Main influence factors of water-in-oil emulsion stability
油包水乳状液稳定性影响因素分析
The profile control agent,with sodium silicate solution as host agent,was injected into formations in the form of water-in-oil emulsion,and reacted chemically with the calcium and magnesium ions in formation water after demulsification,then formed chemical precipitation to plug the high permeability zones.
为此,研究了适用于高盐油藏的新型调剖剂,其作用机理是让调剖剂在地层一定部位发生有效的作用,其主剂为硅酸钠溶液,以油包水乳状液的形式注入地层,破乳后与地层水中的钙镁离子发生化学反应,在地层中产生化学沉淀,封堵高渗透层。
