摘　　要：针对传统的油井清砂方法易产生环境污染的现状,胜利采油厂对油田修井冲砂工艺进行了改进,通过改装设备;改进捞砂工艺等措施,自2000年1月至2001年11月,已经实施捞砂作业井417口,一次成功井373口,一次成功率为89.45%。工艺改进实施后,还节省了化学堵剂的使用;杜绝了油层污染;减轻了现场操作人员的劳动强度和冲砂事故发生率,初步实现了油田修井冲砂施工的清洁生产。In view of the fact that traditional sand-washing method of oil well will result in environmental pollution easily, the process of well repair and sand-washing have been upgraded in Shengli oil production plant. The methods of modifying equipment and improving the process of sand-picking have been adopted for 417 wells in Shengli oil production plant, with its successful application on 373 wells and success rate of 89.45%. Following the upgrade of the process, the chemical agent has been saved, pollution on oil layer has been avoided and labor intensity of operation staff and occurrence rate of sand-washing accident have been reduced to achieve the clean production on well repair and sand washing preliminarily in oilfield.
