摘要
近年来,随着CO2三次采油技术在江苏油田推广使用,CO2腐蚀造成油套管变形、错断等现象时有发生,通过对CO2井控、打捞、找漏和套管回接等技术的研究,形成了CO2井修井特色配套工艺技术系列,这些技术已经现场应用49井次,成功率94%,具有良好的推广应用前景.
Abstract
In recent years,with the application of CO2 tertiary oil recovery technology in Jiangsu Oilfield,the phenomena of casing deformation and wrong breakage caused by CO2 corrosion have often occurred.Through the research of CO2 well control,fishing,leakage finding and casing tieback and other technologies,a series of CO2 well workover characteristics supporting technology has been formed,and these technologies have been applied in 49 wells on site with a success rate of 94%,which has good prospects for popularization and application.
