摘要
针对高渗、高温、高矿化度砂岩油藏的地质特点,研制了GQ复合颗粒堵调剂。介绍了GQ复合颗粒堵剂堵调原理、性能、现场施工工艺及调剖效果,优化了颗粒堵剂的各种性能指标等。该堵剂主要用于砂岩高渗油藏的油井堵水和水井剖面调整,具有封堵效率高,抗温、抗矿化度强,有效期长,耐冲刷等特点。
A compound grain plugging and profile control agent of GQ type is developed based on the geological characteristics of sandstone reservoirs with high permeability, high temperature and high salinity. This paper introduces the principles, properties, field operation process and effects of this new agent. The property indexes of this grain plugging and profile control agent are optimized. It is mainly used for water plugging in producers and injection profile control in water injectors in sandstone reservoirs with high permeability. It has the advantages of high efficiency, large temperature and salinity tolerance, long effective period and strong flushing resistance.
