变质岩潜山储层地震波组特征分析与应用
|
摘要
变质岩潜山储层非均质性强,如何有效地预测裂缝分布、寻找储层发育有利区域是制约变质岩储层高效勘探开发的主要因素。在裂缝发育区,地震波传播速度下降、振幅增大、能量显著增强,储层岩性影响地震反射特征。物理模拟实验分析表明,地震反射为一组裂缝的综合响应,代表的是一个裂缝带,而不是单一裂缝,裂缝角度与地震反射角度基本一致。文中通过井震结合的地震波组特征分析,建立了5类地震波组特征与裂缝发育模型,提出了利用地震资料直接识别变质岩储层裂缝的新方法。该方法在大民屯凹陷变质岩潜山勘探开发中得到应用和验证,确保了水平井有利储层钻遇率高达70%以上,实现了规模储量发现和油藏的高效开发,对评价其他潜山油气藏具有重要指导意义。
The metamorphic rock buried hill reservoir has the characteristics of strong heterogeneity. How to effectively predict the fracture distribution and look for the favorable area of reservoir development are the main factors of constraining the efficient exploration and development of metamorphic rock reservoir. The seismic wave propagation speed decreases, the amplitude increases and the energy significantly enhances and the lithology impacts the seismic reflection characteristics. Physical simulation analysis shows that seismic reflection is a set of comprehensive response to fractures, representing a fracture zone, rather than a single fracture. The fracture angle is consistent with the seismic reflection angle. Through the analysis of well seismic with seismic wave group features, five kinds of seismic wave group features and fracture development models are established. A new way of using seismic data to directly identify the fracture of metamorphic rock reservoir is proposed, which is verified in the exploration and development of Damintun metamorphic rock buried hill, ensuring that the drilling rate for favorable reservoir of above 70%,effectively guiding reservoir discovery and efficient development and having important guiding significance for the evaluation of the other buried hill reservoirs.
