Abstract

The invention provides a foam loop rheometer, which comprises a carbon dioxide addition part, a reagent addition part, a pressure balance part, a test part, a cleaning recovery part, a temperature simulation part and a computer and data collection storage part. The foam loop rheometer has the advantages that: 1) large-flow, high-quality and high-accuracy fluid can be provided; 2) the use of CO2 is saved; 3) the rheometer has a closed-loop test loop in which the fluid to be measured can flow circularly, the fluid to be measured can be mixed fully in the flowing process, and each test point canbe tested repeatedly; 4) in the test process, any reagent can be added into the rheometer to change proportioning; 5) in the rheometer, an intelligent constant speed and constant pressure circulatingpump is used, the speed and pressure of the fluid provided by the pump are constant, the fluid does not have pulses, and the measuring accuracy is high; 6) after tests are finished, experimental pipelines can be cleaned by using supercritical CO2 fluid, and the reagents can be recovered; and 7) the pollution on environment is reduced.

Description

technical field [0001] The invention relates to a foam loop rheometer, which belongs to the technical field of chemical metering. Background technique [0002] The damage of fracturing fluids to the conductivity of reservoirs and propped fractures has attracted more and more attention. High-quality, low-damage, and low-cost fracturing fluids are the direction of research. Foam pressure fluids are the latest focus of attention. The use of foam fracturing fluid in foreign countries accounts for 30%-35% of the fracturing fluid system, and there is a rapid development trend. Domestic development is relatively backward due to the limitation of research methods and equipment conditions. Therefore, it is particularly important to provide advanced instruments capable of carrying out the above-mentioned research and experiments. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a foam loop rheomet...
