摘　　要：油田开发过程中油水井出砂是很普遍的现象,恢复油水井正常生产、清除油水井的砂子是必不可少的技术措施。常规的冲砂方式不但无法达到需求,大量的冲砂液又可能污染地层,导致油井不能正常生产。研究应用了一种施工简单、工作量不大,又能解决地层漏失、降低水敏等问题的负压清砂方法,是清砂工艺的发展趋势。During the exploitation of oil field,sand production in oil and water wells is a very common phenomenon and it is essential technical measure to recover normal production and remove sand of oil and water wells. The conventional sand cleaning way not only can not achieve the requirement,quantities of sand washing fluid but also contaminates formation,resulting in oil well not to be normal production. A method of sand cleaning by negative pressure is studied on that is a simple operation,less workload,but also can solve problems of the formation loss,reducing water sensitivity,which is the development trend of sand cleaning process.
