采集参数选取的优劣直接关系到野外地震资料质量的高低。作者经过多年海上地震调查实践，总结了一套实用的采集参数选取原则与验证流程。首先结合南海北部某调查区以往的地震和地质资料分析，建立了典型的地震地质结构模型；根据现有调查设备的性能，利用专业软件Nucleus6.2模拟对采集参数选取的理论计算，比较不同采集参数组合的模拟结果，选择有利于调查任务的参数组合。对海上生产前模拟选用的采集参数组合做试验和验证，确定了最适合的参数作业。运用该套原则和流程精心设计，实验获得了高质量野外资料。

The authors have summarized a set of rules for choosing and verifying the main acquisition parameters in marine seismic exploration based on previous experiences of long-term practice. Firstly, an analysis is carried out for the selected area to establish a representative seismogeological model using various seismic and geologic information. Considering the current devices’ performances and options，they use a professional simulation software, Nucleus 6.2, to compute source parameters and to compare the response to various combinations of acquisition parameters, in order to choose a combination that is best adaptive to certain task. An actual exploration test is also carried out to verify the parameters’ combination chosen from the simulation test. Finally, the authors select the optimum Parameters’ combination and obtain quality data for production.
