Abstract
According to the distribution scale, the remained oil can be classified into two types: macroscopic remained oil and microscopic remained oil. The types and distribution laws are the basis of development adjustment in late period of oilfield development, and have great significance for improving effect of water injection and enhancing recovery factor of the oilfield. In this paper, the types, genesis and distribution laws of the remained oil in the peripheral oilfields of Daqing Placanticline have been investigated by the comprehensive application of the following research methods, such as sedimentary microfacies method, dynamic analysis method and numerical simulation method. It reveals that the adaptability of sedimentary microfacies to well patterns, the matching relationship of well patten and fractures and the control degree of well patterns on sand body are respectively the main factors influencing the distribution of remained oil in medium-low permeability oilfields, low permeability oilfields and ultra-low permeability oilfields. According to the main controlling factors, the effective treatments for the potential tapping of different types of remained oil have been proposed, which has effectively guided the development adjustment and comprehensive regulation of oilfields.关键词
