摘　　要：TY - 1高温堵水剂是由小分子有机聚合物交联而成的凝胶堵剂 ,性能优良 ,具有耐高温 ,抗高盐 ,成胶强度大 ,热稳定性好的特点。只要合理控制现场施工的注入压力 ,就可使堵剂沿高渗透带活塞式运移 ,在地层温度下形成凝胶体 ,从而有效的封堵高渗透性出水地层。现场试验了 6口井 ,均取得了明显的增油降水效果。TY 1 high temperature plugging agent is a kind of gelatinous plugging agent crosslinked by a small molecule organic polymer,and with good properties.High temperature resistance,high salinity resistance,high gel strength and good thermal stability are the characteristics of the plugging agent.In field application,the plugging agent can be piston like migrated along high permedbility zones by controlling the injection at a reasonable pressure and gelled under formation temperature.Therefore water producing zones of high permeability can be shut off effectively.Remarkable results of increasing oil and decreasing water have been given by 6 field applications.
