鄂尔多斯盆地延长组中下部组合油气勘探开发程度相对较低,超低渗储层分类与评价是制约该组合层系油气勘探开发的关键。选取可动流体百分数、主流孔喉半径均值、启动压力梯度、黏土矿物含量以及原油黏度作为低渗储层评价指标,建立评价体... 鄂尔多斯盆地延长组中下部组合油气勘探开发程度相对较低,超低渗储层分类与评价是制约该组合层系油气勘探开发的关键。选取可动流体百分数、主流孔喉半径均值、启动压力梯度、黏土矿物含量以及原油黏度作为低渗储层评价指标,建立评价体系,运用模糊数学理论,建立模糊数学模型,对长9储层进行定量评价,进而建立储层评价体系。研究表明,富黄地区长9储层主要为Ⅰ类、Ⅱ类和Ⅲ类储层,不含Ⅳ类储层。通过对富黄地区长9储层和沉积相平面图对比分析,储层分级结果与有利沉积相储层展布有较高的契合度,以期为延长组超低渗油气勘探和开发提供指导。 展开更多

Li Dongyang’s Gediao theory(格调说)advocates the style and tune of poetry,which has profound influences on later literati in the Middle and Later Ming Dynasty.This theory is the product of the time,put forward to complain about Taige style(台阁体)and to deal with the current problems under a subtle circumstance.It seems that Li Dongyang emphasized the metrics of poems,but in fact he aimed at putting renewed emphasis on the essence of Tao and the aesthetic pursuit of innocence and nature of poetry by Gediao theory.He ultimately proposed the functional activity of Qi as the method of expressing Tao and combined the tradition of poetry music to express human nature,which makes Gediao theory a temporal and innocent poetry theory. 展开更多
