    摘要: A method and apparatus for measuring the quality rate of the steam injected into a hydrocarbon formation in a thermal recovery process. The method measures the density and flow rate of the steam downhole using a mechanical/electrical apparatus. The quality of the steam is calculated from the measured density and flow rate. The apparatus comprises an electric motor-generator and turbine wheel combination, the no-load speed of the motor being related to velocity of the steam while the stall torque is related to density of the steam.

    摘要: A method for monitoring fluid properties with a distributed sensor in a wellbore having an inner surface, a top and a bottom comprising causing the distributed sensor to assume a helical shape, pulling the distributed sensor towards the bottom of the wellbore, while retaining the helical shape of the distributed sensor, feeding the distributed sensor into the wellbore so that the distributed sensor is in substantially continuous contact with the inner surface, and allowing the distributed sensor to become at least partially supported by friction at the inner surface.

    摘要: A method and apparatus for manufacturing a continuous metal tube having a plurality of electrical conductors disposed therein, by using a spring member to depress the electrical conductors while a flat metal strip is formed into a tubular member and welded to enclose the electrical conductors. The spring member functions to protect the electrical conductors from heat damage. The welding occurs completely downstream of the spring member in order to avoid excessive heat buildup in the spring member.

    摘要: A method and apparatus for measuring both the quality and flow rate of steam injected into a hydrocarbon formation in a thermal recovery process. The method measures both the quantity of water and the flow rate of the steam. Both measurements can be made at any location in the borehole to determine the quality and quantity of steam injected into a particular formation. The apparatus utilizes a propeller motor/generator combination to determine the vapor flow rate; the drag produced by a network of bristles extending across the borehole determines the vapor flow rate and the quantity of liquid present.
