摘要： A dual seat valve assembly includes a first valve and a concentric second valve which together form a tight seal valve assembly. The valves open and close sequentially. A quick disconnect rupture disc assembly may be used in conjunction with the valve assembly to provide a required safety feature for testing high pressure fluid ruptures that include a dump valve.

摘要： A method and apparatus for testing blowout preventers for leaks involves maintaining a constant pressure in the portion of the blowout preventer to be tested. A sensor is connected to a controller for maintaining a constant pressure within the blowout preventer. Any amount of fluid introduced into or removed from the blowout preventer in order to maintain constant pressure is measured and is an indication of the leak rate in the blowout preventer. Additionally vibration instrumentation may be used to detect the location and amplitude of vibrations emitted by the test fluid passing from a high pressure regime to the low pressure regime across a leak path.

摘要： A method of pressure testing a closed hydraulic system for leaks includes heating or cooling pressure intensification fluid before it enters the closed hydraulic system under pressure. The closed hydraulic system may be for example a blowout preventer for an oil/gas well, a manifold system or tubulars. The intensification fluid is heated or cooled to a temperature at or near the temperature of the fluid within the closed hydraulic system.

摘要： A method and apparatus for testing a blowout preventer which includes a plurality of safety devices and an assembly of fluid control valves that are remotely actuatable to an open and closed position for controlling flow of drilling fluids into a well includes a hydraulic power unit control station for remotely and selectively actuating one or more safety devices and fluid control valves to a test orientation. A hydrostatic test system supplies fluid under first and second test pressure and documents any pressure loss due to fluid leaks within a closed system.

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.
