摘要： Embodiments of a method and apparatus for locating lateral wellbores ( 106) extending from a main wellbore (102) includes a caliper sensing tool (104) having spring actuated calipers ( 126) extending radially therefrom. Each of the calipers (126) is connected to a sensor ( 142), such as a linear variable displacement sensor, that is used to calculate the radial extension distance of the respective caliper (12.6). When the tool (104) is inserted through a wellbore (102) and moves past a iaterai wellbore opening, the calipers (126) extend into the lateral wellbore opening. The extension, as well as contact with the surfaces of the lateral wellbore (106), are used to determine the wellbore depth location and azimuthal direction of the lateral wellbore (106). A deflectable steering arm (122) is operable to be selectively steered into the lateral opening to facilitate access to the lateral wellbore (106) for logging or intervention purposes.

摘要： Multiple sensors on a drill string can be utilized to perform equivalent circulation density (ECD) analysis. By utilizing multiple ones of the sensors, the pressure drop in each section of the wellbore can be classified. Additionally, the inclusion of multiple sensors in the drill string allows a wellbore to be sectioned into intervals bounded by any two sensors. Pressure events occurring in a single section of the wellbore bounded by any two sensors can be isolated and analyzed. The isolation can be achieved by subtracting the pressure measured on the shallower sensor from that measured on the deeper sensor.

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： Aspects of this invention include a downhole tool and method for making a physical caliper measurement of a subterranean borehole. The tool is configured to make the physical borehole caliper measurement only when the measured pressure in each of three or more outwardly extendable blades is greater than a predetermined threshold pressure. Blade positions are measured and the borehole caliper calculated only when the pressure in each of the blades exceeds the threshold. Exemplary embodiments of the invention enable physical caliper measurements to be made with increased accuracy with each of the blades making firm contact with the borehole wall. Methods in accordance with the invention are especially well suited for use in directional drilling applications in that they tend to enable accurate caliper measurements to be made without repositioning the steering tool in the borehole.
