【摘要】 潍北凹陷火山岩油气藏是一个重要的勘探领域。孔三段火山岩顶部为主要目的层,储层非均质性比较强,火山岩储层的有效预测一直是勘探难题。本文利用钻井和录井等地质资料,应用地震特征识别及地震相波形分类技术、多属性分析技术综合预测储层发育有利相带,预测结果与实钻井情况较为吻合。在此基础上,通过分析、对比各个曲率属性优缺点,找到了一套适用于该区的应用曲率属性预测构造裂缝发育带的方法,取得了较好的效果,从而证实该研究方法可有效指导该区火山岩勘探开发实践。更多还原

【Abstract】 The volcanic rock oil reservoir of the Weibei Sag is a significant area.The target stratum is the top of the third member in Kongdian Formation,which is more anisotropic, and it’s difficult to forecast volcanic rock reservoir effectually.In this paper, seismic character identification,seismic facies waveform classification and multi attribute analysis technology based on the data of well and logging are used to predict the favorable facies belt of reservoir development. the results tallies with actual drilling parameter. Then, by analyzing and contrasting the curvature attribute, there is a applicable method that can be used to predict the development-belt of the tectoclase,which is proved to be a effective way to guide the actual exploratory development of the volcanic rock in Weibei Sag.更多还原
