The paper introduced ZJ02-PJ02 butted wells of Xinwen Mining Group, the designed depth of the shaft and the inclined well were 94112m and 120300m, and these two wells was 25200m apart. The designed well structure was trisected with drilling and angle building equipment rationally installed. Tower-type pendulum drilling-assembly was used to prevent well deviation. Drilling pressure, drilling ratio, pumping volume and drilling fluid were selected according to the different situation in different well section, highprecision PST MWD and minimum curvature method were applied to calculate the drilling trajectory to guarantee the butting of two wells.
