| 摘 要： | 介绍了近年来江汉油田在油井重复压裂研究方面所做的部分工作,及其对江汉油田油井重复压裂机理所取得的认识。针对江汉油区井深、油层渗透率低、层薄、地下油水分布复杂的地质特点,总结出了油井重复压裂的选井原则。对周16井、周181井的重复压裂改造现场试验取得一定的增油效果。对认识江汉油田老井重复改造工艺、提高老井原油采收率具有重要的指导意义。

| Abstract: | Part of the research on oil well re-fracturing was carried out in Jianghan Oilfield and as well as the recognition of re-fracturing mechanism in the oilfield were introduced.In allusion to the characteristics of exploration wells,low permeability and complex distribution of underground water in Jianghan Oilfield,the principle for well selection was summed up for well re-fracturing.It was used for field test in Wells Zhou 16 and 181 with certain oil increment.It is an effective guidance for fracture reconstruction and improving oil recovery rate in old wells of Jianghan Oilfield. |

| Keywords: | re-fracturing enhance oil recovery old well reconstruction Jianghan Oilfield |
