边远零散注水井连续洗井车的研制,可解决固定式洗井流程存在的管网投资大、洗井能耗高、注水系统压力波动大、影响注水系统效率、洗井液来水对污水处理主流程的冲击大、洗井过程不便于控制井口返出水量等问题。由于采用了较先进的洗井污水处理工艺,使处理装置结构紧凑,处理效果好,只需一台车即可完成注水井的连续洗井作业。本文详细地介绍了活动洗井技术所要解决的主要问题、工艺流程、性能特点、技术参数和矿场应用情况。

The new developed continuous well cleanout track for marginal water injection wells can solve the following problems :high cost of pipe net of well cleanout flowsheat ,high energy exhause ,high pressure fluctuation of water injection system ,effect of water injection efficiency , strong impact of water cleanout fluid to the processing flowsheet of polluted water. Having used the advanced well clean – out processing technology ,the construction of the processing instrument is lightened , and get good result . Only one track can complete the continuous well cleanout operation. This paper introduces the solved problems , process flowsheet , characters , technical ,parameters and application in site.
