| Abstract: | The paper introduced ZJ02-PJ02 butted wells of Xinwen Mining Group,the designed depth of the shaft and the inclined well were 941.12m and 1203.00m,and these two wells was 252.00m 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,high-precision PST MWD and minimum curvature method were applied to calculate the drilling trajectory to guarantee the butting of two wells. |
