    摘要： A downhole optical apparatus includes an LED source, reflectance and fluorescence detectors, a plurality of fibers, a dichroic mirror (DM), a beam splitter/coupler, a probe, a short-pass filter (SP), a dichroic long-pass filter (LP), and a lens. Source light filtered by the SP is fed to the DM which deflects light of desired wavelengths only. The deflected light is focused by the lens onto a fiber and is ultimately injected into an oil flow by the probe. Light reflected by oil or fluorescing therefrom is received by the probe, and split by the splitter. A small portion is received by the reflectance detector. A large portion is received by the lens and directed to the DM which deflects reflected light and passes light at longer fluorescing wavelengths. Passed light is further filtered by the DM and LP to eliminate remnants of the reflected light, and provided to the fluorescence detector.

    摘要： An apparatus includes a circuit to receive power and data over a communication medium, where the circuit is to separate the power and the data. An electronic switch couples the power output by the circuit to a downhole electrical component for use in a well. According to other implementations, an electro-hydraulic actuator includes an outer housing defining a first hydraulic chamber and a second hydraulic chamber, where a seal for one of the hydraulic chambers is achieved without use of an elastomeric seal.

    摘要： The invention concerns a method for calculating the relative volumetric flow-rates of at least one of the phases of a multiphase effluent flowing in a well. Firstly, the local volumetric fractions and/or velocities of the phases across a section of the wall at a certain depth is acquired. Then, the local volumetric fraction and/or velocity measurements is/are corrected in order to make them consistent with each other and/or with the effluent flow conditions. Subsequently, selection of a suitable flow model mathematically representing the effluent flow is selected. Then, The local volumetric fraction measurements and/or the local velocity measurements are interpolated by the selected flow model in order to obtain a volumetric fraction profile and/or a velocity profile for at least one phase of the effluent across the section of the well at the depth. Finally, the relative volumetric flow-rates of the at least one phase are calculated by integration of the volumetric fraction and/or velocity profiles over the section of the well at the depth.
