摘要
宝北区块为一典型的低孔低渗油藏 ,注水开采造成油层伤害严重 ,针对该油田强水敏地层的特点 ,开展了防水敏伤害的油层保护实验研究。研究结果表明 ,造成地层强水敏伤害的矿物主要为高岭石和蚀变云母。通过实验评选出了性能较好的粘土稳定剂 ,提出了防水敏伤害的油层保护措施 ,并在现场进行了试验 ,取得了满意的效果。
Baobei district belongs to a typical low porosity and low permeability reservoir.The formation damage is severe due to the water injection development.So,experiment and study of the formation protection of the strong water sensitive reservoir is necessary.The result of study shows the main water sensitive mineral are kaolinite and mica.The best clay stabilizer is chosen out through evaluation experiment,and the paper put forward the reservoir prrotection measures to prevent the water sensitivity.Field trials showed that the measures to prevent water sensitivity have better effect.$$$$
