摘要： 在分析和解释准噶尔盆地东部阜东斜坡带速度谱资料的基础上,结合根据钻井、测井资料建立的本区两种精细砂泥岩压实模型,利用地震速度岩性解释系统VLIS)进行了层速度转换、谱算层速度校正及砂岩指数计算误差平滑和校正,并分别计算了中上侏罗统石树沟群的层速度和砂岩指数。通过对研究区地震相和沉积相特征的分析认为,本区砂岩指数高值区与前积、充填相等对应,表明本区物源主要来自东北方向,这就为阜东斜坡带有利储集相带的预测提供了依据。

Abstract: The velocity spectrum data from Fudong slope belt in eastern Junggar basin are analy zed and interpreted, the compacting models oftwo types of detailed sandy mudstone using drilling and well log data are developed. Based on these, the conversion of interval velocity,correction of spectrum-based interval velocity and correction and smoothing of sand exponential-calculated error are conducted using seismicvelocity lithological interpretation system (VLIS), obtaining the estimated interval velocity and sand exponent of Mid-Upper Jurassic Shishugougroup, respectively. Through seismic interval velocity analysis and lithology prediction, integrated with characteristics of seismic facies andsedimentary facies, the high sand exponent areas are corresponding to foreset and filled facies, which reflect that the source in this area is mainlyfrom deposits to east-north direction, and provide quantitative basis for predicting the favorable reservoir facies belts in Fudong slope belt.

Key words: Junggar basin, velocity spectrum, interval velocity, lithology interpretation, prediction
