摘要： An improved hydrophone is presented that has extremely low acceleration sensitivity, hermetic sealing, and is self-shielded. The hydrophone can also contain an integral amplifier and pressure/depth limiting switch. The hydrophone is also designed such that it can use a single standard piezoelectric sensing element in many hydrophone designs that have different acoustic pressure sensitivities but the same capacitance. Lastly, the sensor is also designed to he low cost in high volumes using standard accelerometer manufacturing techniques. A hydrophone is also designed such that it can use a single standard piezoelectric sensing element that can be incorporated into several hydrophone configurations with varying acoustic pressure sensitivities. The sensor is also designed to be low cost in high volumes.

摘要： The invention consists of an optical hydrophone, an optical fiber element forming a laser cavity, housed in a mechanical structure which comprises an open cylindrical rigid body, defining the cavity enclosing a fluid and in which the optical fiber element is housed, and closed at its ends by two end caps which keep the optical fiber element permanently under tension, in a longitudinal rectilinear position inside the cavity. The end caps are configured in such a way that when the exterior pressure varies, they undergo a deformation giving rise to a variation in the length of the optical fiber element and that when the temperature varies, they undergo a deformation giving rise to a variation in the length of the optical fiber element which compensates for that induced on this element by the temperature variation. The mechanical structure furthermore exhibits one or more orifices allowing equilibration of the static pressures.

摘要： This disclosure is related to hydrophones, for example hydrophones that may be used in marine seismic surveying, permanent reservoir monitoring, downhole acoustic monitoring in a wellbore, and/or various other applications. Some embodiments of a hydrophone according to this disclosure are constructed such that a longitudinal stiffness of the hydrophone is greater than a circumferential stiffness of the hydrophone. In some embodiments, however, the longitudinal stiffness may be somewhat less than the circumferential stiffness. For example, the longitudinal stiffness may be greater than one half the circumferential stiffness in some cases.

摘要： An apparatus for sensing a parameter beneath a surface of the earth includes an optical fiber disposed beneath a surface of the earth and comprising at least one fiber Bragg grating sensor configured to sense the parameter and a wide-band light source disposed beneath the surface of the earth and configured to emit light in a wide band of wavelengths to illuminate the at least one fiber Bragg grating. An optical interrogator is disposed beneath the surface of the earth and configured to receive light reflected by the at least one fiber Bragg grating sensor and to transform a shift in wavelength of the reflected light into a variation of light intensity. A photo-sensor is configured to measure intensity of light received from the optical interrogator. Electronics are coupled to the photo-sensor and configured to measure a voltage representing the light intensity at the photo-sensor to sense the parameter.

摘要： According to one example, a floodable sensor station is coupled to an optical cable. The optical cable may be floodable. The floodable sensor station may connect floodable optical cables as part of a permanent reservoir monitoring system. The floodable optical cable may house a plurality of floodable optical fiber conduits. The floodable sensor station may be pressure-balanced with its surrounding environment in high-pressure marine depths of 1500 meters or more.

摘要： Method, source array and source element that generate seismic waves. The source element includes an enclosure having an opening covered by a piston; a local supply accumulator fluidly communicating with an interior of the enclosure, a pressure of the fluid inside the local supply accumulator being larger than a pressure of the fluid inside the enclosure; a local supply valve located between the local supply accumulator and the enclosure and configured to control a flow of the fluid from the local supply accumulator to the interior of the enclosure; and a controller configured to control the local supply valve such that the pressure inside the enclosure does not fall below a first preset value based upon an ambient pressure of the enclosure while seismic waves are generated.

摘要： Computing device, software and method for balancing forces acting on a piston of a marine vibrator towed in a body of water. The method includes estimating with a management system located on a vessel or a controller located on a marine vibrator, a transient pressure disturbance in the body of water; computing, at the controller, a force correction for the piston of the marine vibrator, based on the transient pressure disturbance; and instructing an actuation system of the marine vibrator to apply the force correction to the piston in anticipation of an arrival of the transient pressure disturbance.
