摘要
本文介绍了四川盆地罗波溪构造山地高分辨率地震勘探的成功经验及为提高资料品质而采取的措施。内容包括:在野外采集中,采用高覆盖次数、高采样率、高频检波器和小道距、小组合基距、小地检距、较大药量及两个等高面等方法;在室内处理时,采用精细动静校正、分频处理、强功能去噪、双向反褶积、叠后处理等技术措施;在资料解释方面,综合利用层位标定、对比追踪、断层定量解释、Seislog剖面解释及道积分等技术c应用这套方法,拓宽了四川盆地中部油气勘探范围。
Authors detail both experience of high-resolution seismic exploration in Luo-duxi mountainous region in Sichuan basin and some measures for improving dataquality. The measures such as high fold, high sampling rate, high-frequency geo-phone, small group interval, short array length, small offset, big charge and twoisodepth planes, are taken in field data acquisition- Indoor data processing involvessome special methods, including detailed dynamic and static corrections, frequency-divided processing, powerful noise elimination, dual-directional deconvolution,poststack processing and so on. ln data interpretation, some effective ways areused, which are horizon determination, horizon correlation, quantitative fault in-terpretation, Seislog section interpretation, trace integration, etc- The applicationof these techniques widens hydrocarbon exploration in mid Sichuan basin.
