18、s fixed and one half is attached to the shaft.When the power section turns the drive shaft through the V-Pilot the swash plate oscillates moving the pump pistons(green)up&down.This is how the hydraulic power is generated to operate the tool.旋转挡板（黄色转盘和红色轴承），一半固定，一半与旋转轴承连接，当马达的转动通过传动轴总成和V-Pilot的旋转挡板时，

19、带动泵活塞上下运动(绿色)，这就是水力泵如何驱动V-Pilot.,Hydraulic Pump 水力泵,When the tool comes off vertical the activation leavers(above the pump)come in contact with the lower end of the pendulum and open a valve.The HP reservoir is directed to the pads at the bottom of the V-Pilot(looks similar to an AGS 4 pistons/pad)a

20、nd force is applied to the well bore to push the tool back to vertical.当产生井斜时，激活片（水力泵之上）推击打钟摆的低边并且开启其中的一个阀门，水力直接作用于V-Pilot的垫片，井壁的反作用力推动钻具回到垂直状态。,Hydraulic Pump 水力泵,Tool is meant to operate in sliding mode but will correct up to 5 RPM.工具采用滑动模式进行作业，5rpm校正 5 25 RPM pads will remain retracted and will d

21、rill or ream like a straight motor.5-25rpm时，垫片处于收位状态，如同一条直马达Above 25 30 RPM centrifugal forces will pull the pendulum to one side inside the housing.One or two activation leavers will then be activated by the pendulum being off center and the hydraulics will extend one or two sets of pad pistons.25-

22、30rpm，钻具离心力将产生偏向一边的大钟摆力，V-Pilot的一个或两个垫片在大钟摆力的作用下偏离中心，液压将推动另外的一或两个活塞,V-Pilot 9600 String Rotation 钻具的旋转,Above 75 RPM was specifically for the Gen II,single pads and a lot of mass,they would extend at these speeds without hydraulic assistance on centrifugal force alone.The Gen III has less effect for

23、the pistons to extend on centrifugal force only as the mass of the individual pistons are much lower.V-Pilot 第二代的转速可高于75rpm，大质量单个垫片可以高速离心延伸，无需水力协助。V-Pilot 第三代的活塞质量更小，其高速离心力较小。The tool only functions in sliding mode If you rotary drill the tool becomes an 11”motorized drill collar.It will drill but w

24、ill not auto correct for inclination.one or two pads will extend.V-Pilot 只在滑动模式下产生作用，如果旋转V-Pilot就成为一个11”的电子钻铤，可以继续钻进但不能自动校正井斜。旋转时一到两个垫片会延伸出来。,V-Pilot 9600 String Rotation 钻具的旋转,What does it do?如何工作？,Initiates vertical correction at 0.2 degrees inclination 当井斜大于0.2时自动校直Bit driven by GeoForce constant
