Because horizontal segments of horizontal wells in Western Sichuan is long, it is hard to conduct casing running and it is not easy to make it be centered, which affects the displacement efficiency. Adoption of the liner hanging cementing method can greatly reduce the risk of casing blocked midway in horizontal well. After liner hanging, tie-back cementing can cement casing overlapping section in an even better fashion, which can play an important role in improving the cementing quality and reducing oil and gas channeling. The main technical requirements of this cementing manner and performance of cementing tools are a key link in well cementing. Successful field application experience of the technique can provide useful reference for horizontal well cementing in Western Sichuan.
