摘　　要：本文通过对各类洗井管柱的分析研究后认为,要保证洗井液不进入地层达到洗井时保护油层的目的,可以通过走封隔器绕过地层返出地面,设计洗井管柱可避免洗井过程中洗井液进入地层。The analysis on different well washing pipe strings are carried out in this paper. It concludes that going through the packer to bypass the formation back out of the ground can prevent washing fluid from entering the reservoir. Therefore well washing pipe strings can be used to avoid washing liquid into the ground during well washing.
