摘　　要： 综述了水平井压裂技术在国内外的研究状况 ,重点讨论了压裂水平井的渗流规律、裂缝的优化以及与压裂垂直井的产能比较 .结果表明 :压裂水平井的开发效果和经济效益均优于压裂垂直井 ,其中 ,横向裂缝水平井的生产效果好于纵向裂缝水平井 ,当沿地层裂缝方向的渗透率与沿井筒方向的渗透率之比小于或等于 1时 ,横向裂缝的最佳产能条数为 3～ 5条 . In this paper, the current research of hydraulically fractured horizontal wells in the development of low\|permeability reservoir is overviewed. Some interesting topics, the flow mechanism of the fractured horizontal wells, the optimum of fracturing, and the comparison capabilities between a fractured horizontal well and a vertical well with a vertical fracture, are discussed. The results show that the fractured horizontal wells are better than the vertical wells with vertical fractures in the respect of development efficiency and economy. Especially, the horizontal well with transverse fracture is more preferable to that with longitudinal fracture. When the permeability along the direction of fracture is equal to or less than that along the direction of well bore, the optimum fracture number is 3～5.
