摘要： A flexible steering sub is disclosed for flexible drilling of horizontal oil and gas wells, horizontal storage wells, geothermal drilling for electric power generation; earth sciences study of and monitoring of earth movement with respect to fault movement; environmental science cleaning up of inaccessible polluted areas; coring to test rock strength prior to large scale constructions such as dams; introduction of chemicals for solution mining logging while drilling short radius well bores, and the like. The flexible sub comprises an elongated housing having a plurality of housing sections connectable at one end to an orientation sub for a PDM drill and connectable at the other end to a wire line connector. An electronics assembly including guidance directional guided sensors, directional probe and logging while drilling probe is positioned in a plurality of the housing sections, interconnected electrically, and connected at one end to the wire line connector. An articulated sinker bar and an articulated housing section spaced along the length of the housing and operable to bend in preference to bending of the housing sections containing the electronics assemblies. The steering sub is operable during drilling to bend along its length at the said articulated sinker bar and said articulated housing section on a short radius without bending the electronics assembly.

摘要： A system of apparatus for arcuate drilling into the earth is disclosed which comprises a drill string extending into a well bore in the earth and a fluid operated drill motor and drill bit operated thereby secured on the bottom end of the drill string. The drill motor is connected at its upper end to the drill string and at its lower end to the drill bit for rotating the drill bit independently of rotation of the drill string. The drill motor has a tubular drive section housing constructed of non-magnetic material, preferably a Beta-C titanium alloy containing titanium, aluminum, vanadium, chromium, zirconium and molybdenum in the proportions Ti-3Al-8V-6Cr-4Zr-4Mo. The longitudinal axis of the drill motor housing has its upper and lower ends angularly displaced from the longitudinal axis of its central portion end for directing the axis of rotation of the drill bit such that it is angularly displaced from the axis of the drill string for effecting a curved path for the wellbore. An orienting/circulating/float sub constructed of non-magnetic material, preferably Beta-C titanium alloy, connected above the drill motor. A drill collar constructed of non-magnetic material, preferably Beta-C titanium alloy, is connected to the upper end of the orienting/circulating/float sub. The drill collar may be of a one-piece Beta-C titanium alloy with integral threaded ends or may have separate threaded end pieces of steel or Beta-C titanium alloy welded thereon. A survey tool is positioned in and surrounded by the orienting/circulating/float sub. A drilling rig, instruments and controls positioned on the earth surface and connected by wire lines and a wet connect to the survey tool. The structure and configuration of the respective components cooperate to facilitate bending through a radius of curvature as short as 20 feet.

摘要： An apparatus and method for manufacturing a down hole tool that reduces manufacturing costs and enhances the tool's performance. A belted mold assembly includes a casting assembly, a belt assembly, and a mid-belt. The belted mold assembly is used to fabricate a casting that allows for a larger diameter blank to be used which displaces the more expensive casting material and for using a smaller outer diameter thin-walled mold. The casting assembly is disposed within the belt assembly and the mid-belt is loaded in the volume created between the casting assembly's outer surface and the belt assembly's inner surface. The mid-belt provides a bracing for the casting assembly during the casting process. Optionally, a cap can be disposed on top of the blank for preventing metallurgical bonds from forming between the binder material and the upper portion of the blank. This allows for the excess binder material to remain high in purity so that it can be reprocessed. The cap can be used with the belted mold assembly or with a casting assembly known in the prior art.
摘要翻译：一种用于制造井下工具的装置和方法，其降低制造成本并提高工具的性能。带式模具组件包括铸造组件，带组件和中间带。带式模具组件用于制造允许使用更大直径坯料的铸件，其移动更昂贵的铸造材料和使用更小的外径薄壁模具。铸造组件设置在带组件内，并且中间带被装载在铸造组件的外表面和带组件的内表面之间产生的体积中。中间带在铸造过程中为铸造组件提供支撑。任选地，盖可以设置在坯料的顶部上，以防止在粘合剂材料和坯料的上部之间形成冶金结合。这允许多余的粘合剂材料保持高纯度，使得其可以被再加工。盖可以与带状模具组件或现有技术中已知的铸造组件一起使用。

摘要： A casing end tool has a bowl-like (or cup-like) body defined by a wall having an outer convex surface and an inner concave surface opposite of the outer convex surface. The bowl-like body has a center axis. The inner concave surface is non-axisymmetric with respect to the center axis, while the outer convex surface is axisymmetric with respect to the center axis. The non-axisymmetric configuration is provided in one implementation through the presence of a set of raised boss or land structures formed on the inner concave surface. In another implementation, the non-axisymmetric configuration is provided by channels formed in the inner concave surface
