断层研究在地震安全性评价和石油勘探工作中的对比分析

The Comparison Study on the Fault Research Methods in the Seismic Safety Evaluation and Petroleum Exploration

对比分析了地震安全性评价和石油勘探中,断层研究的内容和方法。两者研究内容都包括断层活动时代、位置、规模、产状、性质等,但地震安全性评价更关注断层在地表和浅层的状况,活动时代等;石油勘探更关注较深处断层的状况,能否形成断块圈闭是主要研究内容。研究方法都包括地质露头调查、重力、地磁、地震勘探、钻井等。

The research attention and detecting methods on the fault in the seismic safety evaluation and petroleum exploration are compared in this paper, including the activity age, location, size, attitude, characteristic of the fault etc. In the seismic safety evaluation, it pays more attention to the faults in the surface and shallow layers, and the activity age, which is the important factor to judge the earthquake magnitude, but in the petroleum exploration it pays more attention on the faults in the deeper, which is the key to form the fault-block traps or not. The research methods include geological outcrop investigation, gravity survey, geomagnetic survey, seismic survey, drilling-hole etc.
