| 摘 要： | 作者在文中论述了利用已有地震资料解释成果，根据地质任务建立二维地质模型，在此基础上进行射线追踪模拟出单炮地震记录和自激自发射面，进而提出了一套对观测手系统的最大炮检距，首间距等参数进行论证的一些实用方法，所得结果验证了资料处理和解释的正确性和观测系统设计的合理性。

| Abstract: | This paper introduces a feasible method for analyzing parameters of the field layouts to improve data acquisition. First, a 2D geology model is built based on the geology task with the known seismic interpretation results. Then the shot records and zero-offset records of the model are modeled by ray tracing method. Upon the modeling results, the parameters of the field layouts such as maximum distance form shot to geophone, trace to trace distance etc., are determined. A real case verifies the correctness of the data processing and interpretation, as well as the reasonableness of the designed field layouts. |
