| 中文摘要:页岩气是指开采自富烃页岩层的非常规天然气资源，资源储量的调查评价主要依托钻探技术。页岩具有较强的水敏性，在页岩气勘察钻进施工中，井内易发生坍塌、剥落造成超径或缩径等井壁失稳现象。盐津1-2井完井井深1554.06 m，是目前云南省页岩气资源勘察施工中最深的一口井。针对页岩气井钻井技术要求，从钻井设备、井身结构、钻进参数、钻具组合、钻井液、井斜控制、事故预防等方面进行选择、设计、优化，成功地完成了盐津1-2井的钻井施工。总结了该井施工中的经验和存在的问题，可为以后同类工程施工提供参考。 |

| Abstract:Shale gas is an unconventional gas resource produced from hydrocarbon rich shale, the investigation and evaluation of resource reserves mainly rely on drilling technology. Shale has strong water sensitivity, collapse and spalling often happen, which cause wall instability of diameter shrinkage and oversize in shale gas exploration drilling construction. Based on the technical requirements of shale gas drilling, the selection, design and optimization are made in drilling equipments, wellbore structure, drilling parameters, drilling tool assembly, drilling fluid, deviation control and accident prevention. Yanjin well 1-2 is successfully completed with the final depth of 1554.06m and becomes the deepest well in Yunnan shale gas resource investigation construction. This paper summed up the experience and existing problems in the well construction. |
