Optimization analysis method of seismic acquisition scheme evaluation and its application-Taking Fukang sag in Junggar Basin as an example
Most exploration areas in the Junggar basin are in the desert Gobi area.Due to the strong absorption and attenua-tion near the surface and various types of noise,the"two widths and one height"seismic acquisition under"enhanced"parameters is often used to improve the quality of collected data.Under the background of"improving quality,increasing efficiency and efficient exploration",from the perspective of technical and economic integration that takes into account both data quality and acquisition cost,evaluating existing acquisition schemes and proposing optimization schemes have become the focus of attention and research in the region and the industry.By analyzing the multi-block"two widths and one height"seismic acquisition scheme implemented in Fukang sag of Junggar Basin in recent years and combining it with relevant theoretical research,this paper puts forward an evalua-tion and optimization process of the acquisition scheme based on a quantitative relationship.It draws relevant conclusions that each acquisition scheme in the study area is appropriate or needs to be further optimized providing effective guidance for the next optimi-zation design.This provides practical guidance for the next optimization design of the acquisition scheme in the study area.
