目前,国内各大油田虽然均采取了不同的开采方式,例如:聚合物驱、化学驱等,但水驱油仍然是主要的开采方式,水驱技术已经发展到相当高的水平,超前注水开能合理地补充地层能量,提高地层压力,防止储层渗流能力下降,从而提高油井生产能力并减小产量递减速度。为了解低渗、特低渗透欠压油藏的有效开发方式,总结开发经验,总结提高采收率的方法。本文选择某油田某一实验区为研究对象,对其地层物性进行了全面分析,希望能够对渗透率较低油田的开发起到一定的借鉴作用。
At present, although major oilfields all adopt different exploitation methods such as polymer flooding and chemical flooding, water flooding is still the main mode of exploitation. Water flooding technology has been developed to a very high level. It can reasonably replenish formation energy, enhance formation pressure and prevent reservoir seepage ability from decreasing, thereby increasing oil well productivity and decreasing production decline rate. In order to understand the effective development methods of low-permeability and ultra-low-pressure under-pressure reservoirs, sum up the development experience and summarize the methods of increasing oil recovery. In this paper, a certain experimental area of a certain oilfield is selected as the research object, and a comprehensive analysis of its physical properties is made. It is hoped that it can be used as a reference for the development of oilfields with lower permeability.
