Experimental device and experimental method for vibration deformation of oblique bending gas well production tubular column

Abstract

The invention relates to an experimental device and experimental method for vibration deformation of an oblique bending gas well production tubular column. The experimental device comprises a piston air compressor, a control valve, a pressure gauge, a guide tube, an adapter, an inner tube, a fixing plate, an outer tube, an outer tube fixture, telescopic support rods, sliding wheels, a sliding slot, pressure sensors, a cable, a computer and a fixing bracket, wherein the fixing bracket is composed of the telescopic supports, the sliding wheels and the sliding slot, and arc-shaped bending tube required to be simulated by the experiment can be adjusted through changing the length of the telescopic support rods and the position between two sliding wheels. The piston air compressor generates a high-pressure gas, the high-pressure gas flows through the inner tube to cause vibration, the same pressure as the gas collected in the actual condition is adjusted through the combination of the control valve and the pressure gauge, and then data of the pressure sensors when the air pressure passes through the inner tube and enables the inner tube to deform is collected on the computer. The experimental device has the advantages that the device is safe and reliable, the operation is simple, the measurement data is accurate, and the gas production working state of the bending tubular column inthe high-pressure gas well is highly reproduced.
