石油地质学是研究石油与天然气的地质的科学,是地质学中的一个分门。就实用观点讲,它对普查、勘探和开采上所起的作用,要比任何其他实用地质学如煤田地质学等为大,而从事于石油地质工作的人员,也要比其他地质学部门多得多。这是因为油气本身的特殊性,使得我们只有充分掌握了石油地质的原理和方法,才能够有效地发现或扩大急迫需要的石油资源或合理地指导油田的开发和开采。同时,由于石油工业的厐大发 Petroleum geology is a science that studies the geology of oil and gas and is a division of geology. In practical terms, its role in census, exploration and extraction is greater than in any other practical geology such as coalfield geology, and so is more personnel engaged in petroleum geology than in other geology departments Much more. This is because the peculiarities of oil and gas make it possible for us to effectively discover or expand the oil resources that are urgently needed or to guide the development and exploitation of oil fields effectively only if we fully grasp the principles and methods of petroleum geology. At the same time, due to the huge oil industry boom
