中原油田已经持续开发三十多年,每个厂都有一些油井由于资源枯竭,没有开采价值导致关停。采油四厂关停井有上百口,这些关停井通常是空井筒。关停前,在关停井油层套管接箍的短节上用盲板将井口封死。停封井一般都是在油层套管节箍上安装一个短节,用盲板将短节上部焊接盲死。
Zhongyuan Oilfield has been continuously developed for more than 30 years, and some oil wells in each plant have been shut down due to depletion of resources without any exploitation value. There are hundreds of well shutdowns in the fourth oil production plant. These shutdowns are usually empty wellbores. Before shutting down, stop the wellhead with a blind plate on the short section of the shut-down well casing coupling. Suspension wells are generally installed in the casing section of the oil casing to install a short section, the blind with the blind will be welded to death the upper section.
