摘要： A technique facilitates the monitoring of thermodynamic properties of reservoir fluids. The technique utilizes a modular sensor assembly designed to evaluate a sample of a hydrocarbon-containing fluid within a cell body. A variety of sensors may be selectively placed into communication with a sample chamber within the cell body to evaluate the sample at potentially high pressures and temperatures. The sensors may comprise a density-viscosity sensor located in-situ to efficiently measure both the density and viscosity of the sample as a function of pressure and temperature. Other sensors, such as an optic sensor, may also be positioned to measure parameters of the sample while the sample is retained in the sample chamber.

摘要： A device for measuring the fluid density of a two-phase mixture flowing through a tubular member. A rotor assembly is rotatively supported within the tubular member so that it can also move axially within the tubular member. The rotor assembly is balanced against a pair of springs which exert an axial force in the opposite direction upon the rotor assembly. As a two-phase mixture flows through the tubular member it contacts the rotor assembly causing it to rotate about its axis. The rotor assembly is forced against and partially compresses the springs. Means are provided to measure the rotational speed of the rotor assembly and the linear displacement of the rotor assembly. From these measurements the fluid density of the two-phase mixture is calculated.

摘要： A method for fills and/or cleans the measurement cell of a measuring instrument, namely a viscometer and/or density measuring instrument, in particular of a rotational viscometer. A sample is introduced via a sample line into the measurement cell by a pump, and wherein a dynamic viscosity and/or density of the sample is determined in the measurement cell. A funnel-shaped, reversibly openable receiving container, in particular a filling funnel, for the sample, is arranged in the sample line, between the pump and the measurement cell. The receiving container is opened and the sample is introduced into the receiving container. The receiving container is connected to the pump via a pressure line in such a way that, when pressure is applied into the receiving container, a proportion of the sample is dispensed out of the receiving container and introduced into the measurement cell.

摘要： A method and device for estimating a density value ρm indicative of a true density ρ or for estimating a viscosity value ηm indicative of a true viscosity η of a fluid is disclosed. For this, a first resonance frequency fR of a first mechanical oscillator in a reference volume and a second resonance frequency fF of a second mechanical oscillator in contact with the fluid are measured. The estimated value ρm or ηm is then derived using these resonance frequencies fR and fF. During this derivation, at least one fluid-temperature- or fluid-pressure-dependent parameter of the fluid is used. Additionally or alternatively, the first (i.e. reference) mechanical oscillator is arranged in contact with a reference fluid. Thus, fundamental errors in the derivation of the estimated value ρm or ηm are reduced and the estimated value becomes more reliable.
