| 中文摘要:为最大限度地降低页岩气钻井对环境的影响，涪陵页岩气田通过钻井技术方案优化和现场实践探索，形成了涪陵页岩气“绿色”钻井关键技术。本文从页岩气水平井钻井工艺特点和涪陵地区自然环境特征入手，分析了涪陵地区页岩气钻井对环境的挑战，在此基础上构建了以油基钻井液回收利用、油基钻屑无害化处理、油改电、钻井设计与施工工艺优化以及“井工厂”钻井为核心的“绿色”钻井技术体系。该技术在涪陵页岩气田一期产建中推广应用，减少二氧化碳排放20.9万t，井场占地面积同比减少30%，做到了零污染、零排放。涪陵页岩气田“绿色”钻井技术的应用极大地降低了钻井作业对环境的影响，同时为国内页岩气钻井发挥了重要的示范和指导作用。 |

| Abstract:To minimize the impact of shale gas drilling on environment to the lowest level, the key technologies for drilling is formed in Fuling shale gas field by technology program optimization and field practice exploration. This paper analyzes the impact of shale gas drilling on the environment in Fuling area starting with horizontal drilling characteristics and environmental features there. On this basis, “green” drilling technical system is constructed with core of oil-based drilling fluid recycling, harmless treatment of oil-based cuttings, converting oil to electricity, drilling design and construction technology optimization as well as “well factory” pattern drilling. This technology was popularized and applied in the first phase production of Fuling shale gas field, carban dioxide emission is reduced 209 thousand tons, well site area is reduced 30% with zero pollution and zerp emission. |
