摘要
注水井经过长期注水后,井筒内和射孔处容易沉积一些脏物,导致注水压力升高,影响注水井的正常注水,因此,通过注水井洗井来解决井筒及地层内的脏物。利用高压水,清除注水井井筒、吸水层段的渗滤面及井底附近的污物,使吸水层段的渗滤面避免或减缓注入水水质的污染、堵塞和腐蚀,通过洗井可以解除或缓解井底近处已经受到的水质污染及堵塞,从而恢复地层吸水能力,确保注够水、注好水。随着注水井洗井技术的发展,现在洗井主要向环境保护,洗井质量,洗井成本等因素考虑洗井的方式,经过长期的摸索,活动洗井车洗井技术能够满足以上洗井的要求,成为日后洗井的主要方式。
water injection well after long-termwater flooding ng,wellbore and perforated deposited somestolen property,leading to increased injection pressure, the normal water injection wells. Therefore, through injection well well washing to solve wellbore and formation of stolen goods. Using high pressure water, removal of contaminants from water injection wells, water absorption layer of filtration surface and near the bottom of the well,sothat suction filtration surface layer of avoiding or slowing the injection water quality pollution and plugging and corrosion, the well washing can relieve near the bottom has been affected by the water pollution and congestion, thereby restoring formation water absorption capacity,to guarantee thenote enough water injection, water. With the development of water injection well washing technology, now wash well mainly to protect the environment and well washing quality,wash well cost and other factors considered well washing,after a long period of exploration and washing well well washing vehicle technology can meetthe above washing requirements becomefumre well washing main wash well.
