高空间采样资料品质一体化技术研究

Research on Integration Technology of High Spatial Sampling Data Quality

高空间采样技术是地震勘探的发展趋势之一,但高空间采样成本倍增,制约了该技术的进程,用最小的投资获得最高的回报是采集考虑的主要问题,控制成本的关键是选择适用技术。在一体化勘探中,采集资料品质贯穿采集、处理和解释,现从技术经济一体化角度出发,首次以资料品质量化分析这一主线,将反演和正演结合一起进行论证,确定预采集资料品质范围,以预采集资料品质为技术目标,进一步量化分析,优选高空间采样的炮、道密度,实现勘探效益最大化,具有较大的应用前景。

The technology of high spatial sampling is an inevitable trend in the development of seismic exploration.However,the cost of high spatial sampling doubles,which restricts the process of the technology.The main problem to be considered in acquisition is how to obtain the highest return with the smallest investment.The key to control the cost is selecting the appropriate technology.In integrated exploration,the quality of collected data runs through the whole process of collection,processing and interpretation.From the perspective of integration of technology and economy,it is the first time to demonstrate the main line of quantitative analysis of data quality,and determine the quality range of pre-collected data combining the inversion with forward modeling.It takes the quality of pre-collected data as the technical objective to make further quantitative analysis and optimize the density of shot and channel of high-spatial sampling,which has great application prospects to maximize exploration efficiency.
