Abstract
In this paper, the difficulties and treating methods of cementing in gas medium are introduced, such as casingand U pipe effect. The formulation of cement slurry is optimized that can be used to carry out cementing in gas medium.The application in cementing of (?)244.5 mm casing in well YL1 shows that the high quality percent rate of cementing jobis 69.2%, which indicates that in gas medium, not only the cementing job term can be reduced, but also the cementing jobquality can be improved sharply.
