摘要
高温高盐油气藏广泛分布于我国各地。随着油田的不断开采,大部分油田已进入中后期开发阶段,存在着高温高盐环境和油井出水严重的双重问题,导致水驱的纵向波及系数和洗油效率降低,降低原油采收率。常规堵剂的使用已无法满足高温高盐油藏的深度开采。对已经报道的高温高盐调剖堵剂研究现状、堵剂性能及封堵机理先进研究方法进行了整理分类,根据文献调研对今后高温高盐堵剂的研究方向提出了一些建议。
High-temperature and high-salt oil and gas reservoirs are widely distributed throughout China.With the continuous exploitation of oil fields,most oil fields have entered the mid-to-late development stage,and there are dual problems of high temperature and high salt environment and serious oil well effluent,resulting in a reduction in the longitudinal flooding coefficient of water flooding and oil washing efficiency,and lower crude oil recovery.The use of conventional plugging agents has been unable to meet the deep development of high-temperature and high-salt oil reservoirs.The reported research status,performance and advanced research methods of plugging agents for high-temperature and high-salt profile control agents are sorted out,and some suggestions for future research directions for high-temperature and high-salt plugging agents are proposed based on literature research.
