Abstract: The purpose of exploration in Baiqiu block of Nanyang depression was mainly to find lithologic & structural reservoir,which required high resolution and wide bandwidth of acquisition data. Through analysis of previous seismic datarecording geometry,combining the characteristics of exploration target,the geophysical model was built. Based on this,started with acquisition bins,variety in main target layers' depth,folds of inline and cross-line data,decrease of"acquisition footprint",etc. ,carefully carrying on record geometry demonstration,optimization design and optimizing a recording geometry which has antinoise effect and effectively improve target layers' resolution and bandwidth. The actu-al application in 2006 of Baiqiu block three-dimensional seismic data acquisition has greatly improved the S/N and resolution,and well accomplished with the geological task.
