摘要
通过对油气田上方烃的微渗漏和分异作用及其在地表土壤中的吸附叠加方式的研究 ,认为目前通常所用烃指标的单组分数据统计背景和划分异常的方法存在较大的缺陷 ,提出利用烃多元组分相关综合特征确定背景并筛选出各背景中与油气藏有关的烃异常的新思路。该方法通过在已知油气田上的应用 ,证明其效果十分显著 ,与单一烃指标方法相比 ,大大缩小了勘探靶区范围并提高钻探成功率 。
Based on the research of the character of hydrocarbon s migration and fractionation upon oil gas deposit,have given a study on manners of hydrocarbon which was absorbed and superposed by surface soil,also gotten a new method of oil and gas exploration with surface soil hydrocarbon s interfix components multianalysis. Now the new method have been used in many oil gas deposits and it got a better notable effect,It may help to give a high successful rate for gas and oil resources drilling and it had great va...
