多属性分析技术在准噶尔盆地腹部油气勘探中的应用
|
摘要
准噶尔盆地腹部侏罗系三工河组断裂系统复杂,断距小;储层厚度薄,横向变化快;断层及储层的精细刻画难度大。针对这些难点,采用GeoEast解释系统中的构造导向滤波及断层形态指数技术落实了小断层展布,利用多属性分析技术刻画了砂体分布,通过波形分类技术进一步优选出砂体厚、物性好的区域。经过研究,在前哨1井南侧低勘探区域预测了三个Ⅰ类储层条带,为该区下一步勘探部署提供了依据。
Jurassic Sangonghe Formation in the Central Junggar Basin is characterized by complex fault systems with small fault distance and thin beds with rapid lateral changes.It is very difficult to accurately depict faults and reservoirs.With tools provided by GeoEast Interpretation Sub-system,a comprehensive research is conducted.The distribution of subtle faults is identified with the structureoriented filter and fault morphological index;reservoirs are characterized with multi-attribute analysis;and favorable areas with good sand thickness and physical properties are further optimized by waveform classification.Based on the research,three favorable zones are predicted in an under-exploration belt,which provides a basis for the further exploration.
