Abstract

The operation of gas storage reservoir is characterized by alternating loads and cyclic reciprocation, which puts the tubular column in a complex stress state for a long time. At the same time, the corrosive environment downhole also threatens the service life of the tubing column, and it is of great significance to carry out the residual strength evaluation and residual strength prediction of the tubing column in gas storage reservoirs for the safe and smooth operation of the reservoirs. At present, the main object of casing safety evaluation for gas reservoir casing is casing column, and the content of injection and extraction tubing column is less reported. This paper proposes the safety evaluation method of gas storage reservoir injection and mining pipe column on the basis of SY/T 7370 and SY/T 7633, establishes the residual strength model and residual life prediction model of injection and mining pipe column based on the mechanical and wall thickness inspection data of the pipe column, specifies the internal pressure, external extrusion and tensile (compression) strength of the injection and mining pipe column and the safety inspection cycle of the pipe column, and explains the axial force law of the pipe column based on the six effects of the packer-column, which is important for the safe and smooth operation of gas storage reservoirs. It also illustrates the axial force law of the column according to the six effects of the packer-column, which provides methodological and technical support for the safety evaluation of gas storage reservoir injection and extraction columns. The model is applied to the injection and extraction tubular column of a gas reservoir well in an oil field.
