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.
Description
technical field [0001] The invention relates to the technical fields of fluid mechanics and natural gas exploitation, and relates to an experimental device and an experimental method for the vibration deformation of an inclined and curved gas well production string. Background technique [0002] The production string of a high-yield gas well is a channel for high-speed gas circulation. Due to storage supply, flow and pressure changes, gas flow excitation of high-yield gas wells, frequent well switching operations, and under the action of dynamic load, the vibration of the string is an extremely important research content. [0003] In the process of traditional oil and gas exploitation, the gas pipeline will be deformed due to the gas flow rate in the pipe, which will have a certain impact on oil and gas exploitation. [0004] In the process of oil and gas exploitation, the invention measures and controls the deformation of the conduit to a certain extent, and displays the de...
