Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the following detailed description of the embodiments of the present utility model will be given with reference to the accompanying drawings, but the described embodiments of the present utility model are some, but not all embodiments of the present utility model.

As shown in fig. 1 to 3, a water-based fracturing fluid stirring apparatus includes: the agitator 1, its lateral wall intercommunication is equipped with the inlet pipe 11 of a level setting, the height of inlet pipe 11 is less than the liquid level of agitator 1 during operation, coaxial wear to be equipped with a spiral pushing rod 2 in the inlet pipe 11, it is connected in the main shaft of a motor 21, the rear end face of inlet pipe 11 is located to motor 21, the rear end top intercommunication of inlet pipe 11 is equipped with the feeding pipe 12 of a vertical state, its upper end opening is higher than the top of agitator 1, in order to avoid liquid to spill over, feeding pipe 12 is equipped with along the piston 3 of axis direction removal setting.

When the fracturing fluid is produced, auxiliary agents which are required to be added, particularly bentonite, a treating agent and drill cuttings, are put into the fracturing fluid through the upper end of a feeding pipe 12, and then the auxiliary agents are sent into a stirring barrel 1 by a spiral pushing rod 2 under the driving action of a motor 21, so that the auxiliary agents with lighter textures are directly immersed into the fluid, so that the auxiliary agents are prevented from floating on the surface of the fluid, and are prevented from being thrown around during stirring; the piston 3 can push the auxiliary agent in the feeding pipe 12 downwards, and can squeeze the liquid permeated into the feeding pipe 12 back into the stirring barrel 1.

Preferably, the feeding pipe 11 is spaced from the bottom of the stirring tank 1 by a predetermined distance so as to avoid the deposition of the light auxiliary agent and the weight auxiliary agent on the bottom of the stirring tank 1 after mixing.

Preferably, as shown in fig. 2 to 4, a partition board 4 is arranged at the position, corresponding to the connection position with the feeding pipe 11, of the inner wall of the stirring barrel 1, the partition board 4 comprises a rubber gasket 41, a plurality of lips 411 are arranged on the side wall, facing the inside of the stirring barrel 1, of the rubber gasket 41, when the rubber gasket 41 is in a natural state, the lips 411 are in a closed state, the spiral pushing rod 2 is used for pressing auxiliary agents in the feeding pipe 11 during feeding, the auxiliary agents push the lips 411 under the action of the pressure and then enter the stirring barrel 1, when the spiral pushing rod 2 stops running, the lips 411 are automatically closed again, so that the liquid amount flowing into the feeding pipe 11 at the initial stage of stirring is reduced, because the fracturing liquid has a certain consistency after being stirred for a period of time, and the fracturing liquid is not easy to enter the feeding pipe 11.

Preferably, as shown in fig. 1 and 2, a hopper 13 is arranged at the top of the feeding pipe 12 so as to facilitate rapid pouring.
