摘要
作者根据作为原油成分之一的脂肪酸及其相应的盐和酯,能部分溶于与油气伴生的地层水中,且可以通过构造裂隙等通道被带到地表,导致地表土壤成分变化之原理,曾对中原油田马厂一三春集试验区作了脂肪酸油、气化探研究:即通过对试验区291个土壤样品脂肪酸总丰度的定量分析;部分土样、原油样、油田水样的气相色谱、色谱一质谱以及碳同位素组成的对比、鉴定。最后,根据脂肪酸的总丰度异常圈出了石油勘探有利地区。
On the basis of the principle that fatty acid as one of the components of crude oil and relevant salts and esters can partly be dissolved in strata water associated with oil and gas and brought upwards to the earth surface along tectonic fractures, hence leading to the compositional variations of soils on the surface, the authos studied the application of fatty acid in oil and gas geochemical exploration in the test area of Machang-Sanchunji in the Zhongyuan oil field. A total of 291 soil samples were collected from the test area and analyzed for the total abundance of fatty acid. In the light of the total abundance of fatty acid in conjunct1on with the GC,CM and carbon isotope data of some soil samples, crude oil samples and oil field water samples, the target area for oil prospecting can be defined.
