Embodiment Construction

[0029] The invention provides a fracturing fluid mixing system, which can improve the mixing efficiency of the fracturing fluid, shorten the mixing time, and thereby reduce the mixing energy consumption.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] Such as figure 1 As shown, the fracturing fluid mixing system provided by the embodiment of the present invention includes a suction pump 1, a mixer 2 and a mixing tank 3, which also includes:

[0032] A secondary mixer 5 arranged between the mixer 2...

Abstract

The invention provides a blending system of a fracturing fluid. The blending system comprises a suction pump, a mixer, a mixing tank, a secondary mixer which is arranged between the mixer and the nixing tank and is used for mixing the fracturing fluid again, and a parallel-connection water channel, wherein one end of the parallel-connection water channel is communicated with the suction pump, the parallel-connection water channel and a mixing water channel of the mixer are connected in parallel, and the other end of the parallel-connection water channel is communicated with the secondary mixer. The blending system provided by the invention has the advantages that the parallel water channel is additionally arranged and is connected with the mixing water channel in parallel, a base solution is capable of simultaneously entering two routes, namely the mixing water channel and the parallel-connection water channel, not all of the base solution enters the mixing water channel, a condition that the limitation on blending efficiency is caused by the relatively small flow of the mixing water channel is avoided, the blending time is shortened, the blending energy consumption is reduced, the fracturing fluid is formed through multi-time blending in a double-route manner, the mixing uniformity is improved, and the quality of the fracturing fluid is further optimized. The invention also provides a fracturing fluid blending technology suitable for the blending system of the fracturing fluid.

Description

technical field [0001] The invention relates to the technical field of oil / gas production equipment, more specifically, to a fracturing fluid mixing system, and the invention also relates to a fracturing fluid mixing process. Background technique [0002] During oil testing or production of oil and gas wells, the production of oil and gas wells will be low due to pollution near the wellbore (drilling, cementing, well washing and killing processes will cause pollution) or low original permeability of the formation. This problem can be solved by fracturing technology. [0003] Fracturing technology refers to a method of using liquid pressure to form cracks in oil and gas reservoirs in the process of oil or gas production. The specific operation is to use high-pressure and large-displacement pumps and use the principle of liquid pressure transmission. A liquid with a certain viscosity (that is, fracturing fluid) is injected into the reservoir at a pressure greater than the abs...
