[0047] Example 2:

[0048] The method used in the fracturing fluid high-flow liquid distribution system, the method steps are as follows:

[0049] 1) Input the required fracturing fluid formula into the power and control system. The control system controls the start of the base fluid preparation system. The viscous material automatic supply device adds rubber powder according to the received signal, and the peripheral water is transferred through the large and efficient solid-liquid mixing device. The water in the tank is mixed with rubber powder to form a base liquid;

[0050] 2) The base fluid is input to the rapid viscosity increasing system, and under the control of the control system, the viscosity increasing device is activated to increase the viscosity;

[0051] 3) The control metering device on the base fluid preparation system collects the water inflow in real time, and the thickener automatic precision feeding device collects the added amount of rubber powder and feeds it ba...

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, and relates to a large-flow fracturing fluid dosing system and a dosing method. Background technique [0002] Hydraulic fracturing is an important technical measure for increasing the production of oil and gas wells and water injection wells. It is not only widely used in low-permeability oil and gas reservoirs, but also has achieved good results in the stimulation of medium and high-permeability oil and gas reservoirs. Hydraulic fracturing Generally, the high-viscosity liquid is injected into the well by using the surface high-pressure pump group at a displacement that greatly exceeds the absorption capacity of the formation, and high pressure is generated at the bottom of the well. When the pressure is greater than the in-situ stress near the well wall and the tensile strength of the formation rock, Fractures are generated in the bottom layer near the bottom of the well, and the ...
