Sinopec Engineering Technical Advance and Its Developing Tendency in Shale Gas

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.
