▪ When one (or two) valve is opened by the pendulum, it allows the hydraulic fluid to actuate one (or two) of the 4 pistons in the opposite side. ▪ 当一个或两个阀门被大钟摆打开之后，水力流体激活反方 向的4个活塞中一个或两个 ▪The pistons maintain pressure against the hole wall forcing the bit (push-the-bit) to drill laterally bringing the well back to vertical. The pistons will stay extended until the well returns to the vertical and the valve(s) are no longer activated and are retracted by springs. ▪ 活塞推击井壁，使钻具回到垂直状态。活塞的位置一直延 伸直到井眼垂直没有侧向力为止
How it Works 工作原理
▪ The GeoForce motor is powered by the drilling fluid and it’s
shaft rotation is transferred to the shaft in the lower section.
▪ GeoForce马达通过泥浆驱动将动力传递到下部的垂直钻 井设备部分 ▪ The shaft rotation powers up the hydraulic pumps. ▪ 马达传动轴驱动垂直钻井设备的液压泵
