Instrumented drill string element |
摘要 |
A drill string element including an elongate tubular body delimiting an interior surface longitudinally including at least one portion of revolution and including a first hole provided in the elongate tubular body. That first hole includes a first end opening at the portion of revolution, and in a vicinity of the first end a longitudinal axis intersecting the interior surface at an intersection location. The longitudinal axis, in projection into a first plane passing through the central axis of the portion of revolution and containing the intersection location, forms a first angle of a value that is not zero and in projection into a second plane tangential to the interior surface at the intersection location forms a second angle of a value that is not zero. |

1. A drill string element comprising:
an elongate tubular body delimiting an interior surface longitudinally including at least one portion of revolution and a first hole provided in the elongate tubular body, the first hole including a first end opening at the portion of revolution, the first hole including in a vicinity of the first end a longitudinal axis intersecting the interior surface at an intersection location, wherein the longitudinal axis, in projection into a first plane passing through the central axis of the portion of revolution and containing the intersection location, forms a first angle of a value that is not zero and in projection into a second plane tangential to an interior surface at the intersection location forms a second angle of a value that is not zero, wherein the second plane is perpendicular to the first plane. |
