摘要： Systems and methods are described for monitoring displacement on structural elements of subsea systems such as on components of a subsea pipeline network used to transport production fluid from a subsurface wellhead to surface facilities. The described techniques sense changes in displacement using a sensing blade, for example made of crystalline material such as sapphire, that is anchored to the structural element such that it is approximately perpendicular to the direction of sensed displacement. Displacement is sensed as bending of the sensing blade using one or more instruments fabricated on the blade. Robustness of design is in part provided by additional flexible non-sensing blades mounted in parallel to the sensing blade.

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： A pressure transducer (sensor) (20) includes a deformable diaphragm (22) which closes off a fluid passage (18) in a leaktight manner. In order to protect the diaphragm (22) against shocks, the passage (18), comprises a constriction (44) whose dimensions are defined so as to limit the pressure peak applied to the diaphragm to a cutoff value which can be withstood by this diaphragm. The constriction (44) may be formed in a removable capillary tube (42) or may be in the form of grooves made in a silicon wafer integrated with the active part of the sensor.

摘要： Electrical circuit such as a Wheatstone bridge composed of resistors (7 to 10) connected by track widenings (11 to 14). The widenings connected to a measuring apparatus (V) of high impedance comprising segments with adjustable resistance (17, 18). Since the widenings (12 and 14) widen essentially towards these segments, no substantial current passes through the portions of strands which are cut, one of whose ends has undergone a change in its chemical composition which could otherwise disturb the stability of the circuit as a function of time. Very-high-precision measurements are therefore possible. … One application relates to pressure sensors subjected to strong variations in temperature and to very long-term measurements. … …

摘要： Un instrumento (10) de adquisición y análisis de muestras de formación incluye una broca anular (12) configurada para acoplarse a un extremo de una sarta de perforación (20). La broca define un pasaje (12D) que se extiende desde una cara de corte de la misma hasta una superficie exterior en una posición espaciada longitudinalmente de la cara de corte. El instrumento incluye por lo menos un sensor (44, 46, 48) configurado para medir un parámetro seleccionado de una muestra de formación subsuperficial empujada en el pasaje (12D) por la acción de la cara de corte contra las formaciones subsuperficiales. Muestras de las formaciones subsuperficiales son eyectadas desde el extremo de superficie exterior del pasaje por las muestras que ingresan en el extremo de cara de corte.
