Shallow sea well drilling high-yield gas well production tubular column vibration deformation experimental device and method

Abstract

The invention relates to a shallow sea well drilling high-yield gas well production tubular column vibration deformation experimental device and method. The device comprises an air compressor, a buffer tank, a pressure regulating valve, a splitter plate, a pressure sensor, a guide tube, a gas collector, a computer, a fixing device, a cable, a fixing plate, a spherical radial air inlet head, a gaspressurization chamber, a rock chamber, a rubber layer, a one-way valve, a gas storage bottle and an air pressure valve. The air flow generated by the air compressor enters the gas pressurization chamber after being regulated by the buffer tank and the pressure regulating valve through the one-way valve, and the rock chamber is formed in the gas pressurization chamber. The air compressor, the buffer tank, the pressure regulating valve, the one-way valve, the gas storage bottle and the gas pressurization chamber are combined to adjust the same air pressure with gas collected under the actual situation, and then data of the pressure sensor that the air pressure vibrates when passing the guide tube so that the guide tube deforms is collected on the computer. The shallow sea well drilling high-yield gas well production tubular column vibration deformation experimental device and method have the advantages that the device is safe and reliable, the operation is simple, measurement data is accurate, the operation is simple, and a gas production working state of a tubular column under the actual situation is reduced highly.

Description

technical field [0001] The invention relates to the technical fields of fluid mechanics and natural gas exploitation, and relates to a vibration deformation experiment device and method for a production string of a shallow sea drilling high-yield gas well. 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 deformation ...
