摘要
勘探实践表明位于歧口凹陷南缘的埕北断阶区是构造、岩性—地层油气藏发育的有利区带,但该地区构造断裂复杂,储层砂岩以薄层、条带状砂体为主,且横向变化大,制约了勘探的有效开展。本文利用钻井资料结合多种地震地质技术手段对目的层沙河街组开展储层预测研究,在精细标定的基础上,应用地震属性分析、相干体分析、波阻抗反演、三维可视化等技术,对储层进行定性分析和定量描述,以求提高钻井成功率和取得更大的勘探效益。
Exploration practice indicates that the Chengbei step-fault zone where located in the south slope of Qikou depression is favorable zone of structure,lithologic-stratigraphic reservoir.It restricts exploration with complex structural faults,thin beds of sand and lateral discontinuity.Paper attempted to predict targets Shahejie reservoir by means of drilling data combined with variety of seismic geological technical.To improve drilling success rate and achieve great exploration benefits,study analyzed qualitatively and described quantitatively based on seismic attribute analysis,coherence analysis,wave impedance inversion,3d visualization technology and so on with fine labeling the reservoir.
