Abstract

The invention belongs to the field of carbon dioxide dynamic storage of oil and gas fields, and particularly relates to a carbon dioxide dynamic storage capacity well test measuring device. The carbondioxide dynamic storage capacity well test measuring device comprises an injection well test device and at least one observation well test device; the injection well test device comprises a sleeve, and further comprises an oil pipe, a cable passing packer, an adjusting oil pipe and a cable type underground intelligent switch which are sequentially arranged in the sleeve from a well mouth to the underground; and a storage type pressure gauge is integrated at the tail part of a shell of the cable type underground intelligent switch. According to the carbon dioxide dynamic storage capacity welltest measuring device, real-time dynamic pressure and temperature accurate monitoring of a CO2 injection well and a related observation well for one year is achieved, double backups are achieved through a direct-reading type pressure gauge, data are uploaded to a cloud server in real time, the data can be downloaded, browsed and inquired at a terminal, a pressure / temperature curve report can be output, and professional logging engineers can accurately analyze, research and economically evaluate CO2 dynamic sealing.

Description

technical field [0001] The invention belongs to the field of carbon dioxide dynamic sequestration in oil and gas fields, and in particular relates to a carbon dioxide dynamic sequestration capacity test well test measuring device. Background technique [0002] Concentrate the CO produced in industrial production 2 After liquefaction, it is transported to the oil and gas well mining area, and injected into the formation to realize CO 2 storage, which can reduce CO 2 emissions; at the same time, it has been proved that CO 2 It has good viscosity-reducing and dissolving effects on low-permeability reservoirs, and can increase production and generate income in low-permeability reservoirs. Currently in CO 2 The implementation of dynamic storage projects is relatively extensive, due to CO 2 Special high temperature and high pressure corrosive environment, domestic CO 2 The dynamic storage effect of injection cannot be accurately analyzed and studied and economically evaluate...
