摘要：

在覆盖区,断层隐蔽于地下,但因其常伴有与原岩成分、结构、构造有明显差异的构造岩,故应用声波测井信息也可以较好地鉴别其位置及力学性质。

Abstract:

The mechanical properties of four faults concealed by loose Quarternary deposits in Shengli Oilfield are studied with the information of acoustic log-ging in the light of principals of mechanism geology.Various characteristics of time difference anomaly have been traced in faults of different mechanical properties,a new method for identifying them is simultaneously turned out in this paper.It is proved in the living example researched that tectonites within compresive fault belt give rise to a clearly smaller time difference of acousticwave than those of lithologically the simillar non-tectonites,that is to say,a faster acoustic velocity is transmitted by the former;on the contrary,a lar-ger time difference of acoustic wave have recorded in tectonites within tensionalfault belts,i.e.the acoustic velocity within these belts is lower.
