  • Regulating drilling fluid pressure in a drilling fluid circulation system
    Patent number: 10036218
    Abstract: A system and method are disclosed for regulating drilling fluid pressure in a drilling fluid circulation system. In one embodiment, a drilling fluid circulation system includes a processor (110) connected to a pressure relief device (104), which is connected to piping between a discharge of a drilling fluid pump (30) and an inlet of a drill string (31). The processor receives pressure measurement signals representative of a pressure of the drilling fluid in the piping and flow parameter signals representative of a flow of the drilling fluid through the piping. From the pressure measurement signals and the flow parameter signals, the processor determines that a target pressure parameter of the drilling fluid in the piping is not satisfied. In response, the processor lowers the pressure of the drilling fluid in the piping until the target pressure parameter is satisfied by at least partially opening the pressure relief device.
