WELL TESTING SYSTEM AND METHOD FOR CHECKING PRESSURE IN SYSTEM COMPONENTS Russian patent published in 1998 - IPC

FIELD: oil and gas production industry. SUBSTANCE: system has ball valve with multiple fluid medium lines connected to it. Ball valve is located between inflow fluid line and outflow line. Each fluid flow line is connected with corresponding component of well testing equipment designed for determined pressure value. Pressure safety means are located in each medium flow line between aforesaid component of equipment and aforesaid ball valve. Each pressure safety means is brought into operation when medium flow pressure in line exceeds preset value so as to pass medium flow to ball valve. Ball valve can be brought into operation in response to reaction of one of medium flow pressure safety means which passed medium flow through itself. In this case ball valve comes to open position and remains in open position so that mixture of liquid and gas from productive bed flows through ball valve to outflow line. EFFECT: high efficiency. 11 cl, 3 dwg
