裸眼水平井分段压裂完井用批级压裂滑套的研制

摘要

为提高裸眼水平井分段压裂技术的压裂级数，实现一趟管柱压裂更多段，研制了一种批级压裂滑套。介绍了滑套的工作原理、主要结构的具体设计和计算。%A new sliding sleeve is developed in order to improve the fracturing stages of multi-stage fracturing (MSF) of horizontal bare holes and fracture more sections in one time. The operation principles, the design and calculation of the main structure of the slide sleeve are introduced in this paper.
