Drilling and downhole complex treatment of Well Xiangtaodi-1 for shale gas geological survey in Yuanma Basin
-
摘要: 为评价雪峰古陆周缘页岩含气性,2019年在沅麻盆地施工了页岩气地质调查井湘桃地1井,完钻井深1850.88 m,全井取心,平均岩心采取率97.24%。施工中应用XY-8型钻机,采用三开井身结构,配合录井及测井技术,并优选钻具组合、钻头、钻进参数、钻井液性能。因牛蹄塘组碳质泥岩失稳掉块及钻探工艺调整不及时发生了卡钻、埋钻、钻具折断等井下复杂,采取螺杆马达侧钻绕障予以解决,侧钻后同径继续钻进806.87 m至完钻。该井的顺利完钻和井下复杂处理方法为同类地区地质调查井施工提供了可借鉴的经验。Abstract: In order to evaluate the gas bearing property of shale around Xuefeng Ancient Land, Well Xiangtaodi-1, a shale gas geological survey well, was constructed in Yuanma Basin in 2019. The completed drilling depth was 1850.88m. the whole well was cored, and the average core recovery rate was 97.24%. XY-8 drilling rig is used in the construction, which adopts third spud hole structure, cooperate with gas logging and comprehensive geophysical logging technology, and optimizes the BHA, bit, drilling parameters and drilling fluid performance. Due to the instability and block falling of the carbonaceous mudstone in Niutitang Formation and the untimely adjustment of the drilling process, the downhole complications such as drill rod sticking, drill rod burying and drill tool breaking occurred. The screw motor sidetracking is adopted to bypass the obstacles, so as to solve the downhole problems such as sticking and burying. After sidetracking, continue to drill 806.87m with the same diameter until the completion of drilling. The successful completion of the well and the complex downhole treatment methods provide reference experience for the construction of geological survey wells in similar areas.
