低渗透油藏地质特征与开发对策分析

Analysis of geological characteristics and development countermeasures of low permeability reservoir

针对低渗透油藏的开发问题,首先对低渗透油藏的地质特征进行简单分析,在此基础上,对低渗透油藏开发对策进行研究,为推动我国低渗透油藏开发领域的进一步发展奠定基础。研究表明:低渗透油藏主要具有渗透率低、物性差、连续性差以及砂体发育不完全等多种类型的特征,需要从强化地质调研、注重技术提升、多技术联动、引进新型技术以及井网密度合理设计等多个角度出发,采取多种类型的措施,以此提高低渗透油藏的开发质量。

In view of the development of low-permeability reservoirs,this study first briefly analyzes the geological characteristics of low-permeability reservoirs,and then studies the development strategies of lowpermeability reservoirs to lay a foundation for further development of low-permeability reservoir development in China.The research shows that low permeability reservoirs are characterized by low permeability,poor physical properties,poor continuity and incomplete sand body development.It is necessary to take various types of measures to improve the development quality of low permeability reservoirs from the perspectives of strengthening geological investigation,focusing on technology improvement,multi-technology linkage,introducing new technologies and reasonable design of well pattern density.
