随着油田勘探技术的不断发展进步和油田开发技术的进步,国内近几年新勘探发现油田低渗透油田比例不断增加。由于储层物性差,因此投产初期需要采用特定的工艺技术才能够实现经济有效开发,投入开发后需要采用与之对应的注水综合调整技术保持地层能量、减缓产量递减、提高油田采收率。文章结合低渗透油藏特征,对适用于低渗油藏注水开发技术进行了探讨。
With the continuous development of oilfield exploration technology and advances in oilfield development technology, the proportion of low-permeability oilfields discovered by new exploration in recent years in China has been continuously increasing. Due to the poor reservoir properties, it is necessary to adopt specific process technologies in the initial stage of production to achieve economical and effective development. After the projects are put into development, integrated water flooding adjustment techniques should be adopted to maintain formation energy, slow down production decline and increase oil recovery. Combined with the characteristics of low permeability reservoirs, this paper discusses the development of water injection technology suitable for low permeability reservoirs.
