Abstract: A system including a releasable connector having a housing and a split ring, and a complementary mandrel that is attachable/detachable from the connector, is provided. The mandrel is designed to be received into the housing such that a portion of the mandrel extends out of the housing for connection to a tool. The split ring is disposed in an annular space between the housing and the mandrel when the mandrel is in the housing. The split ring includes at least one set of threads and a detent formed on a radially internal surface, and the mandrel includes complementary threads. The threads on the split ring fully engage the complementary threads on the mandrel when the mandrel is in a particular axial position within the housing. The detent prevents the split ring from collapsing into engagement with the threads on the mandrel until the mandrel is in a desired axial position.

Abstract: A motorized release device for a downhole device includes one or more dogs disposed within a guide of the downhole device. The one or more dogs may move radially within the guide relative to a central axis of the motorized release device, such that the one or more dogs may move between an engaged position and a disengaged position. The motorized release device also includes a cam that is rotatable about the central axis, such that the cam may move between a locked position and an unlocked position. The cam may block the one or more dogs from moving to the disengaged position while the cam is in the locked position. The motorized release device may also include an electronics board. The electronics board may attach to a motor that rotates the cam between the locked position and the unlocked position.

Abstract: A method for assembly of a device is disclosed. The device comprises a quick connect apparatus that includes a first member having a male locking profile on an outer surface and a second member having a female locking profile on an inner surface. The method includes stabbing the second member onto the first member to fully seat the first member within the second member, rotating the second member relative to the first member to lock the male locking profile to the female locking profile, and engaging a second locking mechanism to restrict further rotation of the second member relative to the first member.

Abstract: A coupling system between tubular members such as tubing, pipes, casing and liner for location in a well bore in which the ends of each tubular have cooperating profiled sections. The profiled sections are arranged coaxially and a radially applied force is applied to form a metal to metal sealed connection. At least one profiled section includes a projection, the projection containing an overhang to the surface of the tubular member, the overhang locking with the opposing profile when the force is applied to provide a coupling with increased burst and collapse rating. Embodiments are provided of arrangements of overhangs such as oppositely directed overhangs and interlocking overhangs.

Abstract: A pipe connection includes a box that mates with a pin. A box slot extends through a side wall of the box at a point adjacent the rim for alignment with a pin slot formed on the pin. Each of the slots has a circumferential dimension and an axial dimension that is less than the circumferential dimension. The pin slot has a greater circumferential dimension than the box slot. A locking key has a pin section and a box section located within the pin slot and the box slot, respectively, when the key is installed. The pin section has teeth that bite into the pin slot. The key has a width substantially the same as the circumferential dimension of the box slot.

Abstract: A key assembly is press fit into an annular space between a box and pin member to resist relative rotation of the box and pin members. The key assembly includes wedge like members that contact one another along complementary tapered surfaces, and when in contact generate radial forces into the box and pin member to secure the connection between the box and pin. The outer wedge is inserted first into the annular space between the box and pin members, and has rows of elongate teeth that project radially outward into contact with an inner surface of the box member. Because the outer wedge is pushed radially outward against the box member rather than axially sliding therebetween, the teeth protrude into the surface of the box member thereby increasing the anti-rotation force created by the outer wedge.

Abstract translation: 钥匙组件压配合到箱体和销构件之间的环形空间中，以抵抗箱体和销构件的相对旋转。 钥匙组件包括楔形部件，楔形部件沿着互补的锥形表面相互接触，并且当接触时产生径向力进入箱体和销部件以固定箱体和销之间的连接。 外楔块首先插入箱体和销构件之间的环形空间中，并具有多排细长齿，径向向外突出而与箱体构件的内表面接触。 因为外部楔形件相对于箱体部件径向向外推动而不是在它们之间轴向滑动，所以这些齿部突出到箱体部件的表面中，从而增加了由外部楔形部件产生的抗旋转力。
