摘要
在长期水驱的影响下,地层孔隙、孔喉、孔道逐步扩大,油田出现了严重的水驱"短路"现象,常规调剖堵水技术已不能满足现场需求,近些年来报道并发展了深调技术(深部液流转向技术),它对油层改善效果明显。分析了国内外深部调剖技术的研究进展,旨在充分认识油藏现状的基础上,实现对高含水油藏和聚合物驱油藏深部液流的转向,从而提高水和聚合物的驱油能力。
Under the influence of long-term water flooding,the formation porosity,pore throat,widening channel,created serious of water drive oilfield ＂short circuit＂phenomenon,conventional profile control water plugging technology already can not meet production requirements,as result,an in-depth profile control technology is developed in recent years.Tn this paper,technologies of in-depth profile control at home and abroad is widely analyzed.A complete studies of in-depth profile control and polymer flooding should be developed based on the sufficient understanding of reservoir status,should be interposed and fluids diverted,and oil displacement efficiency of water flooding and polymer flooding would be improved.
