摘要

大地电场岩性探测技术是80年代发展起来的一项非地震地球物理勘探技术。该仪器的场源为天然低频电磁波，它来自太阳内部的核反应。这种低频电磁波，可以垂直透射地面，在每个深度都能反射回地面。大地电场岩性探测仪在地面接收来自地下不同深度的电磁波信息。经对资料分析加工，可了解地下地质情况。中原油田从1991年开始推广这项技术，几年的实践证明，该技术在地层划分、特殊岩性段的判别及储层（油气层）的检测等方面具有良好的效果，并建立了4种岩性剖面的解释模式。该方法具有不受地表条件限制，快速、高效、经济等一系列地震勘探不可比拟的优点。
The technology of geoelectric field lithology detection is a kind of nonseismic geophysical exploration technology developed in 1980s. The field source of the instrument is natural low frequency electromagnetic wave, which comes from the nuclear reaction in the inner of Sun. This wave can transmit the land surface vertically and reflect at every depth. The detection instrument receives the information of electromagnetic wave from different underground depth at surface. The subsurface geological condition can be knowe1dged by analyzing the data. The technology has been POpularized since l991 in Zhongyuan Oilfield. The practice in the several years proves that it has good effective to stratigraphic classification, discrimination of special lithologic intervals,detection of reservoirs (or oil and gas zones), and so on. The interpretation models of four lithogogic profiles are estabilished. The method has some advantages such as fast speed, high efficiency, low cost et al. but seismic exploration has not.
