摘要： A method, system and drilling apparatus for directional drilling are disclosed. A drill bit is located at a downhole end of a drill string in a borehole. A length of the borehole between a surface location and the drill bit at the downhole end of a drill string is determined and an azimuth angle and inclination of the drill bit is obtained. The length of the borehole may be determined by recording an arrival time at a downhole location of an acoustic pulse travelling from a surface location to the downhole location and determines the travel time and borehole length therefrom. A downhole processor determines a position and orientation of the drill bit from the determined length, azimuth angle and inclination and alters a steering parameter of the drill bit using the determined position and orientation of the drill bit to obtain a selected trajectory for drilling the borehole.

摘要： Systems and sensor elements for indirect monitoring of cumulative damage to downhole components are described. The systems include a sensor body defining an internal cavity with at least one electrical wear element located within the sensor body. A portion of the at least one electrical wear element electrically extends from the internal cavity, through the sensor body, and to an exterior of the sensor body. An abrasive substance is located within the internal cavity, the abrasive substance being moveable within the internal cavity to contact and erode material of the at least one electrical wear element such that erosion of the at least one electrical wear element causes a resistance of the at least one electrical wear element to increase.

摘要： A method for performing a formation fluid test in a borehole penetrating a subsurface formation includes disposing a fluid tester in the borehole, extracting a sample of fluid from the subsurface formation using the fluid tester, and analyzing the sample using the fluid tester to provide test data for a process used to analyze the sample. The method also includes fitting an equation to the test data and calculating a ratio of a first derivative of the equation to a second derivative of the equation. The method further includes continuing to extract the sample from the subsurface formation in response to the ratio indicating a clean sample will be forthcoming and terminating the extracting of the sample from the subsurface formation in response to the ratio indicating a clean sample will not be forthcoming.

摘要： An apparatus for estimating an ambient environment at which inorganic scale will form in a downhole fluid includes a stress chamber disposed in a borehole in a production zone at a location within a specified range of maximum pressure and configured to receive a sample of the fluid from the production zone and to apply an ambient condition to the sample that causes the formation of inorganic scale. An inorganic scale sensor is configured to sense formation of inorganic scale within the chamber and an ambient environment sensor is configured to sense an ambient environment within the chamber at which the formation of inorganic scale occurs. The apparatus further includes a processor configured to receive measurement data from the inorganic scale sensor and the ambient environment sensor and to identify the ambient environment at which the formation of inorganic scale occurs.

摘要： An apparatus for estimating an ambient environment at which organic scale will form in a downhole fluid includes a stress chamber disposed in a borehole in a production zone at a location of maximum pressure and configured to receive a sample of the fluid from the production zone and to apply an ambient condition to the sample that causes the formation of organic scale. A sensor is configured to sense formation of organic scale within the chamber and an ambient environment sensor is configured to sense an ambient environment within the chamber at which the formation of organic scale occurs. The apparatus further includes a processor configured to receive measurement data from the organic scaling sensor and the ambient environment sensor and to identify the ambient environment at which the formation of organic scale occurs using the organic scaling sensor measurement data and ambient environment sensor measurement data.
