    摘要: A method of controlling at least one of a flow rate or pressure of an injected fluid includes receiving a measured value indicative of the at least one of the flow rate or the pressure of the injected fluid, and determining a control mode for controlling the at least one of the flow rate or the pressure. The method further includes controlling the at least one of the flow rate or the pressure of the injected fluid according to the selected control mode including: determining a command signal to be communicated to a field device, and communicating the command signal to the field device.

    摘要: Methods and apparatus for calibrating controllers for use with wells are disclosed. An example method includes moving a polished rod of a pumping unit through a first cycle of the pumping unit using a motor and determining first pulse count values of the motor through the first cycle using a first sensor at first times. The first times are substantially equally spaced. The method also includes determining first position values of the polished rod through the first cycle using a second sensor at the first times and associating the first pulse count values with respective ones of the first position values to calibrate a processor of the pumping unit.

    摘要: A system constructs a hierarchy for field devices communicatively coupled to a remote terminal unit (RTU) by retrieving device information from field devices, caching the device information in the memory of the RTU, storing device identities in the memory of a host machine, and obtaining the device information at the host from the RTU in response to subsequent user requests to build the hierarchy, without re-sending commands to retrieve the device information directly to the field devices.

    摘要: Methods and apparatus to determine parameters of a pumping unit for use with wells are disclosed. An example apparatus includes a housing and a processor positioned in the housing. The processor is to determine a first load on a polished rod of a pumping unit, to estimate a first torque of a motor of the pumping unit, and determine a first torque factor for the pumping unit. The processor is to, based on the first load, the first torque, and the first torque factor, determine a phase angle of a counterbalance of the pumping unit or a moment of the counterbalance.
