摘　　要：浅层水平井具有埋藏浅,地层欠压实,胶结疏松的特点,为了满足热采的要求,油层套管要求尺寸较大,进而要求造斜段井眼较大,实现浅地层大尺寸井眼高造斜率非常困难,通过对造斜率理论的研究,在地层自身造斜率一定的前提下,通过研制专用导向工具能够提高浅层水平井造斜段的造斜率,达到井身设计要求,并在现场应用效果良好。Sallow horizontal well are charactered by shallow burial, worse compaction and unconsolidated. In order to meet the requirement of the thermal production, production casing and bore size in angle build-up interval can be required big size.so it is difficult to achieve high build-up rate in shallow layer and large hole. On the premise of fixing formation build-up rate, special directional tools are researched to enhance build-up rate in angle build-up interval, achieve requirement of well profile design, and applied successfully on the plot.
