潜山风化壳碳酸盐岩油气藏地震响应特征研究及振幅横向差异属性在预测中的应用

PREDICTION OF CARBONATITE FISSURE RESERVOIR WITHHORIZONTAL SEISMIC AMPLITUDE DISCREPANCY

结合中国西部塔里木盆地的E地区潜山风化壳碳酸盐岩缝洞型油气储集体地震属性的预测工作,开展了技术方法和应用的研究。在充分掌握已知信息的基础上,通过反复试验对比,设计了地震属性预测油气储集体的整体研究方案。同时对其中采用的局域振幅横向差异性地震属性技术进行了地震属性与岩石物理性质之间关联性的分析研究。应用结果表明:利用局域振幅横向差异性分析潜山风化壳内部储集体结构和预测油气储集体具有较高的可信度,对井位的部署具有重要的指导作用。

Seismic properties play an important role in reservoir, which is difficult under complex geological condition. This paper discussed the prediction of carbonatite fissure reservoir in an area E of the Tarim Basin. With plenty of multi-discipline knowledge, the whole scheme of reservoir prediction is designed. The relation between seismic properties and geological meanings is researched by investigating the horizontal amplitude discrepancy, which was used to analyses the reservoir structure inside burial hill so as to predict oil and gas. This method shows higher reliability and important guidance in well locating.
