An experimental device and method for vibration and deformation of a production string in a shallow sea drilling high-yield gas well

Abstract

The invention relates to a vibration deformation experiment device and method of a production pipe string of a shallow sea drilling high-yield gas well. The device includes air compressor, buffer tank, pressure regulating valve, partition plate, pressure sensor, conduit, gas collector, computer, fixing device, cable, fixing plate, spherical radial inlet head, gas pressurization chamber, rock Chamber, rubber layer, one-way valve, gas cylinder, air pressure valve. The airflow generated by the air compressor is regulated by the buffer tank and the pressure regulating valve, and then passes through the one-way valve and enters the gas pressurization chamber, which has a rock chamber. Combination of air compressor, buffer tank, pressure regulating valve, check valve, gas storage bottle, and gas pressurization chamber to adjust the same air pressure as the gas collected in real time, and then collect the pressure sensor on the computer to vibrate when the air pressure passes through the catheter. Catheter deformation data. The invention has the advantages of safety and reliability, simple operation, accurate measurement data, simple operation, and can highly restore the gas recovery working state of the pipe string under real conditions.

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 ...
