  • 摘要: 中国石化通过持续的攻关研究,形成了具有自主知识产权的页岩气工程配套技术,具备了页岩气水平井水平段长2 000 m、分段压裂20段以上的钻完井与压裂设计、施工能力,并实现了涪陵等地区页岩气资源勘探突破,促进了中国石化页岩气勘探开发进程。全面介绍了中国石化页岩气工程地质环境描述技术、优快钻井及井工厂技术、LVHS油基钻井液体系、SPF弹塑性水泥浆固井技术、分段压裂关键配套工具、滑溜水压裂液体系、页岩气水平井分段压裂技术和页岩气技术装备研发等技术及应用现状,并指出了未来页岩气工程技术的五大发展趋势。

     

    Abstract: Through years of research work,Sinopec formed its shale gas development supporting techniques with intellectual property rights and have the capability in drilling,completion and hydraulic fracturing design and application for staged horizontal well with lateral length 2 000 m and over 20 stages.Those techniques have been applied and some breakthroughs have been made in shale gas’exploration in areas such as Fuling.Those techniques application are helping to promote shale gas’exploration and development of Sinopec.This paper introduced the techniques in geological description,fast drilling and well plant,LVHS oil based drilling fluid,SPF elastic and plastic cementing slurry,staged hydraulic fracturing tool,slick water system,staged fracturing and instrumentations and pointed out the tendencies in shale gas exploration and development as engineering operation standardization and integration,secure and low cost drilling,more effective hydraulic fracturing,emphasis on environment protection and waterless fracturing.
