摘要： This invention relates to methods and apparatus for analyzing a multi-phase fluid flowing along a hydrocarbon well in order to determine, at each depth, the average static proportion of one of the phases by means of a local measurement. At each depth the local static proportion of the phase under investigation is determined at a point in the flow, which point is situated on a circle having a radius r in the transverse -section corresponding to the depth, where the radius r is substantially equal to 0.7 R, and R is equal to radius of the well. The local static proportion at this point is related to the average static proportion by a determined relationship.

摘要： Improved equipment and methods for determining the waiting-on-cement time after a cementing operation involve an optic-fiber coil that immersed in the cement slurry downhole. The intensity of a reflected light signal from the coil is monitored versus time. Attenuation of the reflected-light intensity corresponds to the development of gel strength, allowing operators to unambiguously determine when well-bore operations may recommence after a cement job. The optic-fibre coil is wound around a spool such that there is at least one coil crossing on the spool.

摘要： Fiber-optic cable systems are useful for locating a cementing apparatus in the wellbore, for example a cement plug. A reel of fiber-optic cable is attached to the cementing apparatus. At the surface the cable is attached to a stationary position where it is connected to a light transmitter/receive device. As the cementing apparatus travels down the cased wellbore, the cable unwinds, thereby changing the nature of the reflected light signal and allowing one to deduce the position of the cement plug within the well.
