复杂地区地震勘探成孔方法研究

Research on Complex Area Seismic Survey Hole Method

地震勘探作为较好的一种地质勘探手段,已由平原区转向复杂的山地和丘陵地区,而这些地区由于表、浅层地震地质条件较差,给地震从施工方法到采集数据的质量上都带来了很大的难度。而这些问题产生的最根本的问题是激发成孔问题,如果激发孔深较浅,势必要产生较多干扰波,影响有效波的接收。因此,要根据不同的表、浅层地震地质条件来选择不同的成孔设备,以期获得最佳的激发效果。本文主要针对不同的复杂地区,对如何选择合适成孔设备,以及它们所具有的适用条件,成孔深度等进行了分析和研究。

The seismic survey method as a good exploration method has been used from the plain to the complex mountainous region and the hilly area, but these areas because the surface, the shallow layers, seismic geologic conditions are bad, has brought the very great difficulty for the seimic from the construction way to gathering data quality. The most basic question is the hole question, if the stimulation depth of hole is shallow, will have to produce many disturbing waves, affect the significant wave receive. Therefore, must according to the different surface, the shallow layer seismic geologic conditions choose differente hole equipment in order to obtain the best stimulation effect. This article carries on analysis and research on how to choose hole equipment appropriately as well as the suitable comnditions and the hole depth under the different conplex area.
