摘　　要：由于常规压裂技术无法实现裸眼完井水平井长水平段的压裂,严重制约了油田非常规油气资源的大规模开发,为此,进行了管外封投球滑套压裂技术研究。研制了K342-142压裂封隔器、PS70-140压差滑套、BS70-140投球滑套、QZ-130坐封球座等一系列工具,形成适用于河南油田的多级分段压裂工艺管柱,适合致密砂岩压裂,满足了油田快速开发非常规资源的需要。Due to the fact the conventional fracturing technology cannot fracture the long horizontal section in open-hole completed horizontal well, which severely restricts the large-scale development of unconventional oil and gas, research was carried out on fractur-ing technology by ball dropping sliding sleeve outside the casing. A series of tools like K342-142 fracturing packer, PS70-140 pressure difference sliding sleeve, BS70-140 ball dropping sliding sleeve and QZ-130 setting ball seat were developed, and a multi-stage fractur-ing technical string applicable to He’nan Oilifeld was generated, which is suitable for tight sandstone fracturing and satisifes the need for rapid development of unconventional resources.
