6、了修订。此次修订的主要内容有:在第1章“范围”的要求中，将“本标准适用于浅海、极浅海、河流、湖泊地区石油地震勘探所使用的气枪震源系统”修订为“本标准适用于水深大于1.5m的水域地区进行石油地震勘探所使用的气枪震源系统”。在第2章“规范性引用文件”中，删除了已作废的SY5294-91《海上石油作业定位测量技术规程》，新增加并引用了SYNC6054-2000《水陆交互带地震勘探资料采集技术规程》。新增加了“术语和定义”，主要是对“相干枪、组合枪、气泡比和峰峰值”的含义作了明确的解释。将原第3章“气枪震源类型的选用”修改为现第5章“气枪震源系统组合阵列的选用”。将原第4章“气枪震源系统的检查项目

7、及指标”修改为现第4章“气枪震源系统的检验项目、技术指标和要求”。在原第5章“试验工作”的内容中，将b),c)两个条款针对“地质任务”要求的内容，修改为针对气枪震源系统“激发能量”和“频谱”的要求，这样使气枪震源的使用技术更加完善，更加结合实际。将原第6章“气枪震源激发点定位要求”改为现第7章“气枪震源激发对测量定位系统的要求”，并针对测量定位系统新增加了现7.2条款的内容。原第7章“质量控制要求”中，由于其他采集技术的
