摘要： Method and apparatus are disclosed for accurately determining position from GPS satellites (12,13,14) and received on a ship (10) using the following observable signals: C/A code group delay observable τ; 308 f o implicit carrier phase observable ϕ; L1 band implicit f o carrier residual phase observable ψ L1; and L2 band implicit f o carrier residual phase observable ψ L 2 . A precise measurement of the group-phase delay range to each satellite is made based upon the L1 center frequency carrier phase. A correction for ionospheric effects is determined by simultaneous observation of the group delays of the wide bandwidth P code modulations in both the L1 and L2 bands. These group delays are determined by measuring the phases of carrier waves implicit in the spread-spectrum signals received in both bands. These carriers are reconstructed from both the L and L2 band signals from each satellite without using knowledge of the P code. The unknown biases in the L1 center frequency carrier phase range measurements are determined from simultaneous, pseudorange measurements, with time averaging. The instantaneous position of the ship (10) may then be determined from the ranges so determined, with both the bias and the ionospheric effects having been eliminated.

摘要： A hydrophone streamer (12) that includes several arrays (20) of optical fiber pressure sensors. Each array (20) consists of at least three sensors (30, 32, 34) symmetrically disposed around the inside of the streamer skin (26) to form a vertically-disposed array. Each sensor modulates a coherent light beam (47) in accordance with the instantaneous ambient water pressure. The output signals of the sensors include an AC component due to seismic waves and a DC component due to hydrostatic pressure difference between the sensors of an array. Means (22) are provided to resolve the AC (62, 66) and DC (56) components to determine the arrival direction of the received seismic waves.

摘要： A method for obtaining far-field signatures of marine source arrays (12) by the downward continuation of near-field data recorded along a short signature streamer (14) of closely spaced hydrophones (28, 30, 32), located beneath the array (12). This method has several advantages over conventional far-field signature measurement techniques. The technique can be used in water depths as shallow as 50 meters, it does not require any precise knowledge of the array (12) geometry or of the location of the recording sensors (28, 30, 32), and it may be used on a shot-by-shot basis to obtain signatures for use in a shot-by-shot signature deconvolution.

摘要： A system for creating seismic exploration shot-holes. A slender shaft is formed into the soil and the lower end of the shaft is underreamed to generate a cavity. An explosive material is positioned within the cavity and is detonated to generate seismic source energy. The slender shot-hole reduces the drilling material excavated and substantially reduces the seismic source energy dissipated upwardly through the shot-hole. The explosive filled cavity can be spherical, conical, hemispherical, or other shapes to maximize the transfer of seismic source energy from the explosive material to the subsurface geologic formations. The invention significantly expedites shot-hole drilling and provides an improved system for coupling the explosive material energy to the geologic formations.

摘要： An apparatus for generating signals and energy for transmission to a large mass (17). The apparatus incorporates a pulsed generator (10) such as a compensated pulsed alternator for storing and for discharging large amounts of energy in a controlled manner for transmission through a vibrator or similar electromechanical device. In the field of seismic exploration, the apparatus discharges seismic source energy into a land mass or water to generate seismic waves which are reflected from the interface between subsurface geologic formations. The pulsed generator (10) permits the seismic source energy to be discharged in a controlled manner to shape the energy signal, and permits large quantities of energy to be discharged to increase the penetration depth and strength of the reflected signals.

摘要： An apparatus and method for selectively locking the orientation of seismic data sensor capable of detecting data regarding a seismic event. A gimbal orients the sensor into a selected vertical orientation, and a switch operates a clutch to lock the sensor from further movement. A controller can identify a time interval correlating with a seismic event, and the controller operates the switch to lock the sensor before the seismic event begins. After the completion of the seismic event, the switch unlocks the sensor so that the gimbal can permit reorientation of the sensor. The locking mechanism eliminates noise associated with moving gimbal components and is suitable for land based and marine seismic operations.
