%X 随着页岩气勘探开发的不断推进，水平井作为页岩气开发的关键核心技术，由于四川威远地区的页岩气藏地质条件复杂，钻井卡钻事故时有发生，造成该地区旋转导向使用率较低，制约了页岩气钻井提速提效。通过对前期24口卡钻井处理情况分析，明确了该地区卡钻类型主要分为掉块卡钻、沉砂卡钻两大类，并分析梳理了卡钻产生的原因及特点。本文从钻井液性能优化、井眼清洁监测系统应用、优化钻井工具、精细操作等方面制定了预防措施，为威远地区页岩气水平井旋转导向安全施工提供了借鉴作用。<br />
With the development of shale gas exploration and development, the horizontal well is the key technology for shale gas development. Due to the complex geological conditions of the shale gas reservoirs in Weiyuan County, Sichuan province, drilling sticking accidents often occur, the utili-zation rate of rotary steering is low in this area, which restricts the speed and efficiency of shale gas drilling. Based on the analysis of 24 sticking wells in the early stage, the types of sticking in this area are mainly divided into two types: block sticking and grit sticking, and the causes and characteristics of sticking are analyzed. In this paper, the preventive measures are formulated from the aspects of drilling fluid performance optimization, wellbore clean monitoring system ap-plication, drilling tool optimization and fine operation, etc., it provides a reference for the safe op-eration of rotary steering of shale gas horizontal wells in Weiyuan County.
