原油在运移过程中,在流经各个岩层的过程中,经常把有关岩层的孢粉夹带在自身之中。因此,我们分析原油中的孢粉并与有关地层作对比,就能够探明这一原油起源于哪一岩层,又流经了哪些岩层。 从原油中分离孢粉的方法虽然早在1937年已出现,以后又陆续有人作了研究,但都不够理想。直到1964年国外才试验成功一种效果较好的方法。 Crude oil in the migration process, in the process of flowing through the various rock formations, often associated with the formation of sporopollen in their own. Therefore, when we analyze the sporopollen in crude oil and compare it with the related strata, we can find out which rock layer the crude oil originated and which rock strata flow through. Although the method of isolating sporopollen from crude oil has appeared since 1937, some people have made some researches in the future, but they are not ideal enough. It was not until 1964 that we succeeded in experimenting with a more effective method.
