油气化探现状及发展方向

近年来,近地表油气化探技术发展迅速,主要表现在：①原有方法日趋完善;②研究开发了近１０种新技术,如Ｋ－Ｖ指纹,三维荧光指纹,导数紫外吸收光谱,微磁,大地磁电,热释光,遥感地化等;③提出了“油层氧化还原电池”新概念和“似源结构异常场”新论点等。多学科,多方法的综合应用和勘查领域的扩展（井中,海上）将成为该项技术今后的发展趋向,实例表明,油气化探技术预测效果显著。

PRESENT STATUS OF HYDROCARBON GEOCHEMICAL PROSPECTING AND ITS FUTURE

In recent years, near surface hydrocarbon geochemical prospecting has developed rapidly. Itshows that (1) the original geochemical methods are being perfacted; (2) about ten new techniques, such as K-V fingerprint technique, 3-Dimentional fluorescence fingerprint technique,derivative ultraviolet absorption spectrum analysis, micro-magnetic survey, magneto-electrictellurics survey, thermoluminescence radiometric survey, remote-sensing geochemical survey,are developed; (3) some new concepts, "oxidation-reduction cell of oil formation" and "similar source composition structural anomalous field" are proposed. Combined application ofmulti-disciplinary and multi-geochemical methods, and extansion of geochemical application(to well logging and offshore) are the future trends of hydrocarbon geochemical prospectingin the days to come. Some examples show that the technique has clear effects for predictingthe oil and gas potential.
