The present invention provides a gas storage injection-production string test method and a control device. The method comprises the steps of obtaining a first correction magnetic positioning curve on a static working condition and a second correction magnetic positioning curve on a dynamic working condition; according to the first and second correction magnetic positioning curves, obtaining the deformation amount of an injection-production string on the dynamic working condition; then correcting a preset injection-production string analysis software according to the deformation amount of an injection-production string, so that the measurement result of the injection-production string analysis software is more accurate, the accuracy of an injection-production string safety check result is improved, and the favorable conditions are provided for the long-term safe production of the gas storage.
Description
technical field [0001] The invention relates to a pipe string testing technology, in particular to a gas storage injection-production pipe string testing method and control equipment, belonging to the technical field of production testing. Background technique [0002] When the production condition of the injection-production well of the gas storage changes, it will directly cause the change of the temperature and pressure inside and outside the injection-production string, and the change of temperature and pressure will lead to the change of the stress and deformation of the injection-production string, which will further affect the To the safety of the injection-production string and the sealing effect of the packer. If the injection-production string is subjected to excessive stress due to changes in temperature and pressure, it may cause the injection-production string to break off and the packer to be unsealed, and even cause failure to pull out or other more serious ac...
