摘要
通过调研综述了国内外水平井注水技术的应用和研究现状。水平井注水技术是一项崭新而有潜力的技术,与直井注水相比,水平井注水可形成线性驱动,推迟注入水突破时间、提高波及效率、改善油藏开发效果。在分析总结水平井注水的注采优势和适用储层条件的基础上,指出了储层物性均质、低渗透、薄储层、稀井网且油水流度比低的稀油油藏更适合水平井注水开发;最后对水平井注水存在的问题和今后的发展趋势进行了探讨。
Domestic and international application and research state of horizontal well injection technology are reviewed through investigation of publications.The technology of horizontal well water injection is a new and promising technology,which can form linear drive,put off water breakthrough,and improve sweep efficiency and recovery compared with vertical injection;homogeneous,low-permeability,thin-layer,sparse-pattern and low-mobility reservoirs are more adapted to water flooding with horizontal wells based on analyzing and summarizing injection and production advantages and applicable conditions of water flooding;finally,existing problems and development trend of water flooding with horizontal wells are studied.
