针对聚丙烯酰胺铬冻胶（或凝胶）系列堵调剂堵水调剖对非目的层造成伤害的现象，研制了ＣＨＹ解堵剂，该解堵剂是采用对油层无任何伤害的无机物添加一定的催化剂配制而成的。它能使粘度非常大的聚合物凝胶迅速溶解成粘度接近于水的溶液，该解堵技术具有解除堵塞能力强，施工工艺简单、方便的特点。经在蒙古林油田应用表明，有效率 ８５． ７％，平均单井增油 ６６０ｔ。
Aiming at the phenomenon that polyacrylamide chrome gel (or gel) series plugging agent is used to plug water and profile the damage to non-target layer, a CHY plugging agent is developed. The plugging agent is prepared by adding inorganic substances without any harm to the oil layer A certain amount of catalyst formulated. It can quickly dissolve very viscous polymer gel into a solution with viscosity close to that of water. The anti-blocking technology has the advantages of strong unblocking ability, simple and convenient construction technique. The application of the Mongolian oil field shows that the efficiency of 85. 7%, the average single-well oil 660t.
