可控震源模型设计浅析

DISSECTION ON MODEL DESIGN FOR VIBROSEIS

地矿部05项目工程处

可控震源扫描模型的设计对资料质量影响较大。本文通过对联合国派助我处专家唐纳德·费·基德先生提供的、能取得相对较好资料的离散扫描模型的分析研究,模拟出数学模型,并反推了扫描模型设计的原理和步骤,为野外生产现场设计提供了方便,使黔南碳酸盐岩裸露区的地震资料质量得到了改善。

To a great extent, the seismic data acquired is controlled by the setting of sweeping type for vibroseis'. This paper dissects a discrete sweeping model provided by Mr. Donald F.Kidd, an expert of the United Nation, who is authorized to give the help to our country in seismic exploration. This model has been proved to be successful in practice of acquiring seismic data and its philosophy and operating procedures are reversedly derived on the basis of its mathematical model which is also worked out in this paper. Those are fundamental to the design of sweeping model for vibroseis' in field and help to improve the quality of seismic data collected in the area of exposed carbonate rock in the south of Guizhou Province.
