摘　　要：针对深水地震拖缆长缆多道问题,提出一种采集仪器的质量控制方法。该方法通过主动与被动两种模式来实现,包含室内系统运行质量控制方法和水下拖缆数据采集质量控制方法。其中主动模式可以按需产生模拟或数字激励信号送至采集仪器,从而用于评价仪器关键性能参数指标;被动模式则可实时采集仪器运行过程中的各种状态参数,用以实现仪器运行质量的实时评估。基于该独立于采集仪器的完备质量控制方法,可以有效控制采集仪器的质量,保障数据采集的品质,极大地降低了勘探作业的风险。长期的实验室测试和海洋作业的结果均表明了该方法的正确性和可实现性。A quality control method of acquisition instrument is proposed to solve the problem of long cable and multi-channel of large-scale deep-water seismic streamer, including indoor system operation quality control method and underwater streamer data acquisition quality control method, which is realized by active and passive modes. In the active mode, analog or digital excitation signals can be generated on demand and sent to the acquisition instrument to evaluate the key performance parameters of the instrument, in the passive mode, various state parameters in the operation process of the instrument can be collected in real time to realize the real-time evaluation of the operation quality of the instrument. Based on the complete quality control method independent of acquisition instrument, the quality of acquisition instrument can be effectively controlled, the quality of data acquisition can be guaranteed, and the risk of exploration operation can be greatly reduced. The results of long-term laboratory test and marine operation show that the method is correct and realizable.
