Problems solved by technology
[0005] The disadvantage of the prior art is that when the stirring device in the existing semi-trailer is actually stirring, the added materials are in a viscous state when the fracturing fluid is being stirred, and the proppant added in the fracturing fluid is generally They all use high hardness quartz sand, ceramsite, etc., but most of the existing stirring shafts and paddles are fixed. Under the impact of viscous liquid and high hardness proppant, not only is it easy to The blades are greatly worn, and they cannot be stirred evenly in the viscous liquid state, which affects the formation quality of the fracturing fluid

The invention discloses a petroleum fracturing fluid sand mixing adding device which comprises a base, a mixing tank, a proppant conveying mechanism and a stirring mechanism are arranged on the base, the proppant conveying mechanism is used for conveying a proppant to the stirring mechanism, and the stirring mechanism comprises a stirring barrel and a stirring assembly arranged in the stirring barrel. The stirring assembly comprises a center shaft and a plurality of stirring shafts connected to the center shaft, each stirring shaft is movably provided with a plurality of stirring blades, and when the center shaft is driven by the driving unit to rotate, the stirring blades can rotate. According to the petroleum fracturing fluid sand mixing adding device , when fracturing fluid materials are mixed, the stirring blades can be driven to rotate under the impact of a liquid mixture, the stirring efficiency in the viscous mixture can be improved, the impact of quartz sand on the stirring blades can be reduced, and on the premise that the stirring efficiency is improved, abrasion to the stirring blades is reduced, and the service life of the stirring device is prolonged.
Description
technical field [0001] The invention relates to the field of fracturing fluid technology, in particular to an adding device for petroleum fracturing fluid sand mixing. Background technique [0002] Fracturing fluid refers to a heterogeneous and unstable chemical system formed by various additives in a certain ratio. It is a working fluid used in fracturing oil and gas reservoirs. Its main function is to transmit the high pressure formed by ground equipment. Into the formation, the formation is broken to form fractures and the proppant is transported along the fractures. Water-based fracturing fluid is currently the most widely used fracturing fluid. Water-based fracturing fluid uses water as a solvent or dispersion medium, and adds thickened It is formulated with additives and additives. It mainly uses three kinds of water-soluble polymers as thickeners, namely vegetable gum, cellulose derivatives and synthetic polymers. These high molecular polymers swell into sols in water...
