摘要： A portable apparatus for refacing either pin or box portions of damaged pipe sections on site including a housing, a set of truing up plates mounted on the housing for initially positioning the damaged pipe sections inside the apparatus, a set of jaws mounted on the housing and provided with movable elements for adjustably securing the surface of the pipe section, a ring gear rotatably mounted on the housing, and resurfacing tools provided on the rotatable ring gear. An associated gearing mechanism tracks the resurfacing tool toward and away from the center of the pipe section as the ring gear is rotated by an attached conventional power source.Alternative gauging arms are provided for initially positioning the damaged pipe section inside the apparatus.

摘要： A directional drilling apparatus includes a two part tubular body including an upper section and a lower section adapted to rotate with respect to one another, the upper section including threads for attaching the apparatus to a drill string, the upper section including at its lower end portion a slot including a straight portion which is generally aligned with the axis of the upper section and an offset portion which is spaced laterally from an spaced radially from the vertical section, connecting teeth for forming a connection which rigidly affixes each of the upper and lower section with respect to each other so that they are prevented from rotating with respect to one another, and a sleeve carried by the lower section and slidably movable with respect to the upper section, the sleeve including a locking pin which extends into the slot, the pin being adapted to move longitudinally and laterally within at least a portion of the slot and into either the vertical or laterally offset a section thereof.

摘要： A variable angle directional drilling "sub" provides a shifting end portion which allows the sub to be rotated from a first, in-line, axially straight orientation with the drill string to a selected second, angled or "bent" position, which second position is normally assoicated with conventional bent "subs" which are permanently structured in the bent position. The tool provides a multiple choice of varying angles to the sub in its bent position to satisfy differing directional drilling situations. A first embodiment (FIGS. 1-7) is manually set and varied at the surface by positioning two angularly marked sections temporarily rotatable with respect to each other until the desired angle set is matched up, while a second embodiment (FIGS. 8-9) is motor driven to allow varying the angle direction while "down in the hole". The device rotatably shifts about an off-set axis of rotation from the first (in-line) position to the second (bent) position either (in the first manually adjustable embodiment) upon the application of torsional force thereto, which torsional force can be applied, for example, by the actuation of a "turbodrill" (normally attached in operation), or (in the second motorized embodiment) by an electrical signal from the surface to a built-in motor contained within the tool. The axially aligned first position allows easy entry of the drill string, sub, and turbodrill into the well hole, while the second bent position is used down in the hole to commence directional dirlling at the desired off-set or deviated angle. In the first embodiment, the sub will return gradually to its original axially aligned position when the device is withdrawn from the wellhole, as such position is the path of minimum resistance for the withdrawing drill string and torsion is not present to hold the sub in the bent position; while in the second embodiment the built-in motor is merely backed off to its original position.

摘要： A directional drilling "sub" provides a shifting end portion which allows the sub to be rotated from a first in-line axially straight orientation with the drill string to a second angled or "bent" position which second position is normally associated with conventional bent "subs" which are permanently structured in the bent position. The device shifts from the first (in-line) position to the second (bent) position upon the application of torsional force thereto which torsional force can be applied, for example, by the actuation of a "turbodrill" (normally attached thereto in operation). The device can be manufactured or machined to provide varying angles to the sub in its bent position to satisfy differing directional drilling situations. The axially aligned first position allows easy entry of the drill string, sub, and turbodrill into the well hole, while the second bend position is used to commence directional drilling. The sub will return gradually to its original axially aligned position when the device is withdrawn from the wellhole, as such position is the path of minimum resistance for the withdrawing drill string and torsion is not present to hold the sub in the bent position.

摘要翻译： 定向钻孔“子”提供了一个移动端部，其允许副从与钻柱的第一直列轴向直线方向旋转到第二倾斜或“弯曲”位置，该第二位置通常与常规弯曲“ 子“，其永久地构造在弯曲位置。 当施加扭转力时，例如通过致动“涡轮弹簧”（通常在操作中附接到其上），可以施加扭转力，装置从第一（直列）位置移动到第二（弯曲）位置 ）。 该装置可以被制造或加工以在其弯曲位置处向副部提供变化的角度，以满足不同的定向钻井情况。 轴向对准的第一位置允许钻柱，副和涡轮容易地进入井孔，而第二弯曲位置用于开始定向钻井。 当装置从井眼中取出时，副翼将逐渐返回到其原始的轴向对准位置，因为这样的位置是抽出钻柱的最小阻力的路径，并且不存在扭转以将副夹持在弯曲位置。
