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。 The Bay 301 block in the Hailar Basin is a medium-low permeability reservoir with high sensitivity mineral content. Through a large number of static and dynamic simulation experiments, the reservoir damage mechanism and prevention and control measures were studied in laboratory. Consideration was given to controlling the hydration expansion and dispersion migration of clay minerals during water injection to stabilize the injection ability of water injection wells. A series of clay stabilizers to be used in the field were evaluated through laboratory experiments. A clay stabilizer, which is compatible with Bayesai Block Reservoirs, was selected to form a water injection technology from laboratory to field application.
