研究开发一种新型双液复合型聚合物油井堵水剂 .它兼有聚氨酯胶和环氧树脂胶的优点 .考察该堵水剂的性能 ,并进行模拟试验 .结果表明 ,堵水剂的甲、乙组分混合后 ,反应速度快 (数秒即反应并初凝 ) ,转向性能好 ,承压强度高 (反向承压 >1 0 MPa) ,封堵浅 (封堵半径 0 .2 m) ,封堵效率高 (每米厚度平均堵水剂用量 30 kg) ,易解堵 .适用于单层堵水、封窜、压裂层段堵水、薄隔层封堵、 5m以上厚油层封堵等 .已经完成了 5口井现场试验 ,封堵有效率达 1 0 0 % ,施工成功率 1 0 0 % ,共增油 1 4340 t,降水 62 730 m3.
Research and development of a new type of double-liquid composite polymer well plugging agent.It combines the advantages of polyurethane glue and epoxy resin.Check the performance of the plugging agent, and the simulation test.The results show that the plugging agent A , The second component, the reaction speed (a few seconds that is, the reaction and initial setting), steering performance, high bearing strength (reverse pressure> 10MPa), blocking shallow (blocking radius 0 .2 m) , Blocking high efficiency (average thickness of 30 meters water blocking agent dosage), easy to plug.Applicable to single-layer plugging, sealing channeling, plugging section plugging, thin barrier plugging, 5m thick oil seal Etc. The field test of 5 wells has been completed with an effective closure rate of 100% and a construction success rate of 100%, with a total increase of 14,340 tons of oil and a precipitation of 62,730 m3.
