Description

Technical field [0001] The invention relates to a fracturing fluid mixer in oil and gas development fracturing construction equipment, and in particular provides a fracturing construction device for oil and gas development. Background technique [0002] At present, oil and gas development needs to increase production in order to improve the recovery rate. Fracturing is one of the main technical means. During the fracturing process, a specified proportion of sand, water, cementing agent, chemical dry powder, etc. needs to be mixed. , The mixing equipment is mixed, and then injected into the bottom of the well under pressure by a pump truck. Generally, the fracturing fluid mixing system used on site uses a jet mixer or a jet dry powder adding device to complete the fracturing fluid mixing. The basic physical model can be Described by Bernoulli equation, the area of ​​the throat pipe decreases, the flow velocity increases, and a partial negative pressure is formed. The additive is s...

Problems solved by technology

[0002] At present, in order to improve the recovery rate of oil and gas development, reservoirs need to be stimulated and stimulated. Fracturing construction is one of the main technical means. , liquid mixing equipment for mixing, and then pressurized into the bottom of the well by a pump truck. Generally, the fracturing fluid mixing system used in the field uses a jet mixer or a jet dry powder adding device to complete the fracturing fluid mixing. The basic physical model can be Described by Bernoulli's equation, the area of ​​the throat decreases, the flow rate increases, and a local negative pressure is formed. The additive is sucked into the jet mixer and mixed with the working fluid. After mixing, it is discharged. The liquid flow rate, viscosity, and additive fluidity of the ejector vary greatly. The quality requirements of the mixed liquid are mainly met by adjusting the liquid flow rate and reducing the mixing speed, but it cannot be adjusted in real time to provide the fracturing fluid needed for fracturing operations in a timely manner.
