摘要： A fill up tool has an adjustable length to selectively lengthen the fill up a tool or retract to be positioned completely above the elevator so that elevator movement will not interfere with the fill up tool. The seal is fixed to the tool so that the load caused by the pressurized seal does not have to be balanced by the operating force of the piston. A full open valve is operated when the tool is extended to fill up or take flow back.

摘要： A fill up and circulating tool has a threaded hub covered by a rapidly removable cover. The cover protects the threads from damage until a well kick occurs. When the well kicks the cover is rapidly removed and the fill up tool is brought down with the top drive to which it is connected. The top drive rotates the mandrel of the tool to make the threads up to a coupling on the uppermost stand of casing to provide a metal to metal seal that can resist a well kick coming up through the casing and around the outside of the fill up tool. The top drive system has a surface valve that can be closed quickly to contain the kick through the fill up tool.

摘要： Spring loaded dogs are attached to the housing to engage the casing internally or externally to facilitate extension or retraction of the slips that selectively grab the topmost of a string of casing. When the tool is suspended from the top drive, its components are rotationally locked to facilitate insertion into the casing stand on top of a string being run in the hole. Some set down weight allows top drive rotation to move a multi-ramped mandrel axially because that mandrel is rotationally locked to the housing that is held fast by the spring loaded dogs bearing on the casing. Once the slips are extended with a specified torque applied from the top drive, further setting down weight locks the components and the housing so that applied rotation with setting down weight will turn the casing string but will not torque up the slips beyond their set position.

摘要： A rotary table has a non-circular drive recess in the central opening which carries an assembly of mounting structures and slip carriers that when joined together fit in the non-circular drive recess. The plurality of slip carriers are distributed about the periphery of the drive recess are extended down into the central opening of the rotary table. A slip and die arrangement is situated on each slip carrier. Slip manipulation drive cylinders, are distributed about the assembly periphery and move a synchronizer plate that moves the slips vertically to grip or release pipe extending through the opening of the rotary table.

摘要： A casing running tool is connected to a top drive with a clutch that operates with set down weight against a spring resistive force. Setting down weight with rotation in a first direction raises an actuation member that pushes the slips out radially. The weight of the string then keeps the slips in position so that the string can be picked up and the rig floor slips removed followed by lowering the string while circulating and rotating. With slips set inside the joint and the string hanging free, rotating the top drive rotates the string as the string is lowered. With slips again supporting the string on the rig floor the top drive can be rotated in an opposed direction with weight set down to back off the slips and to remove it from the top joint.
摘要翻译： 套管运行工具通过离合器连接到顶部驱动器，该离合器抵抗弹簧阻力而以降低的重量运行。 通过沿第一方向旋转来设定重量提高了使滑动件向外径向推动的致动构件。 弦的重量然后将滑块保持在适当的位置，以便可以拾取绳索，并且钻机底盘被移除，随后在循环和旋转时降低弦线。 使用滑块设置在接头内部并且弦线悬空，旋转顶部驱动器会随着琴弦的降低而旋转弦线。 随着再次支撑在钻机地板上的绳索，顶部驱动器可以在相反的方向上旋转，重量被设置成背离滑动件并将其从顶部接头移除。

摘要翻译： 弹簧加载的狗被附接到壳体以在内部或外部接合壳体，以便于选择性地抓住套管的最顶端的滑块的伸出或缩回。 当工具从顶部驱动器悬挂时，其组件被旋转地锁定，以便于将插入到在孔中运行的串的顶部上的壳体架中。 一些下压重量允许顶部驱动器旋转以轴向移动多倾斜心轴，因为该心轴被旋转地锁定到壳体上，该壳体由在轴承座上的弹簧加载的滑块保持。 一旦滑块以从顶部驱动器施加的指定扭矩延伸，则进一步调节重量将锁定部件和壳体，使得施加的旋转与降低重量将转动套管柱，但是不会将滑块扭转超过其设定位置。
