银-额盆地岩浆岩地震反射特征及与油气关系分析

银-额盆地中、新生代岩浆活动频繁，侵入岩和火山岩极为发育。通过对侵入岩和火山岩的形成、产出条件、分布特点、岩石类型和岩相特征分析，从地震资料入手，以地震相分析的方法，将岩浆岩的地震反射特征分为侵入岩和火山岩，进而将火山 岩的地震相归纳为板状反射地震相、丘状或弧状反射地震相、楔状反射地震相、舌状反射地震相和蘑菇状反射地震相5种，解释了它们的地层涵义，并以此为基础提出了岩浆岩与油气的关系，分析岩浆岩的地震反射特征对油气勘探具有重要意义。

Relation Between Seismic Facies Characteristics and Oil - Gas of Magmatite in Yin' e Basin

In the Yin'e Basin,magmation were happened frequently in Cenozoic, also there are a lot of intrusive rock and volcanics. This paper analyses its forming mechanism, distribution, types and lithological characteristics of the intrusive rock and volcanics with seismic information. The magmatite seismic facies is divided into intrusive rock and volcanics, and furtherly the volcanics seismic facies is divided into plated, mounded or arcuated, wedged, tongued and mushroomed seismic facies, and interpretating their importance. Based on this, the relations both magmation and oil - gas is provided, finally, it is analyzed that the seismic facies characteristics is very important in hydrocarbon exploration.
