Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing:

[0013] Depend on Figure 1 to Figure 3 As shown, a fracturing fluid mixing device includes a skid-mounted base on which a motor 2, a hydraulic oil tank 3, a material storage tank 12, a fuel oil tank 10, a powder material tank, and a fuel oil tank 10 are respectively fixed to provide fuel. The engine 2 provides power for the device, and the power is transmitted to the hydraulic pump 5 through the transfer case 4. There are four hydraulic pumps in the whole device, and the hydraulic pump 5 drives the water inlet centrifugal pump 13, the liquid outlet centrifugal pump 14, and the thickening pump respectively. The centrifugal pump 15 and the feeding pump 16 finally transmit the mechanical energy of the engine to each pump through the hydraulic system.

[0014] Described powder tank comprises powder tank A601 and powder tank B602, and the inlet of described powder tank A601 and...

Abstract

A fracturing fluid blending device is mainly used for solving the problems that an existing onsite fracturing fluid continuous blending device is large in size, the time for viscosity to reach the useviscosity is long, and environmental pollution is caused due to the fact that a defoaming agent is added. The blending device is characterized in that a powder tank comprises a powder tank A (601) and a powder tank B (602), the inlet of the powder tank is connected with a powder tank header pipe (17), the outlet of the powder tank is connected with a storage tank (12), the outlet of the storage tank (12) is connected with a mixer (8), the feed inlet of the mixer (8) is connected with a water inlet pipe, the outlet of the mixer (8) is connected with a tackifying device (7), the outlet of the tackifying device (7) is connected with a liquid collecting tank (19), and the liquid collecting tank (19) is connected with a fracturing blender truck through a liquid discharge manifold (9); and a spraying device (18) is arranged in the liquid collecting tank (19). The fracturing fluid blending device is small in size, the tackifying time is shortened, the use of the defoaming agent is avoided, waste and environmental pollution are avoided, the fracturing period of a single well is shortened, and the fracturing efficiency is improved.

Description

technical field [0001] The invention relates to the field of oil fields, in particular to a fracturing fluid mixing device. Background technique [0002] Hydraulic fracturing technology has been developed for many years. With the advancement of fracturing technology, there are higher requirements for fracturing equipment. Not only the displacement and pressure requirements are constantly increasing, but also the continuous injection volume is also raised to a new height. At present, there are mainly two methods for continuous injection of fracturing fluid. The first method is the mixing of ordinary guar gum powder and water. This method is directly introduced into the relay tank for stirring and swelling after the mixing is completed. Generally, it needs Stir and swell for 10-15 minutes before the viscosity of the fracturing fluid can reach the operating viscosity. In order to ensure continuity, the time for the fracturing fluid in the relay tank to the outlet of the drainag...
