摘要： A bottomhole assembly (BHA) coupled to a drill string includes one or more controllers, and a hole enlargement device that selectively enlarges the diameter of the wellbore formed by the drill bit. The hole enlargement device includes an actuation unit that may move extendable cutting elements o the hole enlargement device between a radially extended position and a radially retracted position. The actuation unit may be responsive to a signal that is transmitted from a downhole and/or a surface location. The hole enlargement device may also include one or more position sensors that transmit a position signal indicative of a radial position of the cutting elements. In an illustrative operating mode, one or more operating parameters of the hole enlargement device may be adjusted based on one or more measured parameters. This adjustment may be done in a closed-loop or automated fashion and/or by human personnel.

摘要： A bottom hole assembly (BHA) coupled to a drill string includes a steering device, one or more controllers, and a hole enlargement device that selectively enlarges the diameter of the wellbore formed by the drill bit. In an automated drilling mode, the controller controls drilling direction by issuing instructions to the steering device. In one arrangement, the hole enlargement device is integrated into a shaft of a drilling motor that rotates the drill bit. The hole enlargement device includes an actuation unit and an electronics package that cooperate to translate extendable cutting elements between a radially extended position and a radially retracted position. The electronics package may be responsive to a signal that is transmitted from a downhole and/or a surface location. The hole enlargement device may also include one or more position sensors that transmit a position signal indicative of a radial position of the cutting elements.

摘要： The present invention provides a method and system in which signals from the surface are sent by changing flow rate of the drilling fluid supplied to the drill string during drilling of a wellbore. The signals are sent based on a fixed or dynamic time period schemes so that the sent signals cross a threshold value in a known manner. A detector measures the changes in the flow rate. A controller downhole determines the number of times a downhole parameter, such as voltage, relating to the changes in the flow rate crosses a predefined threshold value. Based on the number of the crossings and the timing of such crossings, signals are assigned to commands. The controller controls or operates a steering device based on the commands.

摘要： The present invention provides a method and system in which signals from the surface are sent by changing flow rate of the drilling fluid supplied to the drill string during drilling of a wellbore. The signals are sent based on a fixed or dynamic time period schemes so that the sent signals cross a dynamic threshold value in a known manner. A controller downhole sets the dynamic threshold and determines the number of times a parameter, such as voltage, relating to the changes in the flow rate crosses the set dynamic threshold. Based on the number of the number of crossings and/or the number of crossings and the timing of such crossings, the controller ascertains the signal sent from the surface for use downhole.
