The bigger average pore of the porosity system,the smaller size of the micro-residual oil droplet and the more dispersed micro-residual oil droplet after waterflooding, that is to say, when the average pore width is big enough,the micro-residual oil is mainly composed of isolated single-pore and dual-pores droplets whereas the blocklike remaining oil is hardly exist.

微观驱替效率随平均孔宽的增加而增加，孔隙大小决定微观剩余油液滴的大小，孔隙系统的平均孔隙半径越大，水驱之后微观剩余油的尺寸越小，分布越分散，也即当孔隙的平均孔宽较大时，微观剩余油主要是由孤立的单孔隙和双孔隙液滴组成，连片的块状剩余油几乎不存在。

In this study, we developed the ammonia sensing material by using MCM-41 impregnated with bromocresol green. MCM-41 is one kind of mesoporous molecular sieves. It can be applied to many fields due to well-defined pore shapes, narrow distribution of pore sizes, large pore volumes, high surface area, excellent thermal, hydrothermal, chemical and mechanical stability. And the bromocresol green dye is commonly used as a pH indicator with colorimetric from pH 3.8 to pH 5.4.

本研究之目的是结合变色染剂及中孔洞分子筛MCM-41进行氨气吸附，研究中所选择之变色染剂溴甲酚绿是一种偏酸性之大分子有机染剂，其变色范围在pH 3.8到pH 5.4；而MCM-41由於其孔洞大小分布范围狭窄、孔洞体积大、高比表面积、具有良好的吸附容积、表面反应性强及易於改质等优点，故期望利用此复合材料，经气体吸附达到氨的移除并同时在吸附饱和前能产生显色效果。
