对新疆油田易漏失井漏失特点进行了分析,介绍了以针对不同的漏失特点,采取对应的防漏堵漏方法,提高易漏层抗破能力;以及应用井壁稳定技术,提高井壁稳定性为主的易漏失井固井前井眼准备技术。通过应用该技术,易漏失井堵漏成功率100%;固井质量合格率100%、优良率85.5%。 Based on the analysis of the characteristics of the leakage of easily lost wells in Xinjiang Oilfield, the corresponding methods of preventing leakage and plugging are adopted to improve the anti-leakage ability of the leakage layer in view of the different characteristics of the leakage. The application of the technology of borehole stabilization improves the stability of the sidewall Based Well-Leak Well Cementing Wellbore Preparation Technology. Through the application of the technology, the successful rate of plugging in easily-lost wells is 100%; the qualified rate of cementing is 100% and the excellent and good rate is 85.5%.
