摘　　要：对st-1型颗粒调剖剂进行了性能评价,结果表明st-1型颗粒调剖剂对大孔道岩心有很高的封堵强度和封堵能力,封堵率在97%以上,对渗透率大的岩心有好的封堵作用,能有效地降低大孔道岩心的渗透率。调剖剂颗粒具有良好的选择性和转向性,分流效果明显、岩心调剖后分流效果明显,在相对高渗透岩心形成有效封堵,高渗透岩心注入能力下降了94.62%,调剖后低渗透岩心注入能力提高了13.2倍。颗粒调剖剂抗剪切能力强、破碎率极低。The st-1 particle profile control agent for the Performance evaluation of test, the results show that particle profile control agent st-1 type of big hole core has high plugging strength and sealing ability, plugging rate is over 97%, the permeability of the core has good sealing effect, can effectively reduce the macroscopic throats core permeability.Particles of profile control agent has good selectivity and steering, shunt obviously, core shunt effect after profile control effect; in the relatively high permeability core form effective sealing, high permeability core injection capacity fell 94.62%, the injection profile control after low permeability core ability increased 13.2 times.Particle profile control agent shear resistance ability, broken rate is extremely low.
