以石油装备为载体,以综合能力训练为主线的装备类专业课教学模式改革与实践

Reform and Practice of Teaching Mode for Professional Courses of Equipment Majors Taking Petroleum Equipment as Carrier and Comprehensive Competence Training as Main Line

针对石油装备课程体系存在的教学体系固化、教学内容与能力培育脱节、学生课堂学习动力不足等突出问题,打破以石油装备知识体系为核心的传统课程体系和教学内容,提出“以油气装备为载体,以三基训练为目的”的教学思路。在教学实施过程中,以石油钻... More >>

川南X井区龙马溪组页岩气保存条件研究

Study on the Preservation Conditions of Shale Gas in the Longmaxi Formation of X Well Block, Southern Sichuan

川南X井区龙马溪组页岩气资源潜力巨大,明确其保存条件对勘探部署具有重要意义。本文基于构造特征、断裂体系、裂缝发育、埋深与地层压力等关键参数,系统评价了该区页岩气保存条件。结果表明:向斜区构造改造弱、封闭良好,为有利保存单元;背斜及... More >>
