3d Seismic Observation System Is The Most Optimal Design Method

The purpose of this paper is to improving the wild seismic data S/N and resolution power which in the complex conditions, to ensure the seismic data imaging quality and reduce the cost of 3D seismic exploration. We develop 3D seismic geometry optimization design theory and methodology research. Aim at optimizing design of the conventional land 3D seismic acquisition parameters of the geometry, in 3D seismic acquisition, processing, interpretation of the integration trend, mainly for the following areas of research: (1) firstly observation of the conventional 3D design system guidelines, basic workflow, type and characteristics summarized; (2) integration of statistical experimental design techniques Taguchi, studied observation system optimization design process optimization function problems exist;(3) the experiment of practical information on the degradation of the observing system parameters, and study of the system design parameters and their impact on the degree of processing interpretation;(4) From the perspective of optimizing the function, studied the observing systems optimizing design methods that the offset will be evenly distributed and objectives based on geophysical parameters deviation of the smallest observation system optimization design methods.The study made the following progress and results: (1) sum up a detailed summary that conclude conventional 10 types of three-dimensional observation of the classification system, application conditions and their advantages and disadvantages, at the same time from the macro to dim-light patterns of geometry, we starting the current commonly used types of three-dimensional observation systems uniformly divided into four grades. (2) Based on statistical analysis summarizes the experimental design of three-dimensional seismic acquisition technologies designed to optimize specific objectives, conditions and restrictions of the model space and data space physics. Put forward the issues of five aspects of 3D design observing system optimization technology based on statistical experimental design. (3) Adoption of existing 3D seismic data "degenerative" processing test analysis, presented three-dimensional seismic data acquisition design of the five basic categories of geophysical parameters goals, and in three-dimensional geometry optimization designs three decisive geophysical target parameters. (4) Made in observing systems face Yuan attributes analysis, for the parameters of offset change rate that seized from quantitative descriptions of offset homogeneous, we established optimization objective function that on the basis of offset seized from being evenly distributed in the three-dimensional geometry optimization design. (5) Observing system design for three decisive proof parameters (maximum offset, covering number, instrumentation effective trace), bring forward the optimization objective function which based on the smallest geophysical parameters deviation of geometry design, use Excel spreadsheet, mathematical planning menu achieved optimizing design methods of conventional land wiring harness 3D geometry.
