【摘要】 以北黄海盆地东部坳陷为例,针对目标区特低孔特低渗储层特征,提出了应用有色反演与GR重构反演相结合有效识别砂泥岩的预测技术;针对目标区裂缝储层特征,提出了基于地震数据体和力学研究的多属性聚类分析预测技术。应用效果表明,目标区GR重构反演所预测的砂泥岩展布与钻井实际情况较吻合,多属性聚类分析所预测的裂缝发育区分布与测井解释结果及试油产能都具有较好的对应关系,储层预测结果可信度较高,可以指导井位布置。更多还原

【Abstract】 For the extra-low porous and permeable reservoirs in the target area,Eastern depression,North Yellow Sea basin,a technique to effectively predict sandstone and mudstone was developed by integratedly using colored inversion and GR reconstruction inversion,and for the fractures in this reservoir,a prediction technique of multi-attributes cluster analysis was proposed on a basis of seismic data volume and mechanics studies.Their application results have indicated that the sandstone and mudstone distribution predicted by GR reconstruction inversion can quite accord with the actual drilling data,and that the fracture distribution predicted by the multi-attributes cluster analysis can correlate well with the log interpretations and testing oil productivity.Therefore,this reservoir prediction is more reliable and capable of guiding the well arrangement.更多还原
