陆地电火花震源试验初步分析

PRELIMINARY ANALYSIS OF THE LAND ELECTRIC SPARK TESTS

大港油田地调处;中国科学院电工研究所

本文简要介绍了陆地电火花震源装置及其工作原理。在大港油田,用这种震源做了六条试验剖面。当用二或三台这种震源组合激发时,其效果与井中8公斤炸药震源基本相同。电火花震源也可用于深井地震测井,测井质量合乎要求,效率也高。这种震源没有破坏性,没有污染,故适于居民区的勘探工作。现有电火花震源的缺点是在地面激发时,能量尚嫌不足。

In this paper, the land electric sparks and its principle of operation were introduced in brief. Six seismic lines were completed with theelectric sparks in Dagang oil field. When shooting with 2 or 3 of the electric sparks in combination, the effects were in essence just the same as those shooting in well with 8 kgs of charge. When it is used in deep well logging, the data quality will constantly meet the requirements and its efficiency is proved to be good. This kind of source has no damage and pollution, hence, it is suitable for the exploration in the region of civilization. The shortcomings of it is its energy is not large enough when shooting on the ground.
