作者提出的有效生油岩,系指成熟生油岩中能够排出或扩散出已生成烃类的那部分生油岩.本文除详细介绍划分有效生油岩和无效生油岩的方法和步骤外,还研究和分析了影响有效生油岩发育和分布的各种地质因素,以及有效生油岩与油气藏之间的密切关系,并明确指出有效生油岩才是油气藏形成的真正油(气)源岩.

In this paper, the concept of effective source rocks refers to those of source rocks in which the hydrocarbons already generated have been expelled or diffused out from their mature source rocks. Not only the meth-ods and procedures are introduced in detail to distinguish the effective source rocks from ineffective ones,but also the various geological factors influencing the development and distribution of effective source rocks are discussed,and the relationship between the effective source rocks and oil/gas pools are studied as well. It is pointed out that only the effective source rocks are the real source of oil and gas.
