| 摘 要： | 利用水平液面与钻孔垂直面的相对倾角来计算钻孔顶角的方法，是一种新的孔内电视系统测量孔斜的方法。文中对该方法测量原理从理论上进行了分析论证。该方法与JCD—2型测定方法比较，解决了浑水中不能测量，光视角产生的失真和光的折射率产生的偏差等问题。

| Abstract: | This paper introduces the method of calculating the vertex angle of borehole, which is the relative dip an gle formed by the horizontal liquid level and the vertical plane of the borehole, it is a new inethod to measure the in clination of borehole by down - hole TV system. The measuring principle of the method is theoretically verified.Comparing this method with the measuring method from Model JCD - 2 instrument, the problems of the impossibil ity of measuring in turbid water and the distortion from optic visual angle, the deviation from the refractivity of light etc. can be solved. |
