油气化探是探索石油遥感勘探机理必不可少的手段之一，然而获取油气化探试验数据是一个相当复杂的过程，除涉及到地表各种地质，地貌条件外，还与地下油气藏的生、储、盖条件密切相关。本文在近年研究工作基础上，结合国内的一些典型实例，分析了油气化探效果与石油地质条件以及试验数据获取中的一些问题。

Oil-gas chemical exploration is one of neccessary tools for studyingthe mechanism of application of remote sensing techniques in oil-gas detecting. Butacquisition of the data of oil-gas chemical exploration is rather complicate.It hasa close relation to not only various surface materials and landforms but also the fo-rmation,reserves and covering strata of oil-gas pools.Based on recent studies thatwere carred out by the author and some other case studies in the country,a compa-rison of the results of oil-gas chemical exploration with oil-gas geology was made-and some aspects in acquiring the data of oil-gas chemical exploration was discu-ssed.
