Abstract: Well Qing-92 is a sidetracked well with diameter of 139.7 mm in Zhongyuan Oilfield. During the drilling process, difficulties were encountered, such as large displacement, long openhole section, hard trajectory control, difficult drilling fluid property adjustment, difficult completion logging and cementing operation, etc. Through optimizing large displacement sidetracking profile, enhancing trajectory control, bit selection, promptly adjusting drilling fluid 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.
