Abstract
The paper introduced Chaoyanggou oilfield about the well structure characteristics,formation lithology and difficulties in horizontal well trajectory control.Based on these characteristics and deflection rates in different stratums,effective trajectory control scheme was designed;reasonable deflecting tool and drilling tool assembly were selected with reasonable drilling parameters and technology for shallow horizontal well construction.
