塔里木盆地轮台地区低幅度构造圈闭落实技术及其应用
|
摘要
为了落实塔里木盆地轮台地区低幅度构造圈闭,通过三维地震精细解释,应用层位精细标定、自动追踪、相干体属性及变速成图技术,准确落实了区内局部构造。并通过对已发现油气藏的测井、地震资料的地球物理响应特征分析,发现油气层砂岩速度低,泥岩盖层速度高,油气层具有低频、强振幅特征。利用属性分析、含油气检测技术对落实构造的储盖组合、含油气性进行分析和预测,应用效果良好。
This paper aims to identify low-amplitude structural traps in the Luntai area in the Tarim Basin.Regional structures in the study area are accurately located by means of precise 3D seismic interpretation and technologies such as fine calibration for horizon,automatic tracing,coherence attribute and variable velocity mapping.Analyses of geophysical response characteristics of logging and seismic data of the known oil and gas pools reveal that the velocity of reservoir sandstone is low while the velocity of mudstone cap rock is high,and the hydrocarbon-bearing zones have features of low frequency but high amplitude.Further,attribute analysis and hydrocarbon detection technologies are successfully used to analyze and predict the reservoir-seal combination and hydrocarbon potential of the identified structures.
