristics of oil and gas development. The injection-production system which is aimed at the characteristics of petroleum resources greatly affects the working efficiency of the exploitation of petroleum resources, greatly reduces the decline of oil production and delays the seepage time of the production wells, which greatly improves the efficiency of petroleum resource exploitation. In this paper, the research on the injection-production system of low-permeability oilfield is made through the application of petroleum resource engineering method, and several methods of injection-production system are compared according to the actual data. Finally, we know through calculation that the actual oil resources have lower formation pressure and that the rate of oil production and the injection-production ratio are not very high.
