There are phyteral cell remainingpore , matrix pore and new -forming pore in coal. The pores of remaining phyteral cell mainly are complicated dentritic structure, and the effective porosity is high.
煤中发育植物细胞残留孔隙、基质孔隙和次生孔隙，植物细胞残留孔隙主要为复杂孔隙树结构，有效孔隙率高。

The controling factor of remaining oil distribution is pore configuration. Remaining oil is mainly in the middle and small pores currently.
剩余油微观分布特征主要受储层孔隙结构控制，目前剩余油主要分布在中小孔隙中。

The sheet is spooled and then reticulated to remove any remaining cell walls and to round off the internal pore struts to enlarge the openings between the adjacent cells.
