Research and Application of Cable Modular Cluster Perforating Technology
The cable modular cluster perforating technology is the key technology applied to the development of shale gas horizontal wells.This paper mainly analyzes and summarizes the development status and application structure of the cluster perforating technology at present,studies and compares the layout of detonators and electronic selector switches in gun strings.The current separated structure has a high failure rate when used on site.This article proposes the concept of modular cluster perforation,studies the composition structure and studies the integration form of detonators and electronic selector switches.By integrating electronic selector switches with detonators,the reliability of on-site use is improved.At the same time,the safety structure of electronic selector switches is studied and analyzed.This paper summarizes the main gun string combination forms currently used in China for this technology,which is beneficial for more researchers to choose and use.It also proposes suggestions for future development of wireless controlled detonation modular cluster perforation technology.
