摘要

综合应用钻井、录井、侧井、地震、试油、采油等资料及相关研究技术和方法 ,对欢 62 3块馆陶组绕阳河油层特稠油油藏地质特征和成藏条件进行了研究。其结果 :该油层单层厚度大 ,油源丰富 ,后期的构造运动使原油发生稠变 ,形成了特稠油油藏 ;该油层为一个ES向倾斜的单斜构造 ,油层发育 ;储层具有高孔渗 ,非均质性较强的特点 ,原油密度大、粘度高 ,开采该油藏需要通过蒸汽吞吐升温、降粘来实现
Geological characteristics and reservoir forming conditions of super heavy oil reservoir in Raoyanghe formation, Guantao formation in Huan 623 block have been studied by applying drilling, E-logging, mud logging, seismic, oil test and production data and related technologies comprehensively.The studied formation features thick single layer and prolific oil resources. Structural movement during later period thickened the oil contained forming extra heavy oil reservoir. Furthermore, it is a Es trend dipping monoclinal structure and oil layer developed with high porosity and high heterogeneity. As for the recovery, it is necessary to increase temperature and reduce viscosity by using steam soaking because of high density and viscosity of the crude.
