低渗透油藏注水开发影响因素及对策研究

Study on Influencing Factors and Countermeasures of Water Injection Development in Low Permeability Reservoir

针对低渗透油藏注水开发问题,首先对注水开发的影响因素进行分析,在此基础上,对低渗透油藏注水开发的措施进行研究,为推动我国低渗透油藏注水开发的进一步发展奠定基础。研究表明:地质因素和开发因素将会对该种类型油藏的注水开发效果产生重要影响,因此,需要引入水平井开发和合注合采两种类型的技术,并采取提高生产压差和合理规划井距两种类型的措施,进而使得低渗透油藏的开发效果得到改善。

In view of the problem of waterflooding development in low permeability reservoirs,this study first analyzes the influencing factors of waterflooding development,and then studies the measures of waterflooding development in low permeability reservoirs,laying a foundation for promoting the further development of waterflooding development in low permeability reservoirs in China.The research shows that geological factors and development factors will have an important impact on the waterflood development effect of this type of reservoir.Therefore,it is necessary to introduce two types of technologies,horizontal well development and combined injection and production,and take two types of measures to increase the production pressure difference and reasonably plan the well spacing,so as to improve the development effect of low permeability reservoirs.
