随着科技的进步,我国的石油勘探开发技术也在不断的完善和发展。目前,新开发的地质中,低渗透油藏占的比例越来越大,大约占到了70%左右。低渗透油藏主要的开发方式就是注水开发,而低渗透油藏注水开发又存在一定的问题。注水井启动的压力高、地层和注水压力上升快,吸水能力差等。本文主要是针对这些存在的问题展开研究 With the progress of science and technology, China’s oil exploration and development technology is also constantly improving and developing. At present, the newly developed geology, the proportion of low permeability reservoirs account for more and more, accounting for about 70%. The main development method of low-permeability reservoirs is waterflooding, while there are some problems in the development of low-permeability reservoirs. Water injection wells start high pressure, stratification and injection pressure rise faster, poor water absorption and so on. This article mainly focuses on these existing problems
