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 flow rate device for measuring the flow rate of a fluid flowing through a wellbore is disclosed. The flow rate device includes a differential pressure conduit, a flow restrictor insert and a differential pressure measurement device. The differential pressure conduit is locatable in the wellbore, defines an internal bore, and is adapted to include a restriction having a cross-sectional area to increase the velocity of fluid flowing through the differential pressure conduit to create a differential pressure. The differential pressure conduit defining first and second pressure measuring stations axially spaced along the differential pressure conduit. The flow restrictor insert is located in the restriction to reduce the cross-sectional area of the restriction. The flow restrictor insert defines an internal bore having a cross-sectional area less than the cross-sectional area of the restriction. The flow restrictor insert also has a pressure measuring port aligned with the second pressure measuring station. The differential pressure measurement device has at least one pressure sensor for detecting the pressure at the first pressure station, and for detecting the pressure at the second pressure station to generate a signal indicative of the flow rate of the fluid.

摘要： The invention relates to a method of measuring pressure in which an evacuated capsule (1) containing a resonant element (5) is placed in the fluid whose pressure is to be measured, a vibration characteristic of the element is measured, and the pressure is deduced from said characteristic. A resonant element is used which, during measurement, is to be found in a stress state that is close to buckling. For this purpose, it is possible to use heater means for heating the element and servo-controlled so as to keep the frequency of vibration thereof constant. The resonant element can be made of silicon. The invention is particularly applicable to oil wells.

摘要： To discriminate optically between the various phases in a three-phase fluid, a light beam (F) of non-zero divergence is injected into a detector block (10) made of a material whose refractive index is greater than the refractive indices of all three phases of the fluid. The block (10) has a sensitive zone (18) and a total reflection zone (20) such that incident rays (Ri) parallel to the axis (12) of the block strike the sensitive zone (17) at an angle of incidence (&thetas;i) and are returned parallel to the axis (12) by the total reflection zone (20). The angle of incidence (&thetas;i) is such that a first phase gives rise to almost total reflection, a second phase gives rise to almost total transmission, and a third phase gives rise to partial transmission and partial reflection.
