Title: Method for investigating oil-and-gas deposits by seismic waves
IPC: G01V1/40
Filed: 2002-08-30
Abstract: The proposed method for investigating oil-and-gas deposits by seismic waves consists in exciting seismic vibrations in a spatial zone around the investigated well, determining the vectors of the displacement of direct longitudinal and lateral seismic waves at each seismic vibration reception point by using the three-component seismic profiling of the investigated well along its height, and processing the resulting data for determining kinematic and dynamic parameters that characterize the propagation of seismic vibrations. For exciting longitudinal seismic vibrations, a single seismic vibration source is used. The seismic waves are received concurrently at the points of the investigated well and the reference well. After ordering the data of the three-component seismic profiling according to the spatial coordinates of the controlled points, from the seismic signals corresponding to the axial and tangential components of the seismic wavedisplacement vectors, the time signals of the same type are defined that characterize the compression and the shift of seismic waves for the investigated and reference wells. The data for kinematic parameters that characterize the propagation of longitudinal and lateral seismic vibrations are used for determining the coefficients of elasticity under compression and displacement. The data obtained from the results of the time signal processing are used for the quantitative estimation of the dynamic parameters for each component and each reception point of the seismic vibrations according to the data obtained for the investigated and reference wells. The accuracy in determining the dynamic parameters that characterize the propagation of seismic vibrations is verified by the computer simulation of seismic vibrations. After correcting the dynamic parameters with consideration for the changing conditions in which seismic vibrations are excited and filtering the seismic signals that propagate at the upper rock layers, the dynamic parameters of the pulse characteristics, dynamic seam viscosity coefficients, and seismic waves absorption factors under compression and displacement are determined for all the investigated seams. The values of the absorption factors under compression and displacement are used as indicators that characterize the presence and types of hydrocarbons in the seams as well as for determining the coefficients that characterize the attenuation of the amplitudes and the dissipation of the power of seismic waves. By functional dependences that consider for the conditions of rock deposition, the data obtained are transformed into the data for parameters that characterize the properties of the seams and used for determining the availability of an oil-and-gas deposit. The present invention provides the possibility to enhance the reliability of data in investigating oil-and-gas deposits. 2
