Abstract

A large multifunctional fracturing fluid experiment system is characterized in that a drug soup and a gas branch enter a foam generator and are mixed, the obtained mixture enters three straight pipes with different calibers, the influences of the calibers on the frictional resistance of the fracturing fluid are measured, or the soup enters a coil pipe in order to measure the frictional resistance, and two ends of each of the above four pipes are respectively connected with a differential pressure sensor; when the frictional resistance is measured, two ends of the four pipes are respectively provided with a valve; during experiment, the above valves can be switched, and one path can be selectively opened, the suspension state of a propping agent in the fracturing fluid can be observed through a multistage window, the obtained fracturing fluid enters a drug pump and is circulated in order to measure the frictional resistance; or the obtained fracturing fluid enters an outlet separator after the experiment. The system is used for measuring a jelly fracturing fluid, a clear water fracturing fluid and a carbon dioxide foam fracturing fluid, or can be used for researching the rheological characteristic, the frictional resistance and the sand carrying performance of a carbon dioxide dry fracturing fluid at different temperatures under different pressures, and can be used for observing the suspension state of the propping agent in the fracturing fluid through the multistage window.

Description

technical field [0001] The invention relates to an experimental system in the field of petroleum and natural gas development, in particular to a large-scale multifunctional fracturing fluid experimental system. Background technique [0002] Existing fracturing fluid evaluation instruments and equipment mainly include rheometers, friction meters and other equipment. Among them: the rheometer can be mainly used to measure the rheological properties of jelly fracturing fluid, mainly imported equipment is used to measure the jelly fracturing fluid in the rotor shear vessel. The friction meter can be used to measure the friction characteristics of gel fracturing fluid and clear water fracturing fluid. There are basically no instruments that can simultaneously measure the rheological and friction properties of fracturing fluids. [0003] In recent years, a new fracturing technology—carbon dioxide dry fracturing technology has gradually become popular, and more and more people ha...
