莫里青盆地双阳组储层中岩石不稳定组分多 ,胶结物以敏感性强的粘土矿物和碳酸盐为主 ,孔隙结构为中孔细喉 ,储层物性差 ,原油石蜡沥青组分多 ,地层水矿化度低 ,存在潜在的敏感性。分析表明 ,储层填隙物中的粘土矿物、碳酸盐矿物是导致该区储层敏感性的主要因素。结合敏感性实验证实 ,本区储层的敏感性主要为中 -强水敏、盐敏和中等碱敏 ,酸敏性在盆地控盆断裂带不明显 ,但在缓坡带较强。建议在钻井、酸化等作业时注意防膨和控制注入流体的pH值及盐度 ,以有效地保护储层 ,提高油气勘探开发的经济效益。 There are many rock instability components in the Shuangyang Formation reservoir in the Moriqing Basin. The cements are mainly clay minerals and carbonate with high sensitivity. The pore structure is mesoporous and thin-throat, and the reservoir properties are poor. The crude paraffin asphalt component Many, low formation water salinization, there is potential sensitivity. The analysis shows that the clay minerals and carbonate minerals in the reservoir capping material are the main factors leading to the reservoir sensitivity in this area. Combined with the sensitivity experiments, it is confirmed that the sensitivity of the reservoir in this area is mainly medium-strong water sensitivity, salt sensitivity and medium alkali sensitivity. The acid sensitivity is not obvious in the basin controlled basin fault zone but strong in the gentle slope zone. It is suggested to pay attention to anti-swelling and controlling the pH and salinity of injected fluid during drilling and acidizing operations to effectively protect the reservoir and enhance the economic benefits of oil and gas exploration and development.
