摘要
黄土塬山地历来是地震勘探最困难的地区之一,以沟中弯曲测线和塬区直测线二维地震勘探为主要工业化油气勘探方式。山地三维地震勘探在黄土塬山地的设计思想和成功实施为该地区的油气勘探提供了又一新的途径。该文描述了中国首例黄土塬山地网状三维地震勘探应用效果。
It is a real challenge to carry out seismic survey in loess tableland.Due to its particular geologic features,we always adopt the method of 2D seismic survey with crooked lines in valleys and straight lines in this area,which is limited for the exploration.The technology of reticulate 3D seismic survey in loess tableland is put forward here.The characteristics of the primary sources and the related processing techniques are discussed.The application effects on processing and geology are analyzed.The results show that the techniques of reticulate 3D seismic survey are significant for the oil-gas exploration in the loess tableland.
