摘要
有机生油论的各种指标虽然在客观上的确能够指导找油的实践,但它本身可能存在较大的问题。目前的生油理论其实质可能只是一种盖层指标以及和油苗相类似的直接找油指标。直到今天,谁也没有在实验室里证明低温下有机物(不管是陆相还是海相)可以生成石油。列举了有机生油理论目前存在的二十多个方面的矛盾,并指出最近出现不少新的情况却有利于无机生油理论。如果今后石油无机生成学说得到普遍接受,那么,人们将仍应主要在沉积岩中找油,仍旧要在盖层下面去找,不过由于打破了思想上的束缚,就会勇于开拓新区、新层系的勘探工作。人们也会注意去寻找与深断裂有关的油气藏。如果思想禁锢在有机生油论的框框里,就会贻误油气田的发现。
Organic source theory shows various indexes that do objectively play a role of guiding oil-finding efforts,but it could be in big issues for its own.Present source theory may only be substantially as a caprock index and a direct oil-finding index similar to oil seepage.U-Up to now,no one has proven by experiment that organic matter at low temperature(whether continental facies or marine facies)can generate crude.This paper lists more than twenty contradictions or inconsistencies existed in present organic source theory,and offers a lot of new situ-ations appeared recently which are in favor of inorganic source theory in contrary.For the future,if inorganic source theory is universally ac-cepted,sedimentary rocks,especially under the caprock,will still be targeted for oil,but one might have the courage to explore new areas and new sequences,thanks to breakthrough of thought bondages.Moreover,one may pay more attention to searching for fault-related reser-voirs.Otherwise,if one's thinking is astricted in frame of organic theory,a few oil-gas fields can be missed to discovery.
