    摘要: A method and apparatus for providing a local response to a local condition in an oil well are disclosed. A sensor is provided to detect a local condition in a drill string. A controllable element is provided to modulate energy in the drill string. A controller is coupled to the sensor and to the controllable element. The controller receives a signal from the sensor, the signal indicating the presence of said local condition, processes the signal to determine a local energy modulation in the drill string to modify said local condition, and sends a signal to the controllable element to cause the determined local energy modulation.

    摘要: A borehole may be drilled utilizing the bottom hole assembly 10, 50 with a downhole motor 14, which may offset at a selected bend angle. A gauge section 34 is secured to the bit 16 has a uniform diameter bearing surface along an axial length of at least 60% of the bit diameter. The axial spacing between the bend and the bit face is controlled to less than fifteen times the bit diameter. After drilling a section of the well with the BHA according to the present invention, a tubular may be inserted in the well by passing the tubular through an upper tubular, then the inserted tubular expanded while downhole to a diameter substantially equal to the expanded tubular.

    摘要: Fiber optic sensing systems and methods. In a described embodiment, a fiber optic sensing system includes an optical fiber transmitting energy to a chemical vapor deposited diamond material proximate a substance in a well. The diamond material is deposited as a coating on a substrate. The substrate and coating are heated when the energy is transmitted by the optical fiber. This heats the substance in the well, which is detected to determine a property of the substance. In another embodiment, light energy is transmitted through the diamond material.

    摘要: A heated fluid injection string (106) injects heated treatment fluid into a well (102) in a subterranean zone (112) and generates an acoustic signal. An acoustic detector (212) detects the acoustic signal, and an acoustic signal analyzer (214) interprets the detected acoustic signal. In some implementations, the acoustic signal analyzer (214) interprets the detected acoustic signal to determine information about at least one of the heated fluid injection string (106), the well (102), or the subterranean zone (112).
