Joint quantitative analysis of properties of three-dimensional observation systems and its applications
The design of observation systems is an important part of data acquisition in seismic exploration.Its design quality directly affects whether the obtained data can meet the requirements of geological tasks and the quality of the data.A conventional attribute analysis of three-dimensional observation systems generally relies on independent evaluations based on the geometric distribution properties of the designed observation system's shot points(shot spacing,channel spacing,shot-line spacing,receiver-line spacing,receiver-line number,shot number,and receiver number),as well as coverage counts within bins,shot-receiver offset,and other factors combined with independent evaluation to support technical design.However,inde-pendent analysis and evaluation results may be confusing since each factor is interrelated and closely connected.This article in-troduces a quantitative analysis and evaluation method for observation system attributes,which comprehensively analyzes the shot point distribution properties,coverage count distribution,mesh element properties,and design for the target layer of three-dimensional observation systems.Finally,a comprehensive quantitative factor value for observation system attributes is ob-tained,directly comparing different observation systems for geological tasks.This significantly reduces the dependence on the designer's experience in evaluating observation system design.The evaluation of design results is more concise,scientific,and reasonable.This multi-attribute joint quantitative analysis is feasible after practical application in seismic exploration design.
