采用XYB244/273—1型可变角度造斜器,可在地面通过钻杆向井内投入钢球,以改变钻具弯曲角度和弯曲方位,从而达到井眼设计要求。笔者在详述了结构原理和试验情况后指出,这种造斜器与造斜钻头、随钻测斜仪配套,可实现造斜和扭方位一次成功,每次造斜可减少起下钻2～3次,节省2～3天时间。 The use of XYB244 / 273-1 variable angle whipstock can be put on the ground through the drill pipe into the well to change the drilling tool bending angle and bending direction, so as to achieve the wellbore design requirements. After detailed description of the principle of the structure and the experimental conditions, the author pointed out that such a whipstock and a bevelled drill are matched with a drilling inclinometer to achieve a successful slash and twist position. ~ 3 times, save 2 ~ 3 days time.
