典型山间盆地地震勘探采集方法探讨

Researching of Seismic Exploration Acquisition Methods in Typical Intermontane Basin

我国西部广大地区多数盆地与周缘造山带之间均为高陡的构造山区。这些地区油气资源潜力大 ,但地震地质条件复杂 ,地震勘探资料采集困难。在本研究区中 ,采用了SN388地震仪、中密炸药激发、检波器组合并深埋检波器以及可变的观测系统参数 ,改进了施工方法。通过实验研究选取了合适的施工参数 。

There are high and cliffy tectonic mountain regions that lie between many basins and peripheral orogenic zones in the west of our country. In these regions, potential of oil resources is big. While seismic-geologic conditions are complex and the data acquisition of seismic prospecting is very difficult. We used SN388 seismic instrument, grouping and deep embedment geophone,variable parameter of viewing system in this researching area, thus improved construction ways. Through experimentation and study, better seismic cross was achieved than before because of proper construction parameter selection.
