【摘要】 以哈萨克斯坦南图尔盖盆地下白垩统为例,针对辫状河与曲流河复合沉积体的沉积特征,应用沉积学原理,以测井曲线组合特征为基础,结合岩心相和地震反射及地震属性特征,在纵向上识别出了辫状河河床滞留沉积、边滩、曲流河的泛滥平原和河床滞留沉积等沉积微相。在构造分析、单因素分析多因素综合等分析的基础上,应用地震综合预测技术,将地震属性和测井、岩心分析技术结合起来,有效消除地震研究的多解性,很好地预测了河流沉积体的平面展布情况。更多还原

【Abstract】 With the Lower Cretaceous in the South Turgay basin in Kazakhstan as a case study,we detailed the deposit features of comprehensive deposit body in the braided river and meandering river.Based on a combination of logging curves,cores,seismic reflection and seismic reflection attribute,braided channel lag deposit,beach,meandering river flooding plain and channel lag deposit in the longitudinal direction are identified in the sedimentary body of Lower Cretaceous formation,South Turgay basin,Kazakhstan.According to single factor analysis and multifactor comprehensive technology as well as structural analysis and combining earthquake prediction technology,logging and core analysis,we effectively remove more multi-solutions in seismic facies research,and hence effectively forecast the river sedimentary facies.更多还原
