摘要： A distributed acoustic sensor, comprises a housing having a longitudinal bore therethrough, an optical fiber supported in the bore; and an inertial member supported within the bore, wherein the fiber is mechanically coupled to the inertial member. The inertial member may include a weight and may provides isotropic stiffness such that it deforms more readily in a first direction normal to the bore than it does in a second direction that is normal to both the bore and the first direction. The sensor may include a plurality of axially-spaced centralizers in the bore, and at least one of the inertial member and the centralizers may comprise swellable material.

摘要： A system for monitoring subsidence and/or rising of a waterbottom (3), such as an ultradeep oceanfloor, has a string of pressure sensors (2) along the length of the interior (13) of a sealed pressure resistant protective tube (1) that rests on the waterbottom (3) and is filled with a low pressure liquid, such as water, so that any subsidence and/or rising of the waterbottom (3) can be deduced from subsidence and/or rising of a section of the tube (1) and associated variation of the fluid pressures measured by the pressure sensors due to variation of the hydrostatic fluid pressure of the low pressure liquid in the interior (13) of the tube (1). The tube (1) is equipped with a series of valves (10) which divide its interior (13) into a series of sealed segments during descent to protect the pressure sensors (2) against hydrostatic pressure of the liquid within the tube(l) during installation. The use of a pressure resistant tube (1) filled with a low pressure liquid allows the use of sensitive pressure sensors (2) which are able to monitor pressure variations of -0.001 Bar associated with a waterbottom subsidence of ~1 cm, at a waterdepth of >km where the ambient water pressure may be >100 Bar.

摘要： A U-shaped fiber optical cable assembly (11, 21) is arranged in a heated well (1) such that a nose section (13, 23) comprising the bent U-shaped cable section (11C, 21C) is located near the toe (1 A) of the well where the ambient well temperature is lower than the temperature of an intermediate section of the well which is heated by steam injection, electrical heating and/or influx of heated hydrocarbon fluids from a heated section of the surrounding formation to a temperature above 200 degrees Celsius, thereby inhibiting the risk of hydrogen darkening of the bent U-shaped cable section. It is preferred to make the nose section of a glass solder, to arrange the U-shaped fiber optical cable assembly in an aluminium guide tube (22) sealed at its lower end with end cap (31), and to use a heat resistant fiber optical cable to further inhibit the risk of hydrogen darkening of the assembly.

摘要： The sensitivity of a fiber optical sensing assembly (2) with Fibre Bragg Gratings ( FBGs) (3, 4) to temperature variations in the associated light source (6) is reduced by using an interrogation system (1) with first and second sensors ( 12&15) that are connected to the sensing assembly (2) and to a reference element ( 14 ) to generate a measurement signal (M1, M2) and a reference signal, and a signal processing device (13), which identifies peaks (R1, R2) of the reference signal, compares a pattern of the identified peaks (R1, R2) with a known pattern of the reference spectrum to determine an order of wavelengths in the reference signal, and calculates for at least one peak an associated wavelength using the order of wavelengths in the reference signal, thereby avoiding that a different order of the peaks (R1, R2) in the reference signal, for instance due to temperature variations at the light source (6), results in false calculation of a wavelength in the measurement signal (M1, M2).
