介绍聚丙烯酰胺凝胶解堵剂的配方、配方性能、施工工艺及在蒙古林油田的应用效果 ,该解堵剂能使粘度非常大的聚丙烯酰胺交联体迅速溶解成粘度接近于水的溶液 ,解除聚丙烯酰胺交联体因堵水作业对油层造成的损害和堵塞。在蒙古林油田现场应用 1 4井次 ,有效 1 2井次 ,取得了较好的解堵效果。 This paper introduces the formula, formulation performance, construction technology and application effect of polyacrylamide gel blocking agent in Mongolian Oilfield. The solution blocking agent can rapidly dissolve polyacrylamide crosslinked body with very high viscosity into water with viscosity close to that of water Solution, to lift the polyacrylamide cross-linked body due to plugging operations on the reservoir damage and blockage. In the field of Mongolian Oilfield, 14 wells were used and 12 wells were effective, which achieved good effect of plugging.
