AI Technical Summary

Technical Problem

The existing tracer injection technology for fracturing is uneven when the fluid viscosity is high, the flow rate changes greatly or the tracer concentration is high, resulting in uneven distribution of tracer in the fracturing fluid.

Method used

An intelligent automatic tracer automatic injection device is designed, including two liquid storage tanks, mixing tanks, agitating components, heating components and protective components. The uniform mixing of tracer and fracturing fluid is achieved through the combination of gears, tooth rings and stirring leaves; the heating assembly is used to maintain liquid stability, and the protective assembly protects the injection tube to ensure uniform delivery.

Benefits of technology

The uniform mixing of tracer and fracturing fluid in complex fracturing environments is achieved, ensuring that the tracer is evenly distributed in the fracturing fluid, and the injection efficiency and effect are improved.

Abstract

The present invention relates to the technical field of oil and gas field exploitation, and discloses an intelligent self-controlled tracer automatic injection device for fracturing, comprising two liquid storage tanks, the bottoms of the two liquid storage tanks are provided with support assemblies, a mixing tank is installed on the middle top side of the support assembly, a stirring assembly is provided inside the mixing tank, a connecting valve is installed at the bottom of the mixing tank, an injection pipe is installed at the end of the connecting valve away from the mixing tank, an outer pipe is installed on the periphery of the injection pipe, a heating assembly is installed on one side of the outer pipe, and protection assemblies are provided on both left and right ends of the periphery of the injection pipe, and a generator is installed on the side of the support assembly close to the liquid storage tank. The stirring assembly and the regulating assembly can adapt to different viscosities, flow rates, and concentrations, the protection assembly can reduce the expansion deformation of the injection pipe during injection, and the heating assembly can avoid crystallization of the tracer and the fracturing fluid when conveying the tracer and the fracturing fluid.
