摘要： A wellbore seismic source includes a sparker electrically coupled to a power source. The sparker is disposed in a pressure-sealed canister, wherein the canister is at least partially filled with liquid. At least one of the pressure of the liquid and the energy discharged by the power source through the sparker is selected to cause emission of acoustic energy at a selected frequency.

摘要： A superabrasive fracture resistant compact is formed by depositing successive layers of ceramic throughout the network of open pores in a thermally stable self-bonded polycrystalline diamond or cubic boron nitride preform. The void volume in the preform is from approximately 2 to 10 percent of the volume of the preform, and the average pore size is below approximately 3000 nanometers. The preform is evacuated and infiltrated under at least about 1500 pounds per square inch pressure with a liquid pre-ceramic polymerizable precursor. The precursor is infiltrated into the preform at or below the boiling point of the precursor. The precursor is polymerized into a solid phase material. The excess is removed from the outside of the preform, and the polymer is pyrolized to form a ceramic. The process is repeated at least once more so as to achieve upwards of 90 percent filling of the original void volume. When the remaining void volume drops below about 1 percent the physical properties of the compact, such as fracture resistance, improve substantially. Multiple infiltration cycles result in the deposition of sufficient ceramic to reduce the void volume to below 0.5 percent. The fracture resistance of the compacts in which the pores are lined with formed in situ ceramic is generally at least one and one-half times that of the starting preforms.
摘要翻译：通过在热稳定的自结合多晶金刚石或立方氮化硼预成型体中的开孔的网络中沉积连续的陶瓷层来形成超耐磨断裂的压块。预制件中的空隙体积约为预制件体积的约2％至10％，平均孔径低于约3000纳米。将预成型件用至少约1500磅/平方英寸的压力抽真空并用液体预陶瓷可聚合前体渗透。前体在等于或低于前体沸点的条件下浸入预制件中。将前体聚合成固相材料。将多余物从预成型体的外部除去，并将聚合物热解以形成陶瓷。该过程至少重复一次，以便实现原始空隙体积的90％以上的填充。当剩余的空隙体积下降到约1％以下时，压实体的物理性能如抗断裂性能显着改善。多次渗透循环导致沉积足够的陶瓷以将空隙体积降低至0.5％以下。孔内衬有形成的原位陶瓷的压块的耐断裂性通常为起始预制件的抗压强度的至少一倍。

摘要： A cutting element and a method for forming a cutting element is described and shown. The cutting element includes a substrate, a TSP diamond layer, a metal interlayer between the substrate and the diamond layer, and a braze joint securing the diamond layer to the substrate. The thickness of the metal interlayer is determined according to a formula. The formula takes into account the thickness and modulus of elasticity of the metal interlayer and the thickness of the TSP diamond. This prevents the use of a too thin or too thick metal interlayer. A metal interlayer that is too thin is not capable of absorbing enough energy to prevent the TSP diamond from fracturing. A metal interlayer that is too thick may allow the TSP diamond to fracture by reason of bending stress. A coating may be provided between the TSP diamond layer and the metal interlayer. This coating serves as a thermal barrier and to control residual thermal stress.
摘要翻译：描述和示出切割元件和形成切割元件的方法。切割元件包括基底，TSP金刚石层，在基底和金刚石层之间的金属中间层以及将金刚石层固定到基底上的钎焊接头。根据公式确定金属中间层的厚度。该公式考虑了金属夹层的厚度和弹性模量以及TSP金刚石的厚度。这防止了使用太薄或太厚的金属夹层。太薄的金属中间层不能吸收足够的能量以防止TSP金刚石破裂。过厚的金属中间层可能会导致TSP金刚石因弯曲应力而断裂。可以在TSP金刚石层和金属中间层之间提供涂层。该涂层用作热障，并控制残余热应力。

摘要： A drill bit for connection on a drill string has a hollow tubular body with an end cutting face provided with a tungsten carbide coated surface and an exterior peripheral stabilizer surface with cylindrical sintered carbide inserts positioned therein. Nozzle passages extend from the interior of the bit body through the cutting face for receiving a removable and interchangeable nozzle member therein. The cutting face has a plurality of recesses therein which receive, by an interference fit, a plurality of cutting elements of the type known as STRATAPAX, consisting of a cylindrical stud having an angular supporting surface with a cutting disc bonded thereon consisting of sintered carbide having a cutting surface of polycrystalline diamond. The recesses in the cutting face have milled offset recesses adjacent to the edges thereof which are sized and positioned to permit the cutting discs to be partially recessed and to restrain the cutting elements from rotation during use. The cutting face is coated with tungsten carbide to a thickness of 0.012-0.040 in. by means of a high-velocity, high-temperature plasma coating process after the cutting elements are assembled in the bit body. This process coats the steel bit body with tungsten carbide without coating or otherwise affecting the cutting inserts. The coating is metallurgically bonded to the steel bit body and protects against wear during drilling for periods of several hundred hours.

摘要： A drill bit for connection on a drill string has a hollow tubular body with an end cutting face and an exterior peripheral stabilizer surface with cylindrical sintered carbide inserts positioned therein and a novel arrangement for securing replaceable nozzles. Nozzle passages extend from the interior of the bit body through the cutting face for receiving a removable and interchangeable nozzle member therein. A portion of the length of each passage is threaded and the remainder of the passage is enlarged and of a smooth bore. The nozzle member is formed of wear-resistant hard metal, e.g. carbide, and has a metal sleeve brazed thereon with male threads operable to be fitted in the threads in said nozzle passage. The nozzle member is threadedly secured in place during installation and optionally further secured against unscrewing and additionally protected against wear or erosion by a metal or hard metal, e.g. carbide, retaining ring having an interference fit in the smooth portion of the nozzle passage. The shape of the hard metal nozzle member protects the entire nozzle assembly, and particularly the threaded metal sleeve, from erosion produced by abrasive drilling fluids. The cutting face supports suitable cutting means, preferably diamond cutting elements. The replaceable nozzles with threaded exteriors and protecting retaining rings may be used with other types of drill bits, e.g. roller cone bits, but are particularly useful with diamond bits because of the close proximity of the nozzles to the cutting surface in diamond bits which results in a very high wear rate.

摘要： A method for operating an impulsive type seismic energy source in a firing sequence having at least two actuations for each seismic impulse to be generated by the source. The actuations have a time delay between them related to a selected energy frequency peak of the source output. One example of the method is used for generating seismic signals in a wellbore and includes discharging electric current through a spark gap disposed in the wellbore in at least one firing sequence. The sequence includes at least two actuations of the spark gap separated by an amount of time selected to cause acoustic energy resulting from the actuations to have peak amplitude at a selected frequency.
