摘要
油气藏中的挥发组份通过上覆地层微裂隙渗漏到地表，形成烃类物质地球化学异常晕。遥感作为一门新技术，已有效地应用到地表油气微渗漏异常的探测。本文主要介绍国外在因烃类微渗漏而造成的油气田地表土壤变化、岩石蚀变和地植物异常等方面的研究现状，以及国外在探索其形成机制方面的进展，并介绍国外石油遥感专家利用各种遥感手段进行烃类微渗漏探测的有效方法，望能达到推动我国石油遥感研究进一步深入与发展的目的。
The microseepage of the volatile element in oil and gas through the cover layer to the surface produces ground geochemical anormal.Remote sensing as a new technology has been applyed in the prospecting of ground anormal indication of oil and gas.This paper mainly introduces oversea ground soil variation, rock alteration and geobotaincal anormal in oil site due to the hydrocarbon microseepage prospects forming mechanics of these phynomenon; provides effectical methods of hydrocarbon microseepage prospecting through utlizing remote sensing by oil experts and hopes to get the goal of further study and development of oil remote sensing.
