摘　　要：利用江苏油田有 ＣＯ_２气源井这一有利条件，根据气源井出气的状况．研究成功了管道输送ＣＯ_２工艺、液态ＣＯ_２注入工艺及防腐、返排等配套技术，并因地制宜，就近选择了近１０口井进行现场应用，获得较好的增油效果。管道输送ＣＯ_２单井吞吐工艺是一项适合复杂小断块油田提高原油采收率的三次采油技术，在江苏油田有较高的推广价值。There are CO_2 gas wells in Jiangsu oilfield. In order to use the CO_2 to enhance oil recovery,matching technique such as transporting CO_2 through pipeline,liquefied CO_2 injection,CO_2 corrosion control,CO_2 backflow,etc., was developed successfully. This technology was used in nearly 10 wells in the adjacent area, and better stimulation effect was achieved. The technology of huffing and puffing pipeline transported CO_2 in single well is a tertiary oil recovery technique suitable for improving the oil recovery of small complex fault block reservoir,it possesses higher popularization value in Jiangsu oilfield.
