    • A system and method for surface steerable drilling are provided. In one example, the method includes monitoring operating parameters for drilling rig equipment and bottom hole assembly (BHA) equipment for a BHA, where the operating parameters control the drilling rig equipment and BHA equipment. The method includes receiving current inputs corresponding to performance data of the drilling rig equipment and BHA equipment during a drilling operation and determining that an amount of change between the current inputs and corresponding previously received inputs exceeds a defined threshold. The method further includes determining whether a modification to the operating parameters has occurred that would result in the amount of change exceeding the defined threshold and identifying that a problem exists in at least one of the drilling rig equipment and BHA equipment if no modification has occurred to the operating parameters. The method includes performing a defined action if a problem exists.
    • 提供了一种用于表面可操纵钻孔的系统和方法。 在一个示例中,该方法包括监测用于BHA的钻机设备和井底组件(BHA)设备的操作参数,其中操作参数控制钻机设备和BHA设备。 该方法包括在钻井操作期间接收与钻机设备和BHA设备的性能数据相对应的当前输入,并确定当前输入和对应的先前接收到的输入之间的变化量超过限定的阈值。 该方法还包括确定是否已经发生对操作参数的修改,其将导致超过定义的阈值的变化量,并且如果没有修改已经发现钻井设备和BHA设备中的至少一个存在问题,则 操作参数。 该方法包括在存在问题的情况下执行定义的动作。

    • An adjustable socket wrench with bolt head locking arm for engaging, removing and replacing different size bolts in a work piece. The socket wrench is designed to engage a bolt head at right angles and when locked on the bolt head holding the head with zero tolerance for ease in loosening and tightening the bolt. The wrench includes a wrench body with an upper end portion, a middle portion and a lower end portion. A channel is cut across the width of the upper end portion of the wrench body for receiving a first sliding jaw and a second sliding jaw. The bolt head is received between the first and second jaws. A first jaw guide arm is pivotally mounted on the wrench body with one end of the first jaw guide arm engaging the first jaw. A second jaw guide arm is pivotally mounted on the wrench body with one end of the second jaw guide arm engaging the second jaw. The first jaw guide arm is pivotally mounted to the bolt head locking arm. The bolt head locking arm in turn is pivotally mounted to a first pivot arm. The second jaw guide arm is pivotally mounted to a second pivot arm. The first and second pivot arms are engaged by a tightening nut threaded on the lower end portion of the wrench body. When the tightening nut is threaded upwardly on the wrench body, the first and second pivot arms move upwardly pivoting the first and second jaw guide arms inwardly. The first and second jaw guide arms move the first and second jaws toward each other for engaging a bolt head received therebetween.
    • 带螺栓头锁定臂的可调套筒扳手,用于接合,拆卸和更换工件中不同尺寸的螺栓。 套筒扳手设计成以直角接合螺栓头,当锁定在螺栓头上时,头部保持零位,以方便松动和拧紧螺栓。 扳手包括具有上端部分,中间部分和下端部分的扳手主体。 在扳手主体的上端部的宽度上切割通道,用于接收第一滑动卡爪和第二滑动卡爪。 螺栓头被容纳在第一和第二夹爪之间。 第一钳口引导臂可枢转地安装在扳手主体上,第一钳爪引导臂的一端与第一钳口接合。 第二钳口引导臂枢转地安装在扳手主体上,第二钳爪引导臂的一端接合第二钳口。 第一钳口引导臂枢转地安装到螺栓头锁定臂。 螺栓头锁定臂依次枢转地安装到第一枢转臂。 第二钳口引导臂枢转地安装到第二枢转臂。 第一枢转臂和第二枢转臂通过拧在扳手主体的下端部上的紧固螺母接合。 当紧固螺母在扳手主体上向上螺纹时,第一和第二枢转臂向上移动,使第一和第二夹爪引导臂向内枢转。 第一和第二钳口引导臂将第一和第二钳口彼此移动以接合容纳在它们之间的螺栓头。
