摘要： A latching system for maintaining the position of a component within a downhole drill string section during operation of a drill string. One preferred latching system embodiment has a shoe member including a cavity for receiving a component, a chamber opening into the shoe member cavity, an engagement member movable in the chamber between a retracted position and an engagement position, a first passage in fluid communication with the chamber and extending to an end surface of the shoe member, and a second passage extending from an outer side surface of the shoe member to the first passage. A pressure differential between pressure in the first passage and pressure in the second passage alters the position of the engagement member.

摘要： A system for damping vibration in a drill string can include a valve assembly having a supply of a fluid, a first member, and a second member capable of moving in relation to first member in response to vibration of the drill bit. The first and second members define a first and a second chamber for holding the fluid. Fluid can flow between the first and second chambers in response to the movement of the second member in relation to the first member. The valve assembly can also include a coil or a valve for varying a resistance of the fluid to flow between the first and second chambers.

摘要： An apparatus for measuring the bending on a drill bit operating down hole in a well may comprise at least three pockets circumferentially spaced equidistantly around the drill collar of the drill string to which the drill bit is attached. Four strain gauges are equidistantly circumferentially spaced around each of the pockets so as to form first and second sets of strain gauges. The strain gauges in the first set are connected into one Wheatstone bridge while the gauges in the second set are connected in a second bridge. Each of the strain gauges that are oriented similarly within each of the pockets are connected in series within a single leg of a bridge so that the output voltage of the bridge is unaffected by bending in the drill string. The output of first bridge is used to determine the bending on the drill bit. Further, an apparatus for measuring the bending, weight, and torque on a drill bit operating down hole in a well may comprise at least three pockets circumferentially spaced equidistantly around the drill collar of the drill string to which the drill bit is attached with twelve strain gauges that are equidistantly circumferentially spaced around each of the pockets so as to form first and second sets of strain gauges. The arrangement of the twelve strain gauges allow for a bending on bit measurement that cancels out the affects of the weight on bit and torque on bit.
摘要翻译： 用于测量在井中钻孔的钻头上的弯曲的装置可以包括围绕钻头钻头附接的钻柱的钻铤周向间隔开的至少三个凹坑。 四个应变计围绕每个凹穴等距地周向间隔开，以便形成第一组和第二组应变计。 第一组中的应变计连接到一个惠斯通电桥中，而第二组中的测量仪连接在第二桥中。 在每个凹穴内相似地定向的每个应变计在桥的单个支腿内串联连接，使得桥的输出电压不受钻柱中的弯曲的影响。 第一桥的输出用于确定钻头上的弯曲。 此外，用于测量井中钻头钻孔的弯曲，重量和扭矩的装置可以包括至少三个围绕钻柱的钻铤圆周间隔地间隔开的钻孔，其中钻头附接有十二个应变 围绕每个凹穴等距地周向间隔开的量规，以便形成第一组和第二组应变计。 十二个应变计的布置允许在位测量上进行弯曲，从而消除位上的重量和位上的扭矩的影响。
