不压井修井作业技术适应欢西油田大环境发展的需要,对于油气井而言它可以保护和维持地层的原始产能,减少酸化、压裂等增产措施的次数。对于水井而言,它不需要停注放压,缩短施工周期,节省压井液费用、减少压井液对油层的损害,保护环境。辽河油田锦州采油厂自2010年以来开始从事油气水井不压井带压作业施工,技术趋于成熟,此项技术应用前景非常广阔。
Well-drilling workover technology meets the needs of the development of the environment in the Huaxi Oilfield. For oil and gas wells, it can protect and maintain the original production capacity of strata and reduce the number of stimulation measures such as acidification and fracturing. For wells, it does not need to stop pouring pressure, shorten the construction period, save the cost of killing fluid, reduce the killing fluid reservoir damage, and protect the environment. Since 2010, Jinzhou Oil Production Plant in Liaohe Oilfield has been engaged in the construction of oil and gas wells with no pressure and pressure, and the technology tends to be mature. The prospect of this technology is very broad.
