Research on water displacing oil experiment efficiency and influential factors of delta front different sedimentary mic-facies of Ordos Basin——A case history of sandstone reservoir mic-single split mould water displacing oil experiment of YanChang Forma

Using the example of sandstone reservoir mic-single split mould water displacing oil experiment of YanChang formation of JiYuan area,The water displacing oil experiment characteristic,efficiency and influential factors of delta front different sedimentary mic-facies of Ordos basins are studied in the paper.It is thought that the mic-single spli of different sedimentary mic-facies can show different water displacing oil experiment characteristic and efficiency,and the efficiency is relevant with the class of sedimentary mic-facies and microfissure.The porosity,permeability of reservoir,the displacement pressure and displacement ratio are important influential factors.
