摘要： The invention provides a method of cutting a well casing located beneath a subsea wellhead (1), the method comprising the steps of: running a cutting tool through the wellhead (1) into the casing; securing the position of a motor (7) relative to the wellhead (1) so as to transmit rotary reaction forces from the motor (7) to the wellhead (1) or a fixture secured relative to the wellhead; and operating the motor (7) so as to rotate the cutting tool and thereby effect cutting of the casing. The invention overcomes the problems associated with prior art techniques of requiring the use of explosive charges or a drilling rig located above the wellhead.
摘要翻译：本发明提供了一种切割位于海底井口（1）下方的井套管的方法，该方法包括以下步骤：将切割工具穿过井口（1）运送到壳体中; 确保马达（7）相对于井口（1）的位置，以便将旋转反作用力从马达（7）传递到井口（1）或相对于井口固定的固定装置; 并且操作马达（7）以使切割工具旋转，从而实现壳体的切割。本发明克服了与要求使用炸药的现有技术相关的问题或位于井口上方的钻机。

摘要： A cutting tool for woodworking applications has a cemented carbide substrate and a hard layer bonded to the substrate at high temperature and high pressure, i.e. where diamond or cubic boron nitride is thermodynamically stable. The hard layer comprises polycrystalline diamond and/or polycrystalline cubic boron nitride, and a catalyst cobalt phase including adjuvant alloying materials for providing oxidation and corrosion resistance. Typical alloying elements include nickel, aluminum, silicon, titanium, molybdenum and chromium. The hard layer has an as-sintered surface and is only about 0.3 mm thick. An additional secondary phase including a carbide, nitride, carbonitride or oxycarbonitride of metals such as titanium may also be present in the PCD or PCBN layer.

摘要： A cutter element (62) having a substantially flat wear face and leading (64) and trailing (66) sections, wherein the leading section (64) is sharper than the trailing section (66). Sharpness is defined as either a smaller inside angle at the intersection of a pair of planes or as a smaller radius of curvature. The insert of the present invention experiences reduced stress on its trailing portion and therefore is less subject to extreme wear and failure. The present invention can be applied with particular advantage to heel row cutters, but can also be applied to cutters in other rows that primarily ream the borehole wall. The present cutter element can be constructed so as to have either a positive or negative rake angle at its leading section, or to have any of a variety of shapes, depending on the characteristics of the formation in which it is to be used.
摘要翻译：具有基本上平坦的磨损面和引导（64）和后部（66）部分的切割器元件（62），其中所述引导部分（64）比所述尾部部分（66）更尖锐。清晰度被定义为在一对平面的交点处较小的内角或较小的曲率半径。本发明的插入件在其尾部处经受较小的应力，因此较少遭受极度的磨损和破坏。本发明可以特别适用于后跟行切割器，但是也可应用于其他行中的主要钻孔的切割器。本刀片元件可以构造成在其前部具有正的或负的前角，或者根据其使用的地层的特性而具有各种各样的形状。

摘要： A rolling cone bit (10) having a gage row (80) and an adjacent nestled gage row (70) of cutter elements that are positioned on gage so as to divide or share the borehole corner cutting duty. The wear resistance, hardness, toughness and shape of the cutter elements in the adjacent rows (60, 70, 80) are optimized depending upon the type of cutting the respective rows perform, the characteristics of the formation being drilled and the drilling techniques being employed. In most applications, the nestled gage cutter elements (70) will have cutting surfaces that are more wear resistant or harder than the cutting surfaces of the gage cutter elements (80) which experience more bottom hole duty. The nestled gage cutter elements (70) engage the borehole wall with a negative rake angle for increased durability. Preferably, the nestled gage cutter elements (70) have continuously contoured and non-shearing cutting surfaces.

摘要： The present invention relates to tools for use in wellbores which are actuated by means of actuating balls. The invention provides a method of actuating a tool located in a wellbore, the method comprising the sequential steps of: (a) locating a frangible actuating ball (2) on a seat, the seat being provided in the tool for receiving the actuating ball (2); (b) pumping fluid down a tubing string attached to the tool so as to apply a force to the seat and thereby actuate the tool, the force being transmitted to the seat through the actuating ball (2); and (c) breaking the actuating ball (2) to permit fluid to flow through the seat. The invention has the advantage over the prior art of providing means for actuating a downhole tool with an actuating ball (2) so that the actuating ball (2) does not form an undesirable obstruction once the tool has been actuated.

摘要： Une soupape possède un passage (108, 114) au travers de la chapelle (10) de la soupape, s'étendant depuis la chambre (22) de la soupape jusqu'au chemin d'écoulement (12) de la soupape avec un organe d'intensification thermique (104, 204, 304) qui est disposé partiellement dans le passage et possède un alésage (110, 112; 210, 212; 310, 312) en registre avec le passage. Une partie de l'organe d'intensification thermique est en saillie à l'extérieur de la chapelle de la soupape. Soit une rondelle fusible (118) soit un élément d'espacement fusible (218, 318) est disposé dans l'alèsage dans cette partie de l'organe d'intensification thermique en saillie à l'extérieur de la chapelle de la soupape. La rondelle fusible (118) arrête l'écoulement de fluide au travers de l'alèsage, et donc bloque le passage, lorsque la rondelle est à l'état solide, et elle permet l'écoulement de fluide lorsqu'elle est à l'état liquide, ceci étant dû aux températures extérieures élevées. Un élément d'espacement fusible (218, 318) supporte une rondelle mobile (216, 316) pourvue de joints d'étanchéité (232, 234 ou 332, 334) disposés dans l'alèsage pour assurer l'étanchéité lors de l'écoulement du fluide au travers de l'alésage et donc au travers du passage dans des conditions de températures normales de fonctionnement. L'élément d'espacement fusible fond à des températures élevées et permet par conséquent à la rondelle mobile de glisser dans l'alésage pour ouvrir l'alésage et permettre l'écoulement de fluide au travers du passage. De plus, les joints d'étanchéité de la rondelle mobile se désintègrent et permettent la communication du fluide même lorsque l'accès direct au passage est encore bloqué par la rondelle mobile. Ces caractéristiques permettent le déplacement de la pression interne de la soupape et évitent d'endommager la soupape.
