摘要： An apparatus for cutting and/or milling of tubulars in a wellbore, especially using coiled tubing. An elongated main body has a longitudinal bore, with a piston slidably positioned in the bore. The piston is connected to one or more operating arms which are rotatably connected to the main body. The connection between the piston and the operating arms may be a pinned connection or a geared connection, both of which provide for a positive connection between the piston and the operating arms. Cutter bases are connected to the cutter arms, with a number of cutters mounted to the cutter bases. Fluid flow down the coiled tubing and through the main body bore pushes the piston downwardly, opening the operating arms and cutter bases and permitting the apparatus to be pulled up into the lower end of a tubular string for cutting and/or milling.

摘要： A casing mill having a main body with cutter bases with cutters mounted on the cutter bases. The cutter bases are moved radially by operating arms which are rotatably attached to the main body, which are in turn moved by an operating mechanism in response to fluid flow through. One or more of the operating arms are extended to form a cutout arm, which enables cutting an initial window in a casing string, from which milling can continue. The operating arms are mounted to the main body by pins, which are held in the main body by a pin retaining arrangement.

摘要： A casing mill for downhole casing milling has multiple elongated cutter bases hingedly connected to a main body by a plurality of positioning arms. An operating mechanism within the main body of the casing mill, actuated by fluid flow, moves the cutter bases to an extended position. Multiple cutters fixed to the cutter bases are then positioned to engage a casing end surface. Preferably, the cutters are arranged in vertically spaced apart rows, such that when one row is worn out in the milling process a visual indication is seen at the surface, as the casing mill drops to the next row of cutters.

摘要： A method and apparatus for visual inspection of wellbore environments wherein a real-time video feed is received at the earth's surface from a camera assembly positioned downhole within a wellbore. The camera system is capable of recording high quality video images in full streaming quality and speed in either color or black and white bands, simultaneously transmitting live visual images to the earth's surface, and accepting and acting upon commands from the surface (including, without limitation, recording programmability).

摘要： A wireless communication assembly permits convenient and effective communication between down hole logging and/or data storage tools conveyed via non-conductive wireline and surface equipment, including while such tools are situated within a lubricator, wellhead or other surface equipment. Data acquired by a down hole logging or data storage tool is transmitted to a wireline-conveyed communication assembly, and then wirelessly transmitted to a surface data communication assembly. Thereafter, such data can then be acquired, displayed and/or downloaded via an external data port on said surface data communication assembly using a wired or wireless connection.

摘要： A bidirectional telemetry system for data transfer over relatively long distances such as, for example, within an oil or gas well. Data is transferred via cable such as a single conductor cable used for the transmission of various types of logging data including, but not limited to, video signals, pressure and temperature information. A video or other signal can be electronically converted into an amplified current modulated telemetry equivalent, transmitted along a cable having a varied impedance characteristics, and electronically converted back into a compliant voltage modulated composite video standard.

摘要： A downhole release mechanism for a drillstring. A first, uphole section and a second, downhole section comprise longitudinal bores and are rotationally locked together via a spline. A collet assembly is connected to the first section, with collet fingers extending into the bore of the second section when the first and second sections are joined. The collet fingers are biased outwardly, and an external shoulder on the collet fingers mates with an internal shoulder in the second section, locking the sections together. A piston is slidably disposed in a bore of the collet, and spring biased uphole. Fluid flow moves the piston to a downhole position, in which the collet fingers are held outwardly and the shoulders locked together. With fluid flow stopped, the piston moves uphole, and sufficient tension on the mechanism shears shear screws and snaps the collet fingers out the internal shoulder, releasing the mechanism.
