Research and Application of Blocking Remover
-
摘要: 运用表面活性剂理论研制出了一种集解除和预防有机物沉积为一体的高效活性剂-解堵剂,较好地解决了蜡质、沥青沉积堵塞而带来的在井筒或井眼附近地带沉积,导致井筒不畅通或近井地带地层堵塞,从而影响油井正常生产或油井产量下降问题。室内试验表明该剂对蜡质沥青溶解性能好,洗油能力强。1994年现场应用12井次,有效率80%,平均单井有效期为58.1d,累计增油2378t,经济效益显著。Abstract: According to the theory of sufactant, we developed a bloking remover. Experiment shows that its dissolution on asphalt is good, capacity of washing oil strong, The problems of jamming in well bore and reseavoir near well have been solved. Applied it to the field 12 times in several well in 1994, effective ratio is 80%, average effective time 58.1d, accumulative oil increased by 3378t.
