近年来,人们致力于改进多入口多级 压裂(ME MSF)系统,以提高单井内与储层的接触面积。然而,增加压裂段数需要更长的水平段长度。为了克服这些限制,一种新型的ME MSF技术应运而生,它不仅能够实现更长的水平段长度和更高的压裂段数,还能提高增产效率并降低作业风险。该技术采用智能可溶解的压裂针,这些压裂针在激活前能够自动识别特定的套管,从而实现区域隔离。

ME MSF 系统

所描述的 ME MSF 系统经过改进,无需使用射孔枪进行压裂塞的钢丝绳部署,也无需进行连续油管作业。

In recent years, efforts have been made to improve multientry multistage fracturing (ME MSF) systems to increase reservoir contact within a single wellbore. However, longer lateral lengths are required to raise stage counts. An ME MSF technology was developed to address these limitations, enabling longer laterals and increasing stage counts while improving stimulation efficiencies and derisking operations. This technology incorporates intelligent, dissolvable darts that self-identify specific sleeves before activating to provide zonal isolation.

ME MSF System

The described ME MSF system was advanced to eliminate wireline deployment of fracturing plugs with perforation guns and eliminate coiled tubing operations.
