| 中文摘要:为了研究油页岩的地下原位开采技术，设计施工了FK-1井。该井地处吉林省松原市扶余县，完钻井深500 m，完钻层为嫩江组地层。该井设计施工中主要需克服大口径钻井的保直钻进、软塑性地层的裸眼钻进、水敏性地层中钻井液的应用、泥页岩层中发生钻头泥包现象及原位开采井的特殊成井、固井等问题。通过对钻井设备的优选，钻井液性能和井身结构的相应优化，钻头和钻具组合的选择等措施来解决钻井过程中的施工难题。设计结果在施工过程中进行了应用，施工效果良好，缩短了钻井时间，减少了钻井投入，解决了施工难题，为同类钻井的施工提供了借鉴和指导依据。 |

| Abstract:In order to study the underground oil shale in situ mining technology, FK-1 well is designed and constructed in Fuyu County of Jilin Province with completed depth of 500m, the completion layer is Nenjiang formation. The straight keeping of large diameter drilling, open hole drilling in soft plastic formation, drilling fluid application in water sensitive formation and bit balling in mud shale formation, as well as special well completion and cementation of in situ production well are considered and overcome in the design and construction. The construction difficulties in drilling process are solved by the optimization of drilling equipments and drilling fluid performance, the corresponding optimization of well structure and the choice of drill bits and BHA. Good construction effects are received with shortened drilling time and reduced drilling investment. |
