Well Qing-92 is a sidetracked well with diameter of 139.7 mm in Zhongyuan Oilifeld. During the drilling process, dif-ifculties were encountered, such as large displacement, long openhole section, hard trajectory control, dififcult drilling lfuid property adjustment, dififcult completion logging and cementing operation, etc. Through optimizing large displacement sidetracking proifle, enhancing trajectory control, bit selection, promptly adjusting drilling lfuid property, and decently preparing completion logging and cementing operation, the well drilling favorable conditions are guaranteed. The successful drilling of the well plays a referencing role to similar type of well drilling in the future.
