摘要 鄂尔多斯盆地东部上古生界储层水锁伤害较强,水锁效应已成为影响该地区油气田产能的一个重要因素。通过水锁伤害试验分析了鄂尔多斯盆地东部上古生界储层水锁伤害情况。试验结果表明,研究区储层水锁伤害程度总体表现为中等偏强,其纵向上4个层位的伤害程度大小顺序依次为山1段、山2段、太原组、本溪组;中值半径、渗透率与该研究区储层水锁伤害程度呈负相关性,而岩屑、胶结物与该研究区储层水锁伤害程度呈正相关性,即含量越高的储层水锁伤害程度越大。 Water locking damage is strong in the Upper Paleozoic reservoir of the eastern Ordos Basin and the effect of water lock has been an important factor affecting the productivity of oil and gas in the region.It analyses the situation of the damage of the Upper Paleozoic reservoir in the eastern Ordos Basin by water locking experiment in the paper.The experimental results show the water locking damage to the reservoir in the area is medium to strong and longitudinally the damaging order is Shan1Section>Shan2Section>Taiyuan Formation >Benxi Formation.Median radius and permeability are in negative correlations with the damage degree,while the content of cuttings and cement is in positive correlation with the damage degree,that is,while the higher the content is,the greater the damaging degree would be in the reservoirs.
