Well Jin27-P1 is a horizontal well drilled in Liaohe Oilfield, and it set the records of shortest drilling cycle and lowest cost in Liaohe, since the carrying out of the program of horizontal drilling and production matching technology research began from the 'Eighth Five Year Plan'. In drilling of this hole, two sets of MWD systems with Gamma module were firstly used for more precise trajectory control, while two sets of BHAs and drilling fluid systems were specially used for the building up section and the horizontal section. The well was successfully drilled without any troubles, with a drilling cycle of only 25 days, a measured depth of 1559.62m and a vertical depth of 1205.47m; the horizontal interval was 200.13m, and the maximum hole inclination was 95.5°. The drilling process and techniques taken are described in detail in this paper.
