Embodiment 1

[0020] Example 1: Please refer to Figure 1-3 , an oil field water-based fracturing fluid safety configuration device, comprising a configuration tank 1, the top of the configuration tank 1 is provided with a feed pipe 2, the feed pipe 2 is convenient for inputting raw materials such as guar gum powder particles, and is convenient for subsequent water-based fracturing fluids. The preparation of fracturing fluid is convenient to use.

[0021] There is a crushing box 3 inside the configuration tank 1, and the crushing box 3 is set directly below the feed pipe 2. There are multiple groups of crushing rollers 4 inside the crushing box 3, and the outer wall of the crushing roller 4 is uniformly equipped with rolling teeth 5. 4. The crushing teeth 5 are interlocked and set, and the crushing rollers 4 in the crushing box 3 are rotated to crush and grind each other, so as to prevent the large particles from affecting the preparation of the subsequent water-based fracturing fluid and e...

Embodiment 2

[0029] Embodiment 2: On the basis of Embodiment 1, support legs 20 are provided at the bottom of the configuration tank 1, and a strengthening connecting plate 21 is provided between the supporting legs 20. The strengthening connecting plate 21 and the supporting legs 20 ensure the stability of the device, which is beneficial to the on-site configuration of water. The base fracturing fluid is convenient for normal oil extraction and easy to use.

[0030] The top of the dispensing tank 1 is provided with a transparent observation window 24, which is convenient for people to clearly observe the preparation situation inside the device, which is beneficial to use.

[0031] The shaker plate 6 is uniformly provided with a fold-shaped deceleration corrugator 22, which reduces the speed of falling of raw materials such as guar gum powder particles, ensures the uniform input of raw materials, facilitates the preparation of subsequent water-based fracturing fluids, and is beneficial to u...

Abstract

The invention discloses a safe preparation device for an oil field water-based fracturing fluid, and belongs to the field of oilfield chemistry. The device comprises a preparation tank, a feeding pipeis arranged at the top end of the preparation tank; a crushing box is arranged in the preparation tank; the inner wall of the preparation tank is hinged with one end of a shaking plate; a cam is arranged below the other end of the shaking plate; a water pumping pipe is arranged on a water tank, a spraying disc is arranged at the outlet end of the water pumping pipe; the output shaft of a stirringmotor is connected with a rotating shaft; a plurality of groups of stirring blades are mounted on the rotating shaft and arranged inside the preparation tank, four groups of measuring and sampling pipe orifices are formed in the preparation tank, an inclined guide plate is arranged at the bottom end of the preparation tank, a discharge pipe is arranged at the lowest end of the inclined guide plate, a heater is arranged inside the inclined guide plate, one end of a circulating pipe is connected with the discharge pipe, and the other end of the circulating pipe is connected with the lateral wall of the preparation tank. Large particles are prevented from influencing the subsequent preparation of the water-based fracturing fluid, the uniformity and effect of the water-based fracturing fluidare ensured, the preparation uniformity of the water-based fracturing fluid is ensured, and the subsequent use is facilitated.

Description

technical field [0001] The invention relates to the field of oilfield chemistry, in particular to a safety configuration device for oilfield water-based fracturing fluid. 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, fractures the formation to form fractures and transports proppant along the fractures. The main functions of fracturing fluid are: creating fractures and carrying sand. The fracturing fluid should be compatible with the formation rock and reservoir fluids and have minimal damage to proppant permeability. Its primary function is to create fractures and transport proppant along open fractures, so the viscosity of the fluid is critical. Successful fracturing operations require fluids to break quickl...
