摘要： A packer tool comprises three or more slips (58) evenly distributed around a mandrel (1 1). Each slip comprises two members (66) with gripping teeth (63) which, except for one slip (58'), typically have the capacity to grip a well casing in opposite axial directions. The remaining slip has only one member with teeth able to grip the casing, the other slip member has dummy teeth (97) with nil gripping capacity. The latter teeth have blunt or rounded edges (98) and are not slanted in a selective gripping direction as the sharper teeth (64) of the other slip members.

摘要： A packer tool has safety devices to prevent premature and reverse setting and release operations. The safety devices are independent of shear-pin safety systems. Confined annular segments prevent a setting actuator piston from moving absent tool-setting hydraulic pressure. The setting pressure first moves a cylinder in an opposite direction to unroof the segments allowing them to exit confinement and free the piston to set the packing and the anchor slips. Release safety pins extend radially inward from a packing-holder collar into short slots formed on a mandrel surface, preventing the mandrel from being turned. Previous set motion causes the pins to leave the slots thereby freeing the mandrel to turn only after the tool has been set. A third safety device comprises an expanded ring which is dragged by the release cone during release motion until it lodges in a circumferential groove in the mandrel, locking against reverse movement.
摘要翻译：封隔器工具具有防止过早和反向设置和释放操作的安全装置。安全装置与剪切销安全系统无关。密封的环形部分防止设置致动器活塞移动，不存在工具设定液压。设定压力首先使气缸向相反方向移动，使气缸不会断开，从而使气缸能够排出限制，并释放活塞以设置填料并使锚固件滑动。释放安全销从填料保持器套环径向向内延伸到形成在心轴表面上的短槽中，防止心轴转动。先前的设定运动导致销离开槽，从而使心轴仅在工具被设置之后才转动。第三安全装置包括扩张环，其在释放运动期间被释放锥拖动，直到其卷入在心轴中的周向凹槽中，防止反向移动。

摘要： A technique enables anchoring of a tool in a wellbore. The technique provides traction against a well component without creating high stress concentrations that weaken the well component. An anchoring device comprises anchoring members that are selectively movable to an expanded configuration for anchoring the tool. The anchoring members have traction surfaces able to selectively engage a smooth anchoring surface of the well component at any desired location along the well component. Each traction surface is formed to facilitate traction while minimizing stress concentration.

摘要： A downhole tool (10) and a running tool (12) are described, each being retrievably settable within a suitably sized cased well bore without the need for any interaction between the downhole tool or the running tool and any restrictions or recesses in the well bore to land, anchor or retrieve either tool. The downhole tool has a mandrel (56), an anchoring means (74) mounted on the mandrel and controllably reconfigurable from a retracted configuration to permit movement of the downhole tool through the well bore to a radially expanded configuration for releasably engaging the cased well bore. The downhole tool anchoring means is reconfigured using a ratchet (61) that resists movement of the tool anchoring means from the expanded configuration back to the retracted configuration until a release mechanism is released to allow retraction of the downhole tool anchoring means and retrieval of the downhole tool from the well bore.
