摘要：

在调研我国陆相砂岩油田开发现状的基础上,从中高渗透油田、低渗透油田及断块油田角度出发,总结并归纳不同类型油田面临的开发现状,制定有效开发战略对策.结果表明:中高渗透油田开发应立足于井网加密与三次采油相结合;低渗透油田应以CO2驱油,辅助微生物驱油的开发对策;断块油田应开展气驱、微生物驱和热采研究与试验的战略对策.该研究成果对中国陆相砂岩油田特高含水期的有效开发具有指导意义和借鉴价值.

Abstract: Based on the situation of continental sandstone oil fields in high water cut stage,a study carried out on the development situation,problems and strategic countermeasures of the continental sandstone oilfields in high water cut period.On the basis of the comprehensive research on Chinese continental sandstone oilfields development status,from three angels of middle-high permeability oilfield,low permeability oilfield and fault block oil field,this paper summarizes the development problems and effective development strategy countermeasures for different types of oil fields.The results are as follows: For middle-high permeability oilfields,putting forward the proposal that well pattern thickening should be in combination with tertiary recovery:in low permeability reservoir,it should be mainly depending on CO2flooding,microbial flooding as supplement,gas flooding,microbial flooding and thermal recovery experiments should be suggested in the fault block oilfields.The research results are of important guiding significance and reference value for the effective development of extra high water cut stage for continental sandstone oil fields in China.
