摘要： A physical attribute migration method for a medium is disclosed. The method comprises forming at least one collection of seismic traces associated with an area of the medium and classified according to a predetermined criterion, and a stack section is produced on the basis of said seismic trace collection using a stacking speed field related to said area. According to the method, (a) the product of a term related to the trace amplitude and a term related to the stacking speeds is determined; (b) the amplitude data and the product are migrated at an initial migration speed to give a migrated amplitude image and a migrated product image, respectively; (c) a ratio is established between the migrated product image data and the migrated amplitude image data to give a migrated position speed; and (d) steps (b) and (c) are iterated in such a way that the migration speed of each iteration is the same as the migrated position speed from the preceding iteration, until the deviation between the migrated position speed of the final iteration (n) and that of the penultimate iteration (n-1) is below a predetermined threshold.

摘要： A flexible pipe including at least one sealing liner (1); an assembly (3) of external reinforcements for withstanding the physical and chemical stress to which the flexible pipe is exposed, which assembly particularly comprises a reinforcement (2) resistant to the pressure of the fluid to be conveyed and consisting of non-contiguous coils (7, 8) wound around said sealing liner (1) in a predetermined direction (e); and an intermediate strip (11) arranged between the pressure-resistant reinforcement (2) and the sealing liner (1), and wound around said sealing liner in a direction parallel or opposite to the winding direction (e) of the coils of the pressure-resistant reinforcement. The intermediate strip (11) has a low modulus of stiffness in said winding direction (e) around the sealing liner, and a high strength and modulus of stiffness in a transverse direction (e') relative to said coil winding direction.

摘要： A multiple-tube flexible pipe (1) including a central flexible member (2) having high tensile and compressive strength, a casing (8) and a plurality of circumferentially arranged tubes (3) wound around the central flexible member to form at least one ply in a ring-shaped space between said central flexible member (2) and said casing (8). At least one of said circumferentially arranged tubes (3) has low compressive and/or tensile strength. The flexible pipe further comprises at least one flexible compressive force transmitting member (5) arranged in said ring-shaped space and adjacent to said tube (3, 4) having low compressive and/or tensile strength.

摘要： An automatic seismic pattern recognition method is characterised in that it includes determining a given number of seismic patterns to be recognised; providing a set of seismic trace portions for said region; defining a pattern recognition parameter common to all the trace portions, and determining the value of said parameter for each of the trace portions of the set; selecting trace portions among said set; selecting a one-dimensional neural network containing as many cells as there are patterns to be recognised, each cell being assigned a value of the recognition parameter; submitting the neural network to a learning process with the selected trace portions, so that at the end of said process, each cell matches a pattern to be recognised, and that said patterns are progressively ordered; presenting each trace portion of said set to be processed to the classified and ordered neural network; and attributing to each trace portion presented to the network the number of the cell closest to it. The invention is particularly useful for recognising seismic patterns between two horizons defined by plotting a seismic section.

摘要： A method for representing the path of one or more boreholes in a spatial and temporal domain, characterised in that it includes the steps of: (a) developing a velocity-depth model (4) keyed with said borehole (1), geologically representative of said zone and including a representation of said borehole path (5); (b) selecting one or more points (A) on or adjacent to said path, said point (A) being defined by its spatial co-ordinates and by at least a pair of dip/azimuth data; and (c) at least modelling in a synthetic sum domain (9) the image (a) of the selected point (A), wherein said image (a) is defined by the spatial and temporal co-ordinates and by a dip/time vector, and is obtained by projecting a zero offset ray in the velocity/depth model (4).

摘要： A method for modelling kinematic seismic data processed with at least one motion operator, wherein the mid-point (N1) of a transmitter (S)/receiver (R) system is determined, a ray tracing for the system is established relative to a given reflector, the ray parameters are processed using a motion operator to provide a first arrival point (N'1) located on the model, the position deviation (ΔE) between the reference points (N) and the point (N'1) is determined and compared with a predetermined deviation (Δe), and an iteration is performed on each new arrival point (N'i) until the deviation (ΔE) is the same as or smaller than the predetermined deviation (Δe). The method is particularly useful in tomography.
