开发了一种可固井多入口 (ME) 多级压裂 (MSF) 完井技术，其真实压力等级为 15,000 psi，可用于深层致密气井。该完井系统为此类井中通常使用的 MSF 方法带来了操作和设计改进。完整的论文详细介绍了新系统的开发过程，考虑到了恶劣的井况、其用于在每个阶段创建多个裂缝的 ME 设计，以及它相对于传统裸眼 (OH) MSF 解决方案的优势。
常规 OH-MSF 完井系统包括 OH 封隔器、OH 锚、水力压裂端口和球驱动压裂端口。水泥 ME-MSF 完井系统类似，但不需要封隔器或锚，因为水泥提供了区域隔离。
A cementable multientry (ME) multistage fracturing (MSF) completion technology with a true 15,000‑psi pressure rating was developed for use in deep tight gas wells. The completion system brings operational and design improvements to MSF methods typically used in these types of wells. The complete paper provides details on the development of the novel system, considering the harsh well conditions, its ME design used for creating multiple fractures across each stage, and its advantages over traditional openhole (OH) MSF solutions.
A conventional OH-MSF completion system includes OH packers, OH anchors, hydraulic fracturing ports, and ball-actuated fracturing ports. The cemented ME-MSF completion system is similar, but no packer or anchor is required because zonal isolation is provided by the cement.
