水源水对储层的伤害与敏感性特征研究

Study on the Damage and Sensitivity Characteristics of Water Source to Reservoir

文章研究的试验样品源于A区块的取心井查27-1井,研究层位是该区块储层上宗巴音组。通过对水源水注入地层后对储层的伤害作全面的损害评价分析,侧重对储层岩石的基本特征和储层敏感性特征进行了研究,并结合储层物性、孔隙结构待征及注入水水质特征等方面对A区块水源水对储层可能造成的伤害做出了评价和预测。

The test sample in this study was from well Zha27-1,A coring well in Block A,and the study horizon was the Upper Zongba Formation of the reservoir in this block.Based on source water injection formation after A comprehensive damage evaluation of reservoir damage analysis,focusing on the basic characteristics of the reservoir rock and reservoir sensitivity characteristics are studied,and combining the reservoir property and pore structure characteristics and the injection water quality characteristics of A block water could cause damage to the reservoir to make the evaluation and prediction.
