Abstract
This paper discusses the sedimentary microfacies features of Menggulin pool in conglomerate by comprehensively using observation and analysis of core, data of log and researching sedimentary characteristics, log feature, reservoir feature and distribution of sedimentary microfacies. The authors research comprehensively the effect of sedimentary microfacies on the oil and water movement law and production state by means of analysis. The research result shows that there are abraided river delta plain, delta front, and so on. There are conglomerates of five sedimentary microfacies, and there are varieties of rocks and reservoir features in microfacies. The microfacies control oil-bearing content, distribution of conglomerate, even the movement law of oil and water, and distribution of remaining oil.
