摘要： The present invention is directed to a helical drill configuration that allows substantially flat bottomed holes to be machined. At the cutting end of the body member, there are at least two cutting edges that are symmetrically oriented on opposing sides of the rotational axis of the drill. In an embodiment of the invention, first and second cutting edge portions form a continuous surface which provides strength and tool stability. The height of the second portions of each of the cutting edges remains relatively consistent along the horizontal for formation of a generally flat bottom hole. In the embodiment, a center point is defined by two sloped peak surfaces. A central straight chisel edge is formed by the intersection of the two sloped peak surfaces. The first cutting edge section extends from the chisel edge to the second cutting edge section. The first cutting edge section for both cutting edges is formed by symmetrically thinning the two peak surface. In the invention, stress at the center portion of the helical cutting tool is limited by the chisel edge and first sections of the cutting edge near the center portion having a balanced geometry. The balanced geometry of the helical drill also prevents the drill from wobbling and creating deviations in the hole being formed. The chisel edge may blend with a first curvilinear cutting edge and the first curvilinear cutting edge may also have a positive rake to promote cutting.

摘要： The present invention is directed to a helical drill configuration that allows substantially flat bottomed holes to be machined. At the cutting end of the body member, there are at least two cutting edges that are symmetrically oriented on apposing sides of the rotational axis of the drill. In an embodiment of the invention, first and second cutting edge portions form a continuous surface which provides strength and tool stability. The height of the second portions of each of the cutting edges remains relatively consistent along the horizontal for formation of a generally flat bottom hole.

摘要： A wellbore assembly includes a housing member, an outer wellbore member, and a second wellbore member, with an outer sensor located in the annulus between the outer wellbore member and the second wellbore member. The outer sensor can sense a condition of the annulus, such as pressure or temperature, and transmit data through a solid portion of the sidewall of the outer wellbore member to a signal receiver located on the housing member. In one embodiment, the signal receiver can transmit an electromagnetic field to inductively charge a power supply on the outer sensor.

摘要： A seal assembly between a wellhead housing having a bore and a casing hanger, has an inner seal leg for sealing against hanger and an outer seal leg for sealing against housing. An extension extends downward from outer seal leg and has a downward facing shoulder that rests on an upward facing shoulder formed on a nose ring. Connection connects seal ring to the nose ring with a lower portion of the nose ring resting on the upward facing shoulder of the casing hanger. Bellows are formed on the nose ring to increase lockdown capacity. Bellows have an inner surface that faces an outer profile of the hanger, and an outer surface on the bellow that faces the bore of the housing. When the bellows are axially collapsed, they expand radially outward and contract radially inward into the bore of the housing and the outer profile of the hanger.

摘要： A wellhead housing has a bore with a support shoulder, a ramp surface extending upward and outward from the support shoulder, and a recess extending upward from the ramp. A split, resilient load ring is carried in an initial position in the recess. A retractable and axially movable latch ring is carried in the recess above the load ring. A casing hanger has a profile that engages the latch ring as the casing hanger moves downwardly in the bore, causing the latch ring to move downward and pushing the load ring to the set position.

摘要： Devices and methods for selectively emplacing a wear bushing in a wellhead housing and removing it therefrom. A drill string-mounted running tool is used to selectively engage the wear bushing during emplacement and removal. The wear bushing need not be removed each time the drill string is tripped into or out of the well. In addition, the drill string may continue to be lowered after the wear bushing is landed since the running tools described can easily pass through the bushing.

摘要： A wellhead system comprising a high pressure housing having a retractable ring and a casing hanger having an activation ring configured to be engaged by the retractable ring when the casing hanger is lowered into the high pressure housing. An expandable load member is carried by the casing hanger into the high pressure housing. When the activation ring is engaged by the retractable ring, the activation ring is blocked from further downward motion. The activation ring and the body of the casing hanger cooperate with the load member to expand the load member outward into engagement with the high pressure housing as the casing hanger is lowered further into the high pressure housing. The outer surface of the load member and the inner surface of the high pressure housing are configured so that the high pressure housing supports the casing hanger when the load member is expanded into engagement with the high pressure housing.
