Main controlling factors and predictive models for the study of the characteristics of remaining oil distribution during the high water-cut stage in Fuyu oilfield, Songliao Basin, China

The distribution of remaining oil is affected by a number of geological and engineering factors. However, previous studies have mainly focused on the effect of a certain factor or some factors on the distribution of remaining oil. Therefore, this research considers subaqueous distributary channels of Fuyu oil layer in the Fuyu oilfield as a case with following investigations: analysis of the controlling effects of micro-structure, sedimentary...
