准噶尔盆地北缘石英滩地区火山机构的识别与描述
|
摘要
准噶尔盆地北缘石英滩地区石炭系火山岩具有较大的勘探潜力。通过研究地震剖面上火山岩的地震相特征,认为火山沉积相主要表现为强振幅板状反射、溢流相火山岩主要表现为中强振幅丘状-层状反射、爆发相火山岩主要表现为变振幅丘状反射。针对不同火山机构在同一属性中表现特征不同的特点,提取了对火山岩层反映较敏感的地震参数,如倾角属性、瞬时频率属性、均方根振幅属性,辅以相干体切片和时间切片,对火山机构进行预测。在研究区共识别出7个火山机构,为准噶尔盆地北缘石英滩地区的下一步勘探提供了有利依据。
The Carboniferous volcanic rocks in Shiyingtan Area of Junggar Basin have a good exploration prospects.Based on the characteristic of seismic facies from the seismic profile,the volcanic sedimentary facies mainly have a strong amplitude plate reflection.The overflow facies mainly have a mid-strong amplitude mound-layer reflection.The eruption facies mainly have a varying amplitude mound reflection.According to different volcanic edifices in the same attribute performances different characteristics,some sensitive seismic parameters are picked up,such as dip angle,instantaneous frequency,RMS amplitude,coherence cube and time slice,in order to explore volcanic edifice.Seven volcanic edifice were founded in research area,which can supply useful data for future exploration of oil and gas.
