摘要： This invention comprises a system for measurement of temperature and pressure in oil wells. It comprises a single hybrid mandrel housing a pressure and temperature double optical sensor, capable of measuring temperature and pressure both in the ring and in the production tubing of an oil well and an insertable venturi tube inserted in the direction of a pressure differential optical sensor, capable of taking flow rate measurements, the installation aspects of which are substantially simplified. With the proposed construction, it is possible for one single hybrid mandrel (30) to read the pressure and temperature in the ring and tubing and the flow rate. With this, changes of flow rate are also possible, without the need to stop production for long periods for the hybrid mandrel (30) to be replaced, the mere replacement of the insertable venturi (12) sufficing, by means of an insertion and extraction tool (17), which is an operation requiring a much shorter time.

摘要： A method of freeing a pipe stuck in a subterranean well can include determining a location of a portion of the pipe stuck in the well, and penetrating and/or heating a sidewall of the pipe portion with a beam of light. A system for freeing a pipe stuck in a subterranean well can include a tool deployed into a portion of the pipe stuck in the well by a differential pressure from a wellbore to a formation penetrated by the wellbore. A beam of light emitted from the tool penetrates the pipe portion. Another method of freeing a pipe stuck in a subterranean well can include determining a location of a portion of the pipe which is biased against a wall of a wellbore by differential pressure, and directing a beam of light to the pipe portion.

摘要： A system for coupling a pipe segment to a pipe string is provided that includes a top drive assembly having an output shaft; and a pipe running tool coupled to the top drive assembly and rotatable by the output shaft of the top drive assembly. The pipe running tool includes an internal gripper for insertion within an internal diameter of the pipe segment and a tapered slip cone section, which slidably receives corresponding tapered surfaces of a plurality of slips, such that a vertical force on the slips causes the slips to move radially outwardly into gripping engagement with the internal diameter of the pipe segment, and wherein the vertical force applied to the slips is sufficient to allow the gripping engagement of the slips with the internal diameter of the pipe segment to transmit a torque from the top drive output shaft to the pipe segment.

摘要： An apparatus for handling tubular goods which includes an elongate body having a coupling end adapted for mating engagement with a tubular good. The coupling end includes a structural member (4), a flexible cylindrical (3) cage and a pressure member. Longitudinal strips (80) joined at their opposed ends (82) form the cage coaxial with and connected to the structural member (4) of the body. The coaxial pressure member is disposed in an annulus between the structural member and the cage. The pressure member is adapted to cause radial displacement of the cage, thereby exerting a gripping force to maintain the mating engagement between the tubular good and the coupling end enabling a transfer of force between the body and the tubular good.

摘要： To obviate the need for hydraulic lines from the surface, external water pressure is used to compress a seal member (20) and form a seal with a surrounding pipe (30). Valve (24) is opened at depth to allow water to act on a piston (16), moving it within a chamber (14) so as to compress the seal member (20). A second valve (29) may be opened so that water acts on the opposite end of the piston (16) to release the seal member (20).
