地震属性分析在卡2区块储层预测中的应用

地震属性与储层参数之间并不存在简单直接的对应关系。利用地震属性进行储层预测时,需对所利用的地震属性进行有效分析,给特征明显的属性赋予明确的地质意义。以塔中南坡带卡2区块为例,利用地震属性技术,结合实际钻井和测井资料,对目的层段的生物礁滩体进行预测,预测了该区礁滩型储层的分布范围。

Application of Seismic Attribute Analysis Technique to Reservoir Prediction in Ka-2 Block

There is not a simple direct corresponding relationship between seismic attributes and reservoir parameters. The effectiveness of seismic attributes used should be analyzed when predicting reservoir quality by using seismic attribute, unambiguous geological implication should be assigned to seismic attributes with obvious features. Taking Ka--2 Block located at the southern slope belt in Tazhong Area as an example, thispaper has predicted the organic reef body distribution range of objective interval by using seismic attribute technique with the combination of actual well drilling and well logging data.
