  • Patent number: 10337267
    Abstract: The invention relates to the field of stratum drilling, and in particular to a control method and a control device for drilling operations. The control method comprises: detecting whether an overflow occurs in a well; controlling the wellhead back pressure based on a preset bottom hole pressure when no overflow occurs in the well, in order to keep the bottom hole pressure stable; and performing a shut-in operation and controlling the wellhead back pressure based on the increase in fluid discharge returned from an annulus of the well when an overflow occurs in the well, so as to keep the bottom hole pressure stable and prevent the gas in the stratum from continuing to invade into the drilling fluid during the process that the overflow drilling fluid is discharged from the bottom of the well.

  • Publication number: 20190073918
    Abstract: A method includes receiving state information of a virtual movable object in a simulated movement from a movement simulator associated with a movable object and determining movement information for the simulated movement by associating the state information with context information. The state information includes information identifying a location of the virtual movable object in a virtual space. The context information includes information identifying a location of the user terminal, which is at a different location than the movable object in a real space. The method further includes displaying the simulated movement on a display associated with the user terminal based on the movement information, and receiving control data to control the simulated movement in the virtual space using the user terminal when the movable object is in simulation and to control movement of the movable object in the real space when the movable object is in real operation.
