针对稠油热采井出砂的特点 ,通过室内试验研制了适合于高温蒸汽井 (≥ 30 0℃ )的无机类固砂剂JNG - 5和JNG - 6。结果表明 :该固砂剂具有优异的耐高温性能 ,固砂强度高 (≥ 5MPa) ,对地层砂渗透率损害小(<2 0 % ) ,耐油水冲刷 ,成本低廉。现场试验表明该剂能有效地控制蒸汽驱井出砂 ,延长检泵周期
According to the characteristics of sand production in heavy oil thermal recovery well, inorganic sand fixing agents JNG - 5 and JNG - 6 suitable for high temperature steam wells (≥ 300 ℃) were developed through laboratory experiments. The results show that the sand-fixing agent has excellent high temperature resistance, high solid sand (≥ 5MPa), little damage to the permeability of formation sand (<20%), oil-water erosion, and low cost. Field tests show that the agent can effectively control the sand for steam flooding and prolong the inspection pump cycle
