摘要： A lock assembly for a mechanically set packer for deep deployments is described. The lock housing wall has at least one bore for a rod piston that is selectively actuated when wellbore hydrostatic is allowed to reach on side of the piston. Movement of the piston, after breaking a shear pin, allows a c-ring to spring outwardly and out of a locking groove in the mandrel so that the mandrel can be string manipulated with respect to the housing to set the packer. Once unlocked the lock assembly remains defeated. The piston can be optionally exposed to hydrostatic and will unlock at a given depth without manipulation of the wellbore annulus pressure. Other mechanisms to admit wellbore hydrostatic to move the piston or to move the piston in general by other techniques are described.

摘要： A hydraulically actuated setting tool has a plurality of pistons that move in tandem when unlocked. The pistons are initially in pressure balance to take a load off a single locking mechanism that retains all the pistons. The pistons move due to admission of hydrostatic and/or applied pressure from the annulus on one side of each piston with an opposite side exposed to atmospheric pressure. The locking member is exposed to the annulus and is located away from any atmospheric chambers associated with the pistons. In this manner the components can be made thicker to resist burst and collapse pressure and the loads on the locking member reduced due to initial piston pressure balance configuration. Depths of greater than 10,000 meters can be used due to one or more of the described design features.
摘要翻译：液压致动的固定工具具有多个在解锁时串联移动的活塞。活塞最初处于压力平衡状态，从而保持所有活塞的单个锁定机构的负载。活塞由于静压和/或施加的压力从每个活塞的一侧上的环形空间移动，相对侧暴露于大气压力。锁定构件暴露于环形空间并且位于远离与活塞相关联的任何大气室。以这种方式，可以使部件更厚以抵抗爆裂和压缩压力，并且锁定构件上的负载由于初始活塞压力平衡配置而减小。由于一个或多个所描述的设计特征，可以使用大于10,000米的深度。

摘要： The removable plug features a solid material that is housed in a porous container that has its shape changed to transition from the run in shape to the set shape. A running string and setting tool that creates relative movement deliver the plug and pull on its lower end while holding the top stationary against a backing plate. The container is pulled into itself as the radial dimension grows for the set. There can be a mandrel that remains in position and can lock to the backing plate or alternatively there can be no mandrel or a removable mandrel. The porous container can be removed in a variety of ways to let the solid material escape to be removed with fluid circulating in the wellbore. Alternatively the mandrel can be undermined to let the solid material escape for recovery.

摘要： Wedge shaped elements form a ring structure that can increase in diameter for a grip using relative axial motion of adjacent segments. The adjacent seal is further separated from access to the edges of the adjacent segments that move relatively by ring segments attached to the wide dimension of the segments that face the seal. The ring segments move out with the wedge elements to which they are attached so that in the set position of the seal there is an enhanced barrier against the surrounding tubular with the ring segments. The ring segments further block access of the seal under compressive loading to the interface locations between the wedge shaped elements so that their relative axial movement does not trap a portion of the seal and initiate cracks in the seal that can lead to leakage past the seal.
摘要翻译：楔形元件形成环形结构，其可以使用相邻片段的相对轴向运动来增加手柄的直径。相邻的密封件进一步与相邻节段的边缘分离，相邻的段的边缘相对移动地连接到面向密封件的段的宽尺寸上的环段。环形段与其所附接的楔形元件一起移出，使得在密封件的设定位置中，环圈的周围管状物具有增强的屏障。环形段进一步阻止密封件在压缩载荷下的进入到楔形元件之间的界面位置，使得它们的相对轴向移动不会捕获密封件的一部分并且引发密封件中的裂纹，这可能导致泄漏通过密封件。

摘要： A vegetation trimmer with a spool and hub assembly has a cutting filament wound around the spool. The free end of the filament extends through an aperture in the hub into the cutting plane. The spool and hub are rotated at a high rate to allow the filament to cut vegetation. The spool includes a plurality of arms which engage with arms on the hub. When the spool is acted upon, the arms on the spool disengage with the arms on the hub to permit relative rotation of the spool to the hub to feed additional filament into the cutting plane. An indexing feature is used to regulate the amount of additional cutting filament that is allowed to be fed into the cutting plane. When the spool and hub are engaged, the cutting filament is forcible clamped between the arms on the spool and the arms on the hub to prevent the centrifugal force generated by the filament in the cutting plane from acting upon the filament wound around the spool at cutting speed so that the filament does not have means to tangle or weld together and break prematurely. Upon disengagement of the spool and hub, the cutting filament is released to permit the additional cutting filament to be fed into the cutting plane.

摘要： A downhole well tool having a component with a metal surface to which a sealing material is adhered is disclosed. The sealing material is bonded to the metal surface through the use of an energetic material disposed between the sealing material and the metal surface. Upon activation or initiation of the energetic material, the sealing material becomes bonded to the metal surface. A plastic layer may be disposed between the sealing material and the metal surface to facilitate bonding sealing material to the metal surface. The energetic material is used to bond the plastic layer to the metal surface and may be used to bond the plastic layer to the sealing material.

摘要： An expandable packer or anchor is disclosed. It features a gripping device integral to or mounted in a sleeve over the mandrel. Upon expansion, a sealing element engages an outer tubular and the gripping device, such as wickers on slips, preferably digs into the outer tubular. The expansion is preferably by pressure and can incorporate pressure intensifiers delivered by slick line or wire line. Release is accomplished by a release tool, which is delivered on slick line or wire line. It stretches the anchor or packer longitudinally, getting it to retract radially, for release. The release tool can be combined with packers or anchors that have a thin walled feature in the mandrel, to release by pulling the mandrel apart.
