摘要： Disclosed embodiments include systems and methods for improving the accuracy of bottom hole pressure control. One example embodiment includes a torque and drag model that calculates the elasticity of the drill string, which is included in a managed pressure drilling control system. The addition of the torque and drag calculations provide more accurate surge/swab effect calculations based on pipe movement corrected for elasticity effects. The results of these calculations will be used in a real-time hydraulics model to determine a setpoint pressure which will be utilized by a MPD choke system. Further, the real-time torque and drag models are calibrated to actual hole conditions in real-time using survey, temperature, pressure and downhole tool data to calculate friction factors in a wellbore.

摘要： A drilling device with improved fuel efficiency, reduced impact on the environment, and the like is provided. Specifically, a drilling device performs unload control of a compressor when an engine starts up, and brings the air pressure in an air tank to a first air pressure. Moreover, the air pressure in the air tank is kept at the first air pressure while the engine is driven and a flushing mechanism is not driven. In addition, unload control of the compressor is performed when the flushing mechanism starts up, and the air pressure in the air tank is increased to a second air pressure that is higher than the first air pressure. For example, the first air pressure and the second air pressure are a low pressure (0.5 MPa) and a high pressure (1.03 MPa), respectively.

摘要： A managed pressure drilling (MPD) operation may use an inverse model in conjunction with a hydraulic model and real-time drilling conditions and parameters as inputs to determine a wellhead pressure set point corresponding to a desired bottomhole pressure. For example, while drilling a wellbore penetrating a subterranean formation with a drilling system, measured data including a wellhead pressure may be acquired. A model may then be executed that applies a hydraulic model to an a priori model estimate vector to produce predicted data; converts the measured data to a measured data vector; applies a randomized maximum likelihood algorithm to the a priori model estimate vector, the predicted data, and the measured data vector to produce an a posterioiri model estimates; and applies the hydraulic model to the a posterioiri model estimates to produce an a posteriori prediction and a calculated wellhead pressure set point corresponding to a desired bottomhole pressure.

摘要： This Application addresses maintaining a hydrostatic pressure exerted on a wall of a wellbore in different intervals of the wellbore. This is done by flowing a liquid through at least a pressure regulator in each interval, and wherein each pressure regulators regulates the amount of pressure exerted by the liquid on the wall of the wellbore. The amount of pressure may be maintained for a specific period of time. The wellbore is part of a soft subterranean formation.

摘要： A choke valve assembly, system, and method can be used with a drill string in a wellbore to aid in controlling the bottom hole pressure during drilling of the wellbore. The choke valve assembly can have a primary choke and one or more supplemental chokes, where these choke valves each have a controllable range relative to the flow and pressure of drilling fluid passing through the assembly. A control unit can automatically actuate the primary choke and one or more supplemental chokes in order to both maintain the choke valves within their controllable ranges and concurrently maintain a consistent boom hole pressure in the connected wellbore.
