油田套管损坏一直困扰着我国浅层油田的开发,自70年代末吉林油田发现套管损坏井以来,吉林、大庆2个油田已有套损井近万口,损失高达数十亿元.仅大庆油田采油一厂萨中地区截止2000年8月31日就有1966口套管损坏井.1985年影响原油产量30×10~4t,经济损失不少于3亿元。 Damage to the casing of the oilfield has always plagued the development of shallow oilfields in our country. Since the casing damage was discovered in the Jilin Oilfield in the late 1970s, there are already 10,000 sets of casing damage and losses of billions of yuan in the two fields of Jilin and Daqing. There were 1966 casing damaged wells in the Sazhong area of ​​Daqing Oil Field No.1 Production Plant as of August 31, 2000. In 1985, the output of crude oil affected 30 × 10 ~ 4t and the economic loss was not less than 300 million yuan.
