基于可控震源高效采集的单炮智能化评价方法的研究与应用

Research and Application of Intelligent Evaluation Method of single gun based on High Efficiency Acquisition of Vibroseis

近年来,可控震源高效采集方法越来越成熟,不仅施工效率与日俱增,而且采集模式更加灵活多变,这在某种程度上给与之相应的质控工作提出了更高的要求。基于快速实现自动分析、评价与质控可控震源施工震次的目的,通过研究Sercel 428仪器和震源DSD箱体返回资料与可控震源施工状态参数之间的关联特征,制定可控震源扫描震次的室内质控和评价流程,实现有效震次的智能化评价与统计,及时制定次日野外施工计划。通过自适应扫描DSD箱体数据的方法,自动评判被误判的潜在有效震次,并提取GPGGA数据段进行计算,将其恢复为有效震次。通过该方法的应用和统计对比,完善有效震次评判标准,在一定程度上减少了因误判废炮而重新采集带来的耗时,缩短了野外施工决策时间,辅助保障项目的快速高效运作。

In order to quickly realize the automatic analysis,evaluation and quality control of vibroseis construction earthquake number,the laboratory quality control and evaluation process of vibroseis scanning earthquake number is formulated by studying the correlation characteristics between the return data of Sercel 428 instrument and vibroseis DSD box and the construction state parameters of vibroseis,so as to realize the intelligent evaluation and statistics of effective earthquake number and make the field construction plan of the next day in time.Through self-adaptive scanning of DSD box data,the misjudged potential effective earthquake number is automatically evaluated,and it is restored to to effective earthquake number through extracting GPGGA data segment.The application and statistical comparison of this method improves the evaluation standard of effective earthquake number,reduces the time-consuming of reacquisition due to misjudgment of abandoned gun to some extent,shortens the decision-making time of field construction and guarantees the rapid and efficient operation of the project.
