Description

Technical Field

[0001] This utility model relates to the field of fracturing fluid preparation technology, and in particular to a fracturing fluid mixing, preparation and delivery device. Background Technology

[0002] The essence of fracturing is to inject a liquid with a certain viscosity into the formation at high speed using a high-pressure pump set. When the injection speed is greater than the absorption speed of the formation, the formation will fracture or the original small gaps will open up to form larger cracks. As the liquid is continuously injected, the existing cracks extend inward. This liquid with a certain viscosity used for fracturing is called fracturing fluid. Fracturing fluid itself requires a liquid matrix with the addition of various additives and is classified according to the thickening method and degree of thickening.

[0003] Most existing fracturing fluid mixing and delivery systems consist of a single mixing tank and a conveying structure. During operation, materials are added and mixed in the mixing tank to prepare the fracturing fluid, which is then conveyed out by the conveying structure. However, fracturing fluids are mostly prepared on-site according to the operating environment. Different proportions and preparation methods can easily cause certain changes in the properties of the fracturing fluid. Therefore, the quality of the fracturing fluid output from the mixing tank is prone to fluctuations, which in turn affects the fracturing effect and leads to a decrease in the effectiveness of the fracturing fluid mixing and delivery system.

[0004] Therefore, in response to the problem that existing fracturing fluid mixing and delivery devices often require fracturing fluid to be prepared on-site according to the operating environment, and that different proportions and preparation methods can easily cause certain changes in the properties of the fracturing fluid, the quality of the fracturing fluid output from the mixing tank is prone to fluctuations, leading to a decrease in the effectiveness of the fracturing fluid mixing and delivery device, a fracturing fluid mixing and delivery device with a rapid mixing structure can be designed.

[0026] In use, firstly, the material is supplied to the rotating pipe 15 and the outlet 19 through the connecting pipe 16 and the feeding pipe 6 and discharged. At the same time, solid material is added through the first material pipe 8.

The fracturing fluid in the temporary retention pool 24 also contains a large amount of material, which can be further processed to meet the requirements as much as possible. Adjusting materials are added to the fracturing fluid, and the second motor 27 and the stirring rack 28 are used to stir and mix it. The completed fracturing fluid is discharged through the discharge pipe 29 for formal fracturing operation. This solves the problem that when existing fracturing fluid mixing and conveying devices are used, the fracturing fluid is mostly prepared on-site according to the use environment. Different proportions and preparation methods can easily cause certain changes in the properties of the fracturing fluid. Therefore, the quality of the fracturing fluid output from the mixing tank is prone to fluctuation, resulting in a decrease in the effectiveness of the fracturing fluid mixing and conveying device.
