Abstract
This is a translation version of the lecture made by Prof. R. W. Klusman in 1989 on the law of surface geochemical exploration of petroleum. Described are an outline of surface geochemistry, reactions near the ground surface by microseepage of hydrocarbon, survey methods of microseepage of hydrocarbon gas to the ground surface from the gathering area and the problems. In direct survey methods, hydrocarbon gas in soil pores is usually sampled for concentration measurement. Gaschromatography is mostly used for analysis. Besides the conventional instantaneous sampling, there is a method in which sample gas is accumulated not in short-period variations, but in a certain period, in soil where absorbent is buried. There is another method in which gas is removed or acid-extracted from soil particle surfaces naturally adsorbing gas. As indirect methods, there are biogeochemical methods using microbe, carbonate minerals and plants, and a method by air-borne magnetic survey, an iodine method, a trace element method, a gamma radiation survey of clay minerals and an He method. In the surface geochemical exploration method, no information on the depth, capacity of petroleum formation and faculty of oil wells is obtained. 375 refs., 137 figs., 4 tabs.
