地震测深数据处理系统的建立是为了利用现代技术,实现从野外观测到剖面解释的自动化处理。本研究中,模拟磁带记录通过相应的解调系统,使时间讯号与地震讯号分别送入计算机进行模数转换,其数字化的 PS 格式磁带又经过解编与拼装形成标准化的 CGG 格式磁带,各记录道的参数和观测数据分别被记入带头与数据块中。这种标准化的磁带格式便于进行国内外资料交流和调用产业部门的应用软件。该系统采用相关迭加技术使正点时刻的确定精度提高到5—10ms。利用 Robbins 公式高精度地测定了方位角和炮检距。绘制时间剖面图的程序具有简便通用和功能较全的特点。本研究结果已经用于实际工作中,取得了良好的效果。
Seismic sounding data processing system was established in order to use modern technology to realize the automatic processing from field observation to section interpretation. In this study, analog tape recording through the corresponding demodulation system, the time signal and the seismic signal were sent to the computer for analog-digital conversion, and its digital PS format tape has been assembled and assembled to form a standardized CGG format tape, the records Road parameters and observations were recorded in the lead and the data block. This standardized tape format facilitates the exchange of information both at home and abroad and in applications in the industrial sector. The system uses the relevant superposition technology to make the determination accuracy of the punctuality moment increased to 5-10ms. Using the Robbins formula, the azimuth and offset are measured with high accuracy. The program of drawing the time profile has the characteristics of simple and versatile functions. The results of this study have been used in practical work and achieved good results.
