| 摘 要： | 黄土塬区复杂的地表条件难以获得可供解释的物探资料,本文给出了勘探天然气的地震技术,在野外弯线地震数据采集中,冲沟区运用了弯线高分辨率技术;塬上区采用非纵测线和地震测深观测系统,大药量、深井和强化组合法的接收条件。初步解决了弯线地震资料处理中二维滤波、静校正、速度分析等技术难题。摸索出一套以地震为骨架,构造解释与岩性解释相结合,重力-电法-地震联合解释落实古生界天然气构造圈闭的综合物探解释技术,并以实例展示方法的有效性。

| Abstract: | Owing to complex ground feature of loess plateau, acquiring seismic data is difficult. The following measures are taken: in area of corrasional gullies, the high resulution technique of curved line is used, in smooth area on top of loess plateau, the nonvertical survey line technique is used, and the condition of receiving signals is intensified. Therefore several difficult problems in data processing are initially resolved. An appropriate method of integreted geophysical interpretation has been gotten, and it is applied to determig traps of storing natural gas in Palaeozoic. |
