摘要： A method of processing seismic data, said seismic data having been obtained by: performing a plurality of sweeps, wherein each sweep comprises generating seismic signals in the earth using a plurality of vibrators by applying a pilot sweep wave-form to each vibrator, each pilot sweep being a waveform of changing frequency; measuring the force applied to the earth by each vibrator to determine a measured force waveform; and measuring the seismic signals at one or more locations remote from the vibrators; said method comprising: filtering the measured force waveform to remove harmonics of the pilot sweep and thus determining a filtered force waveform; generating an inversion operator from the filtered force waveform for each vibrator; and applying said inversion operator to the measured seismic signals to determine the contribution of each vibrator to the seismic signals.

摘要： A process for separating waves in borehole seismics for walkaway-type acquisitions. Waves are generated in a medium from several positions of a source. The waves are received at at least three sensors along axes V, H.sub.1, H.sub.2. Collections of C traces are formed with a common source. On the basis of the trace collection, collections of residual C traces and C signals, a pivot trace is selected from the collection of residual C traces. A straight line of variable slope p is plotted at each sampled point of the pivot trace. The amplitudes of the seismic events located at the intersections of the traces with the straight line are summed along the straight line. The amplitude sums are then transferred to a domain (.tau., p). A synthetic seismogram is made from the domain (.tau., p) and iterations are performed until the synthetic seismogram is acceptable in terms of the data of the collection of residual C traces.

摘要： A method for generating, recording and pre-processing high fidelity vibratory seismic data in a system that uses a plurality of vibratory sources includes the steps of measuring the motion of each of the vibrators, determining a ratio by dividing the vibratory seismic data by the measured motion of the vibrator to remove the unknown applied force leaving the earth reflectivity times a time derivative divided by a minimum phase function, minimum phase band pass filtering the resulting ratio and performing minimum phase deconvolution to remove the time derivative divided by the transfer function of minimum phase. The method may also include the steps of shot ensemble deconvolution, receiver ensemble deconvolution, statics correction, F-K filtering for noise, zero phase spiking deconvolution and model dephasing. A signal directly proportional to the actual signal that the vibrator is sending into the ground is used in pre-processing. The vibrator motion is measured to provide a signal that is used to process the data. The data is divided by the relative of the actual transmitted signal in frequency domain.

摘要： The multidimensional ECG processing and display system of the present invention is used with an electrocardiographic (ECG) monitoring system. Input ECG data from multiple, sequential time intervals is collected and formatted into a two-dimensional matrix. The two-dimensional matrix is decomposed using singular value decomposition (SVD) to obtain its corresponding singular values and singular vectors, a compressed form of the matrix. The singular vectors are analyzed and filtered to identify and enhance signal components of interest. Selected singular vectors are transformed into their frequency domain representations by the Fast Fourier Transform (FFT), or related techniques. Certain data elements in the two-dimensional matrix are enhanced or diminished by modifying the singular values within groups of singular vectors to enhance certain objects that are associated with the ECG data and to diminish other features within the data. The enhanced data is expanded back into its original form and features in the ECG data are displayed as opaque objects within a transparent data cube.

摘要： A method for processing seismic vibrator data. The method utilizes a deterministic signature deconvolution of the vibrator data to compress the impulse response of the data resulting in sharper, clearer seismic images than are possible using cross-correlation techniques. The method may be used in place of or in addition to cross-correlation. Further, the method may be implemented in either the time domain or the frequency domain.

摘要： In seismic exploration, aliasing caused by coarse sampling along a line of exploration is corrected by trace interpolation. The interpolated traces are obtained by inserting zero amplitude traces between seismic traces. Transformation into the f-k domain and filtering of the aliased regions in the f-k domain produces properly interpolated traces when transformed to the x-t domain.

摘要： It has been found that by treating seismic data as damped oscillatory responses of earth layers in the form of resonating layer bars of rocks, data values, termed alpha values, can be obtained which yield an indication of subsurface composition. Seismic data are accordingly processed by obtaining an indication of the frequency-amplitude spectrum of each successive portion or data window of a seismic trace, determining the half-power points of each such spectrum for the trace, obtaining from the half-power points the alpha value for each trace and recording or plotting the alpha values. The alpha values obtained according to the present invention have been found to be useful in lithologic identification and in obtaining porosity information. The present invention is a calculator or digital data processing computer for obtaining such alpha values from field seismic data.

摘要： A method for extracting predetermined types of electrical signal data from an overall composite of time analog signal input information, the method consisting of constructing an ideal filter for each of selected electrical signal components of an input signal group, such filter construction being carried out by determining the pseudo-inverse or generalized inverse of a polynomial matrix as determined for the particular input signals to be examined, with application of the polynomial matrix for preadjustment of a multichannel pattern discriminating filter which, when energized by the input signals under examination, will produce separately the requisite selected electrical signal component outputs. Apparatus for carrying out the method may consist of plural channels of time domain filters connected in series with a weighting device for convolving input electrical signals; each of the convolution filters is adjusted to function at predetermined times and amplitudes in accordance with the matrix function or operator determined for selected signal component functions of a particular set of input electrical signals.

摘要： A computer apparatus for and computer performed method of obtaining a wide band representation of seismic reflection amplitudes. The seismic trace is successively truncated, each of the successive truncations is successively Fourier analyzed, and each center frequency component amplitude of the successive Fourier analyses is computed. The effects of successive truncation on the resulting center frequency function are then removed through the use of an optimum separation operator.
