【摘要】 地震波的吸收衰减与储层的含油气性直接相关。通过对地震波衰减属性的提取和分析,可以使我们更好地对储层的性质(含油气性)做出识别和判断,使地震资料的储层预测工作取得更好的效果。这里主要叙述了利用分频瞬时Q值属性识别和预测研究区夏子街组优质储层的方法流程及应用效果。通过与已钻井的资料对比分析得到,吸收衰减属性的应用效果较好,所得结果正确可靠,从而为该地区的油气储层预测提供了重要依据。更多还原

【Abstract】 The absorption and attenuation attributes of seismic wave is directly related to the reservoir properties.With the extraction and analysis of the absorption and attenuation attributes of seismic wave,we can make a better identification and judgment on the fluid properties of the reservoir,and achieve better results of reservoir prediction based on the seismic data.Using the method of absorption and attenuation attributes analysis,this paper describes the methodology used and effects of distinguishing and forecasting the highquality reservoirs of Xiazijie formation in the study area.By the comparative analysis with the drilling results,we can get correct and reliable results,which provides the basis for oil and gas reservoir prediction in the area.更多还原
