摘要(Abstract)：

海拉尔盆地贝301区块为中-低孔渗储层,储层敏感性矿物含量高。通过大量的静态与动态模拟实验,对储层的伤害机理与防治措施进行了室内实验研究,考虑在注水过程中控制粘土矿物的水化膨胀和分散运移,稳定注水井的注入能力。通过室内实验对现场即将使用的多种粘土稳定剂进行评价,优选出了与贝301区块油藏配伍的粘土稳定剂,形成了由室内实验到现场应用的注水开采技术。
Oilfield is a middle-low permeable reservoir in Bei 301 block of Hailaer. Sensitive mineral content is high. It should be to pay attention to reservoir protection in the process of waterflooding. Damage mechanism and prevention measure is analyzed through considerable static and dynamic experiment of simulation. Damage cause by flow rate sensitivity and water sensitivity and its influential factors were also estimated and discussed. So it is considered to add the clay stabilizer into the injection water to control the clay swelling and dispersion and migration so as to stabilize the injection capacity of the injection well. Many kinds of clay stabilizers which are going to used field are evaluated by the method of laboratory experiment. The optimum clay stabilizer which can be compact with Bei 301 block reservoir has been screened. It provides the techniques for water flooding development from laboratory experiment to field application.
