| 摘 要： | 新研制出的一种三分量检波器,尾锥不动,能方便地调节其方位角和水平角,可保证同一测线上的检波器各分量的极性和相位一致,检波器与地面耦合良好;三个分量之间的隔离度大于20dB,保证了道间无串音干扰。三个检波器串联组合,有利于地震信号接收。通过数值模拟拟定出地震测线布设方位和观测系统,在采集试验中开展波场调查、偏移距试验、不同覆盖次数对比,以确定出合理的观测系统和采集参数,在四川山地获得了高质量的三分量地震资料,形成了一套实用的陆上三分量地震资料采集技术。

ACQUISTITION OF THREE-COMPONENTS OF 2D SEISMIC DATA IN MOUNTAIN REGIONS |
| |
| Abstract: | In this paper, a new designed three-component geophone is introduced, which consists of a direction control pole, a compass, three geophone cores and three fixed tail stingers. Its azimuth and horizontal angle can be conveniently adjusted to ensure the polarity and phase of three components of the geophone to be consistent on a seismic line. The segregation degree of three components is over 20 dB, which ensures no signal being able to cross between geophones. The three geophones connected by a linear array are beneficial for receiving seismic signal.Seismic line and layout are worked out by numerical modeling, the feasible layout and acquisition parameters are determined by the wave field investigation, offset test and comparison of various folds in acquisition testing. By the three-component geophones, the three-component seismic data with high quality are acquired in Sichuan and a series of practical acquisition techniques of land seismic data have been developed. |
