| Abstract:Liner hanger is a device for liner hanging and connecting with upper casing, which is important in liner cementing. Along with increasing liner cementing operation, various structures of liner hanger are used. Annular plug, too high displacement pressure and advanced setting often occur in field liner hanger operation. The paper introduces and analyzes liner hanger about its structure, performance characteristics, advantages and disadvantages, summarizes the prevention and treatment measures for the accidents easily occurred in the field application. |
