综合物探在塔里木盆地英买力地区火成岩研究中的应用
|
摘要
在分析钻井、物性资料的基础上,利用高精度重磁力、建场测深、地震资料,综合研究了塔里木盆地英买力地区古生界内幕岩性、岩相及其分布规律。结果表明,区内火成岩岩性、岩相复杂,产状多样。既有溢流相,又有侵入岩相,还有次火山岩相和火山通道相;岩性主要以中酸性侵入岩为主。重磁电震综合解释是研究塔北地区火成岩的有效方法组合。
Based on the analysis of well drilling and physical property,using the high accuracy gravity and magnetic survey,the field modelling suvery depth,the seismic data,this paper makes a synthetic study of the Paleozoic Erathem interior lithology,lithofacies and their distribution rule.The result indicates that the lithology and lithofacies of the igneous rocks are very complex,and the occurrence is multiple in study area.They have both the flooding and the intrusive lithofacies,but also have the volcanic and the volcano vent lithofacies,and the lithology is mainly the middle acidic intrusive rocks. The synthetic interpretation of the gravity,magnetic,electrical,and seismic is an effective combination method to study the igneous rocks of the Yingmaili area.
