The well Nanpu12-X168 is the first extended reach well in No.2 island of Jidong oilfield, with the total depth 5,040 m, the maximum deviation 72.4°, the horizontal displacement 3,802.33 m, the ratio of horizontal to vertical 1.49 and length of basaltic formation 1,068 m. In this well, the BH-KSM drilling fluid system is applied in the third and fourth interval, and this system has good performance of sealing cooperated with polyamine and BZ-DFT, which it can balance the formation pressure with the density of 1.25 g/cm3. In field operation, keeping the contents of KC1 and BZ-BBJ at 5%-7% and 0.2%-0.3%, adding polyamine white asphalt and polyalcohol on time, and the application in Jidong oilfield is successful.
