The Optimum Proposal Research of the Gas Well’s Flat Buckle Oil Pipe About the Size of the Gland

Gland can be effective to improve the air sealing of the flat buckle oil pipe, the size of the gland have great impact on the effect of the air sealing. But the optimal size of the flat buckle oil pipe is influence on the parameters of the pipe and the condition of underground. At present, it has not yet formed the optimum proposal. For this purpose, this paper establish the model of the stress-strain with the condition of underground and conclude the size of gland of gas well’s flat buckle oil pipe optimum proposal. The result of the research indicates that within certain limits, the smaller of the gland’s external diameter, the more thickness of the gland, the larger of the contact pressure, the better of the sealing property.
