摘要： A method for controlling the electrical power delivered to a downhole system. The downhole system may include a power supply, a downhole tool, and a wire or cable connecting the downhole tool to the power supply. A resistive load, such as a motor, is included with the downhole tool. The power supplied to the downhole tool is dynamically adjustable to match the resistive load voltage and power rating. Dynamically adjusting power is accomplished by varying voltage from the power supply, varying the resistive load requirements, or a combination of both.

摘要： The casing cutter disclosed herein is useful for severing downhole tubulars and comprises a body, a cutting head, cutting blades, and actuators for operating the cutting head and cutting blades. Cutting is accomplished by rotatingly actuating the cutting head with an associated motor, and then radially extending the cutting blades away from the cutting head. In one embodiment, the cutting head includes a cutting member that pivotally extends from the cutting head upon rotation of the cutting head. In another embodiment, cutting members extend from the cutting head due to centrifugal forces associated with rotating the cutting head.

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.

摘要： A method of performing a formation rate analysis from pressure and formation flow rate data. Pressure and flow rate data are measured as fluid is withdrawn from a formation. Variable system volume is accounted for. The pressure and flow rate data are correlated using a multiple linear regression technique. Time derivative terms related to pressure and flow rate are smoothed using a summation technique, thereby providing better correlations than using the time derivatives directly. Formation parameters comprising formation permeability, formation pressure, and fluid compressibility may be determined from the correlation.
