摘    要:山东胶东地区为多期次岩浆活动与变质作用的产物,岩石以变质岩和岩浆岩为主。由于构造活动频繁,且处于断裂带上,岩石破碎带发育。本次科学钻探测井分析的主要任务是岩性识别与破碎带识别和划分。首先围绕岩性识别研究了多种测井交会图技术,实现了研究区钻遇的变辉长岩、片麻岩、二长花岗岩等的岩性识别,并总结了其测井响应特征。针对裂缝和破碎带分析,提出了应用主成分分析方法,并且识别结果与岩芯描述比较一致。上述岩性分析和裂缝、破碎带的测井解释结果对寻找黄铁矿石英脉起到较为重要的作用,也为综合地质信息的研究提供了可靠资料和依据。

关 键 词:测井资料  裂缝分析  岩性划分  黄铁矿  主成分分析法

Abstract:Jiaodong region of Shandong is created through multi-stage magmatic activity and metamorphism, which is lacated in a fault zone with frequent tectonic activities and development fracture zones. The area dominated by metamorphic and igneous rocks with complex lithology. The main purpose of scientific drilling in this area is to find pyrite-quartz vein associated with gold. Firstly, some crossplots are constructed to identify the lithology ion. Some rocks such as metagabbro, mixing rock, monzogranite can be distinguished from one another and their logs response characteristics are also summarized. For logs analysis fractures and broken zone, the principal component analysis method is proposed, and the recognition results are proved correctly by the core photos. The aforementioned logs interpretation results about lithology and fractured zone play a more important role and provide a reliable basis for the study of integrated geological information.
Keywords:Principal component analysis  Loess in Guanzhong basin  Snail shell fossil  14C-AMS dating.  Logging data  Lithology idenfication  Fracture analysis  Pyrite
