Abstract

Shale gas, which exists in organic-rich shale or mud shale formations primarily in adsorbed or free states, poses significant development challenges due to the low permeability of shale formations. Traditional vertical wells are ineffective for shale gas extraction, making horizontal wells and large-scale hydraulic fracturing essential for efficient development. However, the complexity of the formation can lead to casing deformation, severely impacting the pass capacity of plug and perforation gun strings in the wellbore. This study analyzes the causes of casing deformation and discusses the rapid development of the cluster perforating technology in perforation operations, and discusses the challenges that might encountered during the process of wireline conveying or pumping. The irregular trajectory of horizontal wells and the high dogleg deflecting severity in the deviated sections can cause cluster perforating strings to suddenly get stuck during the downhole process, leading to a sudden increase in pumping pressure, which may result in premature seating of the fracturing bridge plug, or pull-off accidents at the weak point of the wireline. This research aims to improve engineering efficiency and prevent engineering accidents by conducting a pass capacity analysis of the perforating tool string, which is of significant engineering importance for shale gas development.
