  • 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.

  • Patent number: 10329860
    Abstract: A method of drilling a subsea wellbore includes drilling the subsea wellbore and, while drilling the subsea wellbore: measuring a flow rate of the drilling fluid injected into a tubular string; measuring a flow rate of returns; comparing the returns flow rate to the drilling fluid flow rate to detect a kick by a formation being drilled; and exerting backpressure on the returns using a first variable choke valve. The method further includes, in response to detecting the kick: closing a blowout preventer of a subsea pressure control assembly (PCA) against the tubular string; and diverting the flow of returns from the PCA, through a choke line having a second variable choke valve, and through the first variable choke valve.

  • Patent number: 10301899
    Abstract: A containment device for containing leakage from a stuffing box is provided. The containment device can have a base defining an interior space, a structural member positioned substantially vertically with an interior passage sized to allow a polish rod to pass through and a lid. The containment device can be adapted for connection to the stuffing box so that a bottom of the structural member rests on the stuffing box when the containment device is installed on the stuffing box. The containment device can be installed by removing a dust cap from the stuffing box and attaching the containment device to a top of the stuffing box with the interior passage aligning with the stuffing box. The dust is installed on top of the lid and the lid placed on the base. The polish rod can then be run through the interior passage of the containment device.

  • Patent number: 10294751
    Abstract: An operating control line is in communication with an operating piston for the safety valve as well as an equalizing piston such that pressure in the operating control line opens the safety valve and holds the equalizer valve closed. A balance chamber receives fluid from an operating piston in the safety valve when the valve opens to displace a floating piston to the open position. Operating control line pressure reduction allows valve closure and opposite floating piston movement to the closed position. If the floating piston is forced by a tubing seal leak against the open position travel stop, pressure in a balance control line against the equalizing valve member moves it from a seat to then equalize pressure on opposed ends of the floating piston allowing a bias force to move the floating piston off the open position stop so the safety valve can open despite the tubing leak.
