Description

technical field

The utility model relates to the technical field of performance testing of underwater wellbore outsourcing foam, in particular to a performance testing and evaluation device for compressible foam materials.

Background technique

Due to the influence of water depth, the temperature of the seabed and shallow formations is low, while the temperature of the reservoir fluid is relatively high. In the early hours of oil and gas well testing and production, the annulus of each layer of casing will be sealed due to the flow of oil and gas in the wellbore The temperature of the fluid in the space increases significantly.

At present, most of the deepwater wellbore temperature and pressure measurements use on-site measurement points and theoretical predictions.
