Manifold implemented in multi-channel system for controlling flow of fluids in oil well

Abstract

Manifold for controlling flow of fluids in multi-channel system deployed in oil well including an orifice formed between inlet ports and outlet ports. The orifice receives fluid through inlet ports and is in fluid communication with a pressure system and tank. The manifold includes a check valve connecting the orifice and receiving/controlling flow of fluid. The manifold includes a gas charged accumulator adapted to store hydraulic energy generated at an inlet of the gas charged accumulator when pressure of the fluid becomes greater than a precharge pressure. The manifold includes a flow control valve connecting the check valve and gas charged accumulator. The flow control valve and gas charged accumulator control the opening of the check valve and prevent improper operation of the manifold. The gas charged accumulator dumps fluid into the tank quickly when the flow control valve moves out of its intended position during a failure of drilling operation.
