摘要： A method and device for processing a seismic survey data set including: an actual source location, an actual receiver location, and an actual reflection event location is provided. The actual source location and actual receiver location are over a first layer having a first layer velocity and a first layer ray parameter, and over a second layer having a second layer velocity different from the first layer velocity and a second layer ray parameter different from the first layer ray parameter. The actual reflection event location is located below the first layer. The method comprises: providing the first layer velocity; providing the second layer velocity; providing the first layer ray parameter; providing the second layer ray parameter; determining a correction factor for the position of a ray path end dependant upon the first and second layer velocities and the first and second layer ray parameters; and applying the correction factor to the ray path end, wherein a ray path-corrected ray path end is provided. The ray path end comprises a member of the group consisting of: the actual source location, the actual receiver location, and the actual reflection event location. The ray path corrected ray path end comprises a member of the group consisting of: the ray path corrected source location, the ray path corrected receiver location, and the ray path corrected reflection event location.

摘要： Drive assembly for acoustic sources having sound emitting surfaces adapted to be excited into vibration movements, in particular for use in seismic explorations. The assembly comprises an electric rotational motor (17) with an associated axle which comprises an axle part (18) the outer cross-sectional contour of which at least partially in the axial extension of the axle part is non-circular, but preferably smoothly rounded. Further the assembly comprises a number of push rods (21, 22) being arranged radially in relation to the axle (18) and adapted to preferably indirectly at their radially inner ends (23, 24) to be influenced by the non-circular axle part (18) during rotation of the axle, whereas the radially outer ends of the push rods (21, 22) are adapted to excite said sound emitting surfaces (1) into vibrational movement.

摘要： Acoustic transmitter in particular for use in offshore seismic explorations, having sound-emitting surfaces (1, 2) being adapted to be subjected to vibrational movement by means of a drive unit (21) through at least one push element (22A, 22B) and two plate-like end pieces (3, 4) which are connected to the sound-emitting surfaces. The sound-emitting surfaces are formed by two curved plate members (1, 2) being of comparable width and heigth dimensions. The end pieces (3, 4) have a generally rectangular shape with a first pair of opposing side edges connected (5, 6, 7, 8) to end portions of the plate members (1, 2). Another pair of side edges on each end piece (3, 4) as well as side edges of the plate members engage two side plates (9, 10) which at either side closes the acoustic transmitter, preferably in a tightly enclosing manner.

摘要： Flextensional acoustic source with sound-emitting surfaces (1, 2, 3, 4) adapted to be excited into vibrational movement, and for use in seismic exploration at sea. The source comprises a drive unit (21) being through the intermediary of at least one push element (22A, 22B) adapted to impose vibrational movement to the sound-emitting surfaces. Between at least one push element (22A, 22B) and the associated sound-emitting surface(s) (1, 2, 3, 4) there is provided a non-linear spring element (27, 28) the spring constant of which is controllable. Two oppositely acting push elements (22A, 22B) are arranged in axial alignment and preferably centrally in the source, and in addition thereto there are provided at least two tension elements (39, 40) with associated controllable, non-linear spring elements (35, 36, 37, 38) and being coupled to the sound-emitting surfaces (1, 2, 3, 4).
