针对白音查干凹陷缓坡带腾格尔组薄互层含油砂层组的砂体分布问题,采用构建地质地球物理关系、地震多属性分析、波阻抗反演等方法进行了研究,研究结果表明:(1)该区砂泥岩薄互层砂岩的阻抗特征不明显,单一的储层预测方法不能有效地进行储层预测;(2)砂体在地震多属性分析预测结果上有很好的反映;(3)地震多属性能够精细描述砂泥岩厚度的横向变化,预测效果与实钻资料比较吻合。近来在近洼带预测目标上成功钻探了X27井,发现了富集区块,控制地质储量上千万吨,实现高效勘探,对断陷凹陷的岩性圈闭预测和油气勘探有一定的借鉴作用。

In view of the distribution problem of sand body in Baiyinchagan Depression gentle slope belt about Tengger group thin interbed oil sands level,we carry out the research with the methods of geological and geophysical relations,seismic multi-attribute analysis and wave impedance inversion. It is the results indicate in this paper that(1)The sandstone impedance characteristics of the thin interbed level is not clear and the single reservoir prediction method could not conduct reservoir prediction effectively.(2)The sand body has good reflection in seismic multi-attribute analysis.(3)Seismic muliti-attribute prediction can finely describe the lateral changes of the thickness of sand shale and the prediction effectiveness is consistent with the real drilling data. Recently,based on the depression belt prediction target,we successfully drilled the tin Well X27, and found out the rich block and controlled the geological reserves in ten million tons. The realization of efficient exploration provides a good direction for the exploration and development of the oilfield.
