Study on sedimentary microfacies of the key sedimentary units of the Fuyu oil layer in Toutai
Journal Title: Scholars Bulletin - Year 2016, Vol 2, Issue 2
Abstract
Abstract: Fuyu oil layer in Toutai oil field has entered the development stage, in order to improve the recovery efficiency, needs to understand the underground fine geological conditions, and the study of fine sedimentary microfacies provides a solid foundation for the geological study. Through core and thin sheet material observation, combined with logging and experiment data analysis research, show that this area belongs to the delta plain, delta front and meandering river sub phase, and identified a further twenty-three kinds of microfacies . Analysis of the important sedimentary unit F I 3a, F I 5a, F I 8a, F II 5a sedimentary microfacies and plane sedimentary characteristics and logging facies model, which is conducive to a correct understanding of the favorable facies belt and distribution characteristics, tapping the potential of the remaining oil laid the foundation. F I 5a and F I 8a sedimentary units are delta plain subfacies phase. F I 3a and F II 5a sedimentary units are delta front subfacies. Keywords: Toutai oil field, the important sedimentary unit, Feature of microfacies.
