摘要： The invention comprises a uniquely shaped sealing element or elements for a packer. In an application using a stack of elements, the upper element is configured so that at least a portion of its inside diameter represents an interference fit with the mandrel onto which it is mounted. A built-in moment within the packing element occurs as a result of the partial interference fit. Additionally, a taper is provided which, in effect, shifts the point of contact of the upper element closer to a central element, tending to better give extrusion support to the central element. The taper also facilitates the creation of a resistive moment which fights the tendency of the upper element to extrude in the upper outermost corner of the upper element, for example. The central element can also be installed on a mandrel with interference throughout its length to create a built-in radial force urging the element back into its original shape after it is expanded and allowed to relax. Using such shapes, the need to mechanically stretch the elements longitudinally, after they are relaxed so that the packer can be withdrawn without interference in a close running situation, is eliminated.

摘要： A control apparatus preferably for concurrently protecting a downhole fluid pressure operated device from excessive fluid pressures and indicating at the surface when any such excessive fluid pressure level has been reached. The pressured fluid is directed through a bore of a sleeve, and a flow plug is normally located in an axially remote position relative to the sleeve bore. The flow plug is moved upon the occurrence of a predetermined fluid pressure across the downhole device to move into the bore of the sleeve and produce a flow constriction which will result in an detectable fluid pressure signal at the surface. Concurrently, a bypass flow path is established around the fluid pressure operated device to immediately reduce the fluid pressure being applied to such device.

摘要： An apparatus for orienting a downhole tool relative to a borehole. The invention comprises a phase change material such as a shape memory metal engaged with the tool in an initial position which is activatable to move into an operating position relative to the tool. An actuator activates the phase change material to orient the tool relative to the borehole. The member is engaged with said housing and with the phase change material for selective movement relative to said housing between an initial position and an operating position. The actuator activates said phase change material to move said member. A return spring can move the phase change material to or from the initial position. The invention can be combined with a logging tool or other downhole device to orient the tool within a borehole. In different applications, the invention can center the tool or urge the tool against one side of the borehole wall.

摘要： An apparatus and method for producing through a casing without perforation are disclosed. The casing can be rotated while it is cemented and includes a multiplicity of sliding sleeve valves. Each of the valves selectively covers a plurality of pistons, each of which preferably has a rupture disc mounted therein. A pressure-regulating device is provided in association with each rupture disc to ensure retention of sufficient internal pressure in the tubing such that all discs eventually burst without any short circuiting through the discs which ruptured earlier. The outward movement of the pistons acts to assist in fracturing the formation. Thereafter, the pressure used to rupture the discs aids in further channeling the fluid energy of the fluid rupturing the discs, as well as putting additional pressure on the movable pistons to further stress fracture the formation.As the piston is pumped outward, the grease that is held captive within the piston assembly is forced outward through a bladder. As the grease is pumped out, it displaces the cement slurry and flushes the face of the formation directly in front of the piston. Serrations on the end of the piston assembly concentrate the stresses, causing the piston assembly to bite into the formation. As the piston continues to penetrate the formation, the grease is ejected through the serrations, which helps to further flush the face of the formation. The ejected grease also tends to act as an inhibitor which prevents the cement from setting up in the area around the piston. The interior of the piston assembly will still contain grease which helps prevent the temporary restriction from dissolving.
摘要翻译：公开了一种通过无穿孔的套管生产的装置和方法。外壳可以在胶合时旋转并且包括多个滑动套筒阀。每个阀选择性地覆盖多个活塞，每个活塞优选地具有安装在其中的破裂盘。与每个破裂盘相关联地设置压力调节装置，以确保在管道中保持足够的内部压力，使得所有的盘片最终爆裂，而不会通过先前破裂的盘片发生任何短路。活塞的向外运动有助于压裂地层。此后，用于破坏盘的压力有助于进一步引导破裂盘的流体的流体能量，以及在可移动活塞上施加额外的压力以进一步压力破坏地层。当活塞被向外泵送时，保持在活塞组件内的润滑脂被迫向外通过气囊。当油脂被抽出时，它移动水泥浆并直接在活塞前冲刷地层的表面。活塞组件端部的锯齿集中应力，使活塞组件咬入地层。当活塞继续穿透地层时，润滑脂通过锯齿喷射，这有助于进一步冲刷地层的表面。排出的油脂也倾向于作为阻止水泥在活塞周围的区域内形成的抑制剂。活塞组件的内部仍然含有润滑脂，有助于防止临时限制溶解。

摘要： An electroplating shield for providing controlled electroplating of an article having an irregular surface of crests and valleys. The shield, being made of a nonconductive material such as chlorinated polyvinylchloride, includes at least one aperture that spatially corresponds to the valleys of the article to be plated. A remote alignment fixture may be used to precisely align the shield apertures with the article valleys. Alternatively, a plurality of threaded alignment holes may be interspersed between a plurality of shield apertures, alignment being accomplished by threading a plurality of alignment screws through the threaded alignment holes and into the article valleys. A cylindrical embodiment of the electroplating shield having at least one spiralling aperture, is particularly suited for uniform plating of a spiral lobe rotor.

摘要： Apparatus for extracting core samples from the side walls of a subterranean well bore comprises an axial force generating tool insertable into the well with such tool carrying a stationary support rod and the movable element of such tool producing a movement of a housing surrounding the stationary support rod. Annular core forming tools are mounted on plural anvil plates disposed on sides of the stationary support rod and such tools are moved into penetrating relationship with the well bore side wall through association with a linkage between the movable housing, the anvil plates, and the stationary support rod. The movement of the axial force generating element is opposed by a resistance element. A limit to the maximum force applied to the core forming tools is provided by a shearable element series connected in the stationary support rod. Fluid dampening is provided for the decompression movement of the resistance element subsequent to the shearing of the stationary support rod to avoid dislodgement of the entrapped core samples by impact forces.

摘要： An apparatus and method for transporting a downhole tool in a borehole. A phase change material such as a shape memory metal is activated to engage the borehole and to transport the tool through the borehole. After the tool has been advanced in the borehole, the phase change material is deactivated to release from the borehole wall, and advances into position to continue the transport process. An extension can be engaged with the phase change material to extend the movement range of the phase change material. The phase change material actuator requires few moving parts and can be integrated with other tool components. The invention can operate in opposite directions within a borehole and can replace wellbore tractors and other locomotive tools.

摘要： Actuation of downhole tools is accomplished by inducing motion in the wireline. The downhole tool monitors such motion for predetermined patterns. Detection of a predetermined pattern actuates performance of a desired function. The pattern selected is sufficiently unique to avoid random or premature actuation. The tool may thus be actuated using ordinary nonconducting cable. In like fashion the tool can transmit stored information to the surface by a mechanical means such the resonant frequency of a mechanical signal in the cable.
