摘要
锦58井区下石盒子组盒1段以岩性气藏为主,储层横向非均质性强,砂泥岩互层,通过对已知井地震反射特征的分析并开展相应的地震敏感属性分析研究。紧密结合地质、地震、测井资料,深入细致地研究地震反射波组及反射结构特征,利用这些特征推测未知区地层及砂体展布,建立起从地震属性到储层定量化分析,通过统计本区56口实际钻井资料,振幅属性与实际钻井的符合率达到85%以上,表明该方法适用于本区储层预测,成为该区产能升级、井位部署依据之一。
The first member of Xiashihezi formation in Jin 58 well area is mainly lithologic gas reservoir with strong lateral heterogeneity and interbedded sandstone and mudstone. Through the analysis of seismic reflection characteristics of known wells, the corresponding seismic sensitive attribute analysis is carried out. Combining geological, seismic and logging data closely, the seismic reflection wave group and reflection structure characteristics are studied thoroughly and meticulously. Using these characteristics, the distribution of strata and sand bodies in unknown areas is inferred, and the quantitative analysis from seismic attributes to reservoirs is established. Through statistics of 56 actual drilling data in this area,the coincidence rate of amplitude attributes and actual drilling is over 85 %, which indicates that this method can predict reservoirs in this area. The effectiveness of measurement has become one of the bases for productivity upgrading and well location deployment in this area.
