摘要:

深反射地震采集要获取地下深度超过30 km处的莫霍面信息,通常采用大药量炸药激发,炸药激发对生态环境影响较大,不符合绿色环保的勘探发展方向.本研究旨在探索采用可控震源实施深部探测的可行性,及与可控震源激发相匹配的最佳的接收方式.通过对辽东地区开展的可控震源和炸药激发对比试验分析表明,采用高精度可控震源EV56激发,SN5-5低频检波器2支串联的接收方式,可以获得较好的深层地壳结构图像.试验的成功,为后续采用可控震源进行深地地质探测提供了有效的科学依据,具有重要的实际参考价值.

Abstract:

Deep reflection seismic acquisition is to obtain information on Moho surface more than 30 km underground. It is usually used by large-volume explosive. The impact of borehole shooting on the ecological environment can not meet the green development needs. The purpose was to study the possibility of using vibroseis to perform deep seismic reflection acquisition and the best geophone pattern. Through comparison experiments in the Liaodong area, it is shown that the high-precision vibroseis EV56 and the low-frequency geophone SN5-5 can obtain a better image of the deep crustal structure. The success of the test provides an effective scientific basis for the implementation and research of the subsequent deep geological exploration project, and has important practical reference value.
