作者杨海波,赵传伟,李毅（2019）在《投球式全通径压裂滑套研制》一文中研究指出：常用的水平井多级分段压裂技术在不下入内管、不进行磨铣作业情况下,难以实现管柱内大通径,不利于后期生产管理,为此,研制了投球式全通径压裂滑套。该滑套采用投球打开方式,无内封隔器、液控管线及专门的开关工具,只需向压裂管柱内投置多个同一尺寸的压裂球即可开启全部滑套,施工工艺简单,效率较高,压裂完后管柱通径大。基于显式动力学分析了压裂球推动内滑套运动过程中,内滑套受力变化以及压裂球坐封过程中可复位球座受力变化。结果表明,内滑套和可复位球座的强度均满足现场压裂施工要求。室内实验表明,内滑套启动压力为7. 6 MPa,压裂滑套打开压力为12. 6 MPa;开关、内滑套、弹簧及可复位球座动作可靠,能完成预定动作。
