在油气勘探中,人们模索总结了多种多样的勘探方法,如地质调查、地球物理、地球化学等。多年来,前两种方法在找油找气中立下了汗马功劳,而对后一种,虽然早在二、三十年代就已提出或试用过,但由于当时技术条件远未成熟,因而一直裹足不前。近年来,鉴于仪器测试技术的突飞猛进,使地球化学勘探这一被冷落了的陈旧 In oil and gas exploration, people have explored a variety of exploration methods, such as geological survey, geophysics, geochemistry and so on. Over the years, the first two methods have made a significant contribution to the search for oil, and the latter, although already in the 1920s and 1930s, has been proposed or tried out, but due to the immaturity of the technical conditions at the time, it has been stagnant . In recent years, in view of the rapid development of instrumentation testing technology, geochemical exploration has been left out of the old
