【摘要】 为进一步探索黄土山地区地震采集的有效技术方法,本文以鄂尔多斯盆地苏里格南为例,在综合研究该区激发因素、接收因素和仪器参数的基础上,进行了大量的野外试验对比分析.结果表明,采用如下技术可获得满意的采集效果:1)针对含水黄土及胶泥等好的激发层位,单井小药量3～4kg、9～13口多井组合激发技术;2)4212.5m的大偏移距,2～3线的多线数,25m的小道距,120～160次的高覆盖次数,20个检波器线性组合检波等接收技术;3)采用90dB以上大动态范围,大增益,采样间隔1ms的高采样率,采样时间5s的长记录时间的仪器采集参数.更多还原

【Abstract】 In order to explore further the effective techniques for seismic acquisition method in loess Hill area,this south sulige of Ordos basin as an example,in comprehensive study of excitement factors in the area,receive factors and instrument parameters on the basis of contrastive analysis of a large number of field test,the results show that as technology satisfactory collection results: 1) water content of the loess and clay is a good excitation layer,single-well small dose 3~4 kg,9~13 number of combinations to stimulate multi-well excitation techniques;2) receiver technologies have 4212.5m large offset,Multiple line of 2~3 lines,25m group interval,120~160 times the number of high coverage,20 geophones combination of a linear combination and etc;3) the use of more than 90 dB dynamic large range,a large gain,the sampling interval 1ms of high sampling rate,sampling time 5 s long recording time of the instrument acquisition parameters.更多还原
