【摘要】 本文对同一地区不同地表条件下炸药和可控震源两种震源的激发因素及产生的地震记录进行了分析和比较,指出在山前带或砾石区可选择可控震源激发,而在沙漠区或农田区可选择炸药震源激发;在选择好激发岩性的基础上,力求在高速层顶面以下3～5m激发是获得较好的炸药震源记录的关键,而震动台次、驱动幅度、扫描长度、扫描频率等参数的正确选取同样是获得良好的可控震源记录的保障。炸药震源和可控震源的联合运用是复杂地表条件下获得高品质地震记录的有效途径。更多还原

【Abstract】 The paper carried out analysis and comparison of shooting factors of two different sources and seismic records produced in different surface conditions, and pointed out that the vibroseis is selected in foreland and gravel zones and dynamite source is selected as shooting source in desert area or farmland; on the basis of well-selected shooting lithology, we should make our effort to shoot in 3-5m under the top of high-velocity layer, which can get better records by dynamite source, and correct selection of parameters of vibroseis such as the number of vibrator, driving amplitude, sweeping length and frequency is also the guarantee that can acquire good records of vibroseis. Joint application of dynamite source and vibroseis is effective way to acquire high-quality seismic data in complex surface conditions.更多还原
