摘要
长期以来,石油物探的主要对象是构造,不管这些构造是由什么岩性的地层所组成,也不管其中有没有油气。在区域测量阶段提供区域构造资料,在普查详查阶段提供构造圈闭,这几乎已是天经地义。但随着油气勘探的深入发展,随着地球物理勘探技术的不断提高,人们已经深深感到这样做是远远不够的了,而必须以构造、岩性和油气三者作为石油地球物理勘探的综合目标,实现构造、岩性、油气的综合勘探。我们认为这是当前加强石油天然气普查勘探,迅速增长石油天然气后备储量的一个重要方向。
Abstract
Structures have been the primary targets of petroleum geophysical exploration for a long time, no matter what lithological strata they were formed and whether there were any oil and gas in these structures. As a matter of fact, it is a common knowledge and an universally acceptable principle to offer the information about regional structure in the end of the period of regional survey and to offer the information about structural traps after reconnaissance survey and detailed investigation. With the deepening of the exploration of petroleum and the improving of the technique in geophysical prospecting, it is obviously far from enough to seek for structures only and it seems to be highly necessary to take the structure, the lithology as well as the hydrocarbon as a comprehensive target for exploration. A comprehensive exploration should be made with these three things as a whole. We consider this would be a very important measure for strengthening the reconnaissance survey and exploration of oil and gas, a very important measure of making a rapid increase in reserves of petroleum.
