摘要： Float equipment is constructed to have the check valve in an offset and/or skewed position with respect to the centerline of the tubular housing that is part of a string. The design is applicable to poppet type check valves as well as flapper type valves that are actuated with a flow tube. The off center and/or skewed position of the valve components allows the cutting structure on a drill bit, rather than the nozzle area on the bit bottom to make intimate contact with the valve components to accelerate the milling one of the assembly and the making of additional hole beyond the recently cemented string.

摘要： A drill bit for drilling casing in a well bore. The drill bit is constructed from a combination of relatively soft and relatively hard materials. The proportions of the materials are selected such that the drill bit provides suitable cutting and boring of the well bore while being able to be drilled through by a subsequent drill bit. Methods of applying hard materials to a soft material body are provided.

摘要： An apparatus to protect the mounting area of casing when subsequently attaching a tubular is disclosed. A sleeve that defines a sealed cavity having a loose incompressible material inside covers the mounting location on the casing. The cementing of the casing takes place through the sleeve. After the cementing, the sleeve is drilled out and the incompressible material is removed to the surface with the drill cuttings. A tubular is inserted in the casing and is preferably expanded into sealing contact with the mounting location on the casing. At the end of expansion, the run in shoe on the tubular is retrieved.

摘要： An apparatus and methods for preventing the accumulation of unwanted materials in an enlarged inner diameter portion of a casing or housing. In one aspect of the invention, a sleeve is disposed in the housing to isolate an annular area defined by the outer surface sleeve and the wall of the enlarged inner diameter portion. The sleeve prevents unwanted materials from being disposed in the annular area. The sleeve can later be expanded into the enlarged inner diameter portion, removed from the wellbore or destroyed. In another aspect of the invention, the sleeve is provided and disposed to cover the enlarged inner diameter portion. By covering the enlarged inner diameter portion, unwanted material is prevented from accumulating at said portion and from interfering with the expansion of the next casing into said portion to form a monobore. The sleeve can be made from materials that are dissolvable, elastically deformable, or retrievable.

摘要： A flightless rock auger For drilling postholes through rock without the use of hydraulic pressure. The rock auger has a plurality of teeth extending downwardly at a selected angle from the edge of a cylinder connected to a quick connect shaft. The rock auger is utilized for drilling through rock and used in combination with a conventional flighted auger used for drilling postholes in dirt and clay. During a posthole drilling operation, the rock auger is substituted for the flighted auger as needed for drilling through and remove rock or other hard material such as concrete fron the posthole. The rock auger is designed for use at very low revolutions per minute and utilizes only the weight of the auger and shaft and does not require any additional hydraulic pressure for cutting a circular hole through the rock and forming a plug which is to be lodged in the cavity of the rock auger cylinder to be removed from the posthole. The quick connection shaft enables the conventional flighted auger to be quickly substituted for the rock auger to facilitate fast removal of soft dirt from the posthole. The rock auger provides an alternative method for utility companies to drill postholes for electric poles, telephone poles, pilings, and the like without the use of explosives, thereby providing for safer excavation.
摘要翻译：无螺旋钻石用于通过岩石钻孔而不使用液压。岩石螺旋钻具有从连接到快速连接轴的气缸的边缘以选定角度向下延伸的多个齿。岩石钻被用于钻岩石，并与用于在污垢和粘土中钻孔的常规螺旋钻相结合使用。在钻孔操作期间，根据钻孔通过并移除岩石或其他硬质材料（例如后孔的混凝土），代替螺旋钻代替螺旋钻。岩石钻机设计用于每分钟转数非常低的转速，仅使用螺旋推运器和轴的重量，不需要额外的液压压力来切割通过岩石的圆形孔，并形成一个将被放在岩石螺旋钻缸的腔体将从后孔中取出。快速连接轴使得传统的螺旋钻可以快速地代替岩石钻，以便于从柱孔中快速去除软污垢。岩石钻机为公用事业公司提供了一种替代方法，无需使用爆炸物就可以对电杆，电话杆，打桩等进行钻孔，从而提供更安全的挖掘。

摘要： An overburden drilling device includes a drill bit body, a percussion element for applying impacts to the body, and a casing attached to the body. The casing is connected to the drill bit body by a casing shoe. The casing shoe and the drill bit body are interconnected by radially overlapping walls so that the drill bit body pulls the casing along during a drilling operation while rotating relative thereto. A wedge-shaped member is provided around the casing close to a rear end of the casing shoe so as to facilitate removal of the drilling equipment from a bore.

摘要： Well apparatuses with device for preventing their relative rotation with respect to adjacent well apparatuses and anti-rotation devices for well apparatuses, including, but not limited to, plugs, float shoes, float collars, jars, and clutch devices for packers. In one embodiment self-aligning non-rotation devices are provided with body members having protrusions extending from recesses therein, the protrusions and recesses configured and disposed so that two opposed devices which initially misalign will co-act to align themselves. In another embodiment an intentional "sloppy fit" is provided between two opposed devices to facilitate device contact and co-action. In various embodiments unwanted separation of two devices is prevented due to the configuration of protrusions. In one embodiment a non-rotation device has a main member with a recess on which are disposed a plurality of teeth with a load member adjacent the teeth for bearing a load put on the device and for isolating the teeth from the load, the teeth extending beyond the recess. In one embodiment the teeth are configured, disposed, and profiled to facilitate their interengagement with other teeth and to contain between them foreign objects which might impede proper interengagement. In various embodiments plugs or other equipment are provided with such anti-rotating devices. In various embodiments the load member is a continuous circular ring disposed about the apparatuses outer periphery or around the opening of a channel through the device. The load members may be non-continuous upstanding members.

摘要： The present specification describes and claims a downhole casing shearer for use in drilling bore holes. The casing shearer comprises an elongate, generally cylindrical sub-member which is connected between a drilling bit and a drill rod string and which engages within a hollow cylindrical shearer, the trailing end of the shearer being connected to a conventional bore hole liner, so that the shearer may rotate about its longitudinal axis with the liner stationary. The sub-member and shearer are interlocked by a releasable locking mechanism which prevents relative rotation therebetween but which allows both for the axial drilling pressure to be applied to the shearer and the shearer to be lifted, and for the drilling bit, sub-member and rod string to be lifted through the liner leaving the shearer and liner in the bore hole, when the locking mechanism is released.
