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。 Using the theory of surfactant, we developed a kind of high efficient active agent - plugging agent that can remove and prevent the deposition of organic matter, and solved the problem of wax deposition and asphalt deposition in the vicinity of wellbore or wellbore , Resulting in the unblocking of the wellbore or the blockage in the formation near the wellbore, thus affecting the normal production of the well or the decline of the production of the well. Laboratory tests show that the agent is good for dissolving waxy asphalt and has good oil washing ability. In 1994, 12 wells were used on site, with an effective rate of 80%. The average single-well effective period was 58.1 days, with a total increase of 2378 tons of oil. The economic benefit was significant.
