摘要： Fluid tube for sealing test in the BOP chamber. The test tube (1) used in the BOP chamber (C) resistance test step has its hollow structure filled internally and totally through a fluid (F) input (4). Thereby, wrapped by closing the drawers (G), after injection in the test fluid chamber (C), due to the filling fluid volume (F) internally and resulting air exhaustion into the hollow structure, the zest tube obtains a supplementary structure resistance against the pressure applied within the chamber (C), preventing unwanted distortions. The tube obtains an effective sealing due to the filling fluid volume (F) that exhausts the air within it, stopped internally with the couplings of the screwed pin (3) threads and the female thread (R) of the plug (TA) or test plug, preventing the test fluid into the chamber (C) to leak and enter its hollow structure. Therefore, the supplementary structure anti-distortion system, air absence inside the tube and test tube stoppage system avoid false pressure relieve into the chamber (C) to the sensors distributed therein, not detecting false leakages, making the BOP resistance analysis against potential oil/gas leakages precise during the probing procedure.

摘要： A system for detecting leakage in a pump includes a first pressure sensor, a second pressure sensor, multiple third pressure sensors, and a controller. The first pressure sensor is configured to output a pressure value associated with a suction manifold of the pump. The second pressure sensor is configured to output a pressure value associated with a discharge manifold of the pump. The third pressure sensors are configured to output a pressure value associated with the cylinders of the pump. The controller is disposed in communication with the first pressure sensor, the second pressure sensor, and the third pressure sensors. The controller is configured to determine amplitude of a leak, and a location of the leak in the pump on the basis of pressure values received from the first pressure sensor, the second pressure sensor, and the third pressure sensors.

摘要： Blowout preventers, fluid pressure systems and portions thereof may be tested for leaks by calculating an Apparent Compressibility Factor which is determined during initial pressurization of the system to the test pressure. The equivalent decay rate is calculated by measuring the amount of intensifying fluid required to be added to maintain the system at the test pressure level. The equivalent decay rate in psi per minute is then compared to the acceptable decay rate for the pressure level of the test to determine if the system passed the test.

摘要： An apparatus for detecting acoustic signals in housing is disclosed. The housing may be housing of a wellbore, riser, tubular or pipeline or the like for transporting fluids or housing of a vessel for storing fluids. The apparatus comprises a longitudinally extending tube having an internal surface and an external surface, a longitudinally extending fibre optic cable disposed within the tube, and one or more than one longitudinally extending outer fins radially extending outwards from and coupled with the external surface of the tube. The outer fin is configured to project towards the housing and allows fluid between the external surface of the tube and the housing when the apparatus is positioned in the housing. The apparatus may alternatively comprise a longitudinally extending fibre optic cable coated with a coating and one or more than one longitudinally extending outer fin radially extending outwards from and coupled with the coated fibre optic cable.

摘要： A seal assembly made up of multiple opposite oriented unidirectional seals. The assembly includes a dedicated test port for each of the unidirectional seals. Thus, a first test port may be directed at the first seal such that if the first seal leaks, the second seal is configured to collapse and allow a second test port coupled thereto to detect the leak of the first seal. By the same token, the first test port may be used to detect any leak in the second seal which is detectable as the first seal collapses as a result of the leak. This unique type of architecture allows for a reliable manner of testing a multiple seal assembly that may be prone to leaks from multiple directions, for example from either a bore or an annular side of a tubular. This renders the bidirectionally testable seal configuration beneficial for incorporation into downhole completions hardware such at the location of a test gauge secured to a carrier device.

摘要： A tool for testing a tubular has a shaft with a fluid passageway connecting a first port and one or more second ports. A sealing element seals against the tubular member. The shaft moves relative to the sealing sleeve between an open position in which the first port is in fluid communication with the second port and a closed position in which the sealing sleeve closes the first port. An anchor secures the sealing sleeve relative to the tubular member to permit the shaft to move from the open position to the closed position.
