Design and experiment research on sealing rubber tube of top packer of liner hanger

ZHANG Kuilin;GU Lei;Technology Management Department,SINOPEC;Research Institute of Petroleum Engineering,SINOPEC;  
Top packer of liner hanger for Ф244.5 mm casing was developed to solve the problem of oil, gas and water channeling caused by isolating failure in the top overlaying interval during liner cementing. Combination of rubber structure and anti-receding mechanism were adopted to improve seal reliability, and finite element method was used to compute the setting process of the packer and optimize structure. Then isolation and temperature property parameters of the top packer were researched and tested.Experiment shows that resistant pressure reaches 70 MPa under 150 ℃, and locking force is more than 1,500 kN. The field application shows the packer set successfully and isolated the leakage zone and high pressure gas reservoir, and the isolating problem of overlap interval was resolved.
