摘要 填砾是第四系、上第三系松散地层成井工艺中的重要环节,为了确保所填滤料到位,填砾前泥浆替换达到要求是非常重要的,本文介绍了沉淀管换浆方法,同过滤器换浆方法进行了比较,沉淀管换浆方法比过滤器换浆方法替换泥浆效果更好,更有利于洗井工作及增大管井出水量。 Gravel-filling is an important process for well construction technology in Quatemary and Neozoic loose layer. In order to ensure gravel fill reach to the location, mud fluid displacement before gravel filling is very improtant. The mud fluid displacement method from blank casing slump is introduced in this paper and it is also compared with the mud fluid displacement method from screen assemble. The mud fluid displacement method from blank casing slump is more effective. And it also contributes flushing well and increases the flow quantity of a well.
