摘要： Apparatus and methods regarding a first processing system operable to receive a job plan developed by a second processing system, and implement the job plan, including generating commands for an equipment controller based on the job plan. The first processing system is operable to transmit, through a network, the commands to the controller for execution by the controller. The first processing system is operable to iteratively (i) monitor, through the network, current conditions of the well construction system during execution of commands by the controller; (ii) update the implementation of the job plan, including generating updated commands for the controller based on the job plan and the current well construction system conditions when the current well construction system conditions indicate a deviation from the implementation; and (iii) transmit, through the network, the updated commands to the controller for execution by the controller.

摘要： A technique employs the use of oscillations downhole to facilitate a desired functionality of a downhole tool. According to this technique, a tool is initially conveyed downhole and operated to perform a function that relates to a downhole application. The operational efficiency of the tool is improved by creating oscillating forces which vibrate the tool to achieve a desired result, e.g. freeing the tool from a stuck position.

摘要： Methods and apparatus for controlling drill string rotation. The apparatus may be a control system for controlling a driver operable to rotate a drill string to form a wellbore extending into a subterranean formation. The control system may include a first controller operable to control rotation of the driver and a second controller communicatively connected with the first controller. During the drilling operations the first and/or second controller may be operable to generate a rotational speed command based on status information indicative of operational status of the drill string, and thereby cause the driver to rotate the drill string based on the rotational speed command.

摘要： A system may include a control system coupled to various network elements that define a drilling management network. The control system may include a programmable logic controller (PLC) that performs a drilling operation. The system may further include a virtualization services manager coupled to the control system and the network elements. The virtualization services manager may implement a virtualization service on the drilling management network that controls the drilling operation. The system may further include a virtual connection controller coupled to the network elements. The virtual connection controller may establish a virtual connection between the control system and a user network.

摘要： A method includes creating a digital description of the well construction system, wherein the digital description of the well construction system describes the locational relationship of components in the well construction system, collecting multiple types of data from a well construction system, and tagging the collected data with an identification indicating at least one of a location of a source of collected data and a component in the well construction system from which the data is collected. The multiple types of data include sensor data collected from one or more sensors disposed along the well construction system and operational state data indicating an on/off status of one or more components in the well construction system.

摘要： A method for steering a downhole tool in a wellbore includes measuring a tool face when the drill bit is off-bottom, measuring an angular position of a drill string when the drill bit is off-bottom, and measuring a torque on the drill string when the drill bit is off-bottom. The method also includes measuring the tool face when the drill bit is on-bottom and measuring the torque on the drill string when the drill bit is on-bottom. The method also includes determining a transfer function comprising the angular position of the quill, the difference between the tool face when the drill bit is on-bottom and off-bottom, and the difference between the torque when the drill bit is on-bottom and off-bottom. The angular position of the drill string is varied at the surface, based upon the transfer function, to reduce an angle between the tool face when the drill bit is on-bottom and a target tool face.

摘要： Systems and methods for tracking depth of a drill string. The method includes determining a measured elevation difference between a first position of a sensor and a second position of the sensor, based on measurements taken by an elevation measurement device, determining a calibration elevation difference between the first and second positions based on measurements taken by the sensor using markers positioned at predetermined elevations, and calibrating the elevation measurement device based at least partially on a relationship between the measured elevation difference and the calibration elevation difference.
