黄土塬区天然气地震勘探的新进展
|
摘要
这是一个地震勘探实例。针对黄土塬复杂地形区、逆冲推覆构造带的复杂性,在冲沟区弯线数据采集方法、非纵测线数据采集技术方面,资料处理中的二维滤波、自动剩余静校正、静校基准面的选取等环节,以及地震资料的综合解释、重—震联合反演技术上,都获得了明显进展。这对中国复杂区的高分辨率地震勘探工作,具有一定的参考价值。
We have made much progress in collection of curve-line data in gully areas and collection of non-longitudinal measuring line data, 2D filtering, automatic residual statics, and selection of statics datum in the data processing as well as integrated interpretation of seismic data and gravity-seismic joint inversion technique, wich can let us well deal with the complication of topographic features and thrusting and nappe structures in the loess plateau region.
