陆西地区火山岩相的识别方法及其在油气勘探中的应用
|
摘要
以岩石矿物学、沉积学、地球物理学和石油地质学为基础,对陆西地区石炭系火山岩相进行了分类;利用单井岩性特征、电性特征结合成像测井资料对已钻遇井进行火山岩相识别;依托精细层位标定技术,建立了火山岩相与地震响应特征之间的相互关系。在此基础上建立火山岩相模式,对火山岩相进行三维分析研究,并开展地震属性分析工作,为火山岩体的识别、火山岩油气藏的勘探提供依据。
Carboniferous volcanic facies in Luxi area are classified based on petrophysics, sedimentology, geophysics and petroleum geology. Combined with imaging logging data, the volcanic facies in drilled wells are identified using the lithologic and electrical characteristics of individual well. The relationship between volcanic facies and seismic response characteristic has been established by meticulous horizon calibration technology. On this basis, volcanic facies patterns are established. 3D analysis is applied to volcanic facies and seismic attributes are analyzed. It provides a basis for identifying volcanic rock body and exploring volcanic reservoirs.
