摘　　要：方法　综合应用钻井、录井、地球物理测井、地球物理勘探、试油、采油等资料及实验研究技术和方法 ,对曙一区兴隆台油层超稠油油藏地质特征进行了研究。目的　为超稠油的开发提供有力的地质依据。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 ,形成了超稠油油藏。结论　该油层为一个 SE向倾斜的单斜构造 ,油层发育 ;储层具高孔、高渗、非均质性强的特点 ,原油密度大、粘度高 ,属超稠油油藏。开采该油藏需通过升温、降粘来实现。Method Combining data acquired from drilling, mud-logging, logging, geophysical exploration, oil testing and producing with experimental technique, geological features of super heavy oil reservoir in Xinglongtai formation, Shu 1 area was studied. Purpose To provide reliable gelolgical basis for developing super heavy oil. Result This formation features thick single layer at an average value above 2m, which is rich in super heavy oil reserve and later occurred thickening under structural movements and formed reservoir. Conclusion The studied formation is a monoclinal structure striking SE and oil-bearing layer developed. It features high porosity, high permeability, obvious heterogeneity. It belongs to super heavy oil reservoir since the crude has high density and viscosity. Raising temperature and reducing viscosity are main measures to exploit this kind of reservoir.
