【摘要】 利用岩心、测井和三维地震资料对奥里诺科重油带M区块开展高分辨率层序地层学研究。确定了不同资料的层序界面识别标志;分析了不同级别旋回的特征。将研究区主要目的层Morichal段分为3个Ⅲ级层序,7个Ⅳ级层序和13个Ⅴ级层序。通过单井岩心描述、连井测井对比和地震大范围横向约束对比,建立了研究区Morichal段的层序地层格架,为下一步储层预测和油藏精细描述工作提供重要的依据。更多还原

【Abstract】 The high resolution sequence stratigraphy on M block in Orinoco heavy oil belt was studied by using core data,logging and 3D seismic data.Features of sequence boundary in all available data were identified,and the characteristics of different levels of cycles were analyzed.The Morichal member in target zone was divided into 3 Grade Ⅲ sequences,7 Grade Ⅳsequences and 13 Grade Ⅴsequences.Based on the integrated research of core data description in single well,logging data correlation in wells and large scale horizontal correlation constrained by 3D seismic data,the high resolution sequence frame of Morichal member is established,it provides important basis for future reservoir prediction and description.更多还原
