Abstract

A large-scale multi-functional fracturing fluid experimental system, which enters the foam generator through the chemical liquid and gas branches for mixing, and then enters three straight pipes with different pipe diameters to measure the influence of pipe diameters on the friction of the fracturing fluid, or enters the disc The tubes are used to measure friction, and the two ends of these four sets of tubes are connected with differential pressure sensors. When measuring friction, these four sets of tubes are equipped with valves at both ends. During the experiment, these sets of valves can be switched, and you can choose Open all the way, the multi-level window can observe the suspension state of the proppant in the fracturing fluid, and then enter the chemical liquid pump for circulation to measure the friction, or enter the outlet separator at the end of the experiment. The present invention is used to measure the gel fracturing liquid, clear water fracturing fluid, carbon dioxide foam fracturing fluid, or carbon dioxide dry fracturing fluid at different temperatures and pressures for research on rheological properties, friction properties, and sand-carrying performance. Suspension state in fracturing fluid.

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...
