摘要

In recent years, the gas storage well bolted out frequently everywhere. Those accidents usuallyrnresult in the failure of the pipe's junctions on the shaft collar. Sometimes even the whole tubrnbroke out from the ground. As a result, the natural gas leaks, gas storage well is abandoned, evenrncauses big fire, explosion. Considered casing, cement mantle and layer as elastic material,rnelasticity theory and thick-cylinder theory were adopted; casing-cement-mantle layer model wasrnbuilt in the paper. Basic dynamic parameters of layer, geometric and physical parameters ofrncement mantle, and geometric parameters of casing were analyzed. The major failure causes andrnmeasurements to control gas well accidents were suggested in the paper.
