摘要：

声发射活动对地质体载荷历史中的应力场期次和破裂强度记忆力特征,即Kaiser效应是声发射实验的基本原理,它是建立在测试岩芯或露头样品上的一种研究储层裂缝的新方法。以辽河古潜山油藏为例,此方法不仅能有效的划分潜山裂缝期次,亦能判别潜山储层破裂强度及性质等复杂地质问题,颇具应用前景。

Abstract:

Applying Kaiser effect as the basic principle of acoustic emission experiment to test core or outcrop samples is a new method of studying reservoir fractures.This method was used in the study of the buried hill oil pools in Liaohe Oilfields.It could not only distinguish effectively the fracture terms of the buried hill,but also could determine the fracture intensity of the reservoirs in the buried hill and their feature.The method is proved to be valuable in application.
