Mixing system

Abstract

The invention discloses a mixing system. The mixing system comprises a mixing module and an output module, the mixing module comprises a first liquid inlet header, an injection pump, a powder tank anda mixer, the first liquid inlet header is connected with the injection pump, the injection pump is connected with the mixer, and the powder tank provides powder for the mixer; the output module comprises a second liquid inlet header, a suction pump, a second flowmeter, a static mixer, a mixing tank and a liquid discharge manifold, and the second liquid inlet header, the section pump, the second flowmeter, the static mixer, the mixing tank and the liquid discharge manifold are sequentially connected; an outlet of the mixer of the mixing module is connected with an inlet of the suction pump ofthe output module through a valve, and the mixing module and the output module can be used respectively or used in combination as a complete set. The mixing system has the beneficial effects that thesecond liquid inlet header and the static mixer are arranged, mixing with large discharge capacity and high quality can be completed with low energy consumption; and the mixing system is flexible in disassembly and assembly.

Description

technical field [0001] The invention relates to the technical field of fracturing, in particular to a mixing system. Background technique [0002] Fracturing is the main measure to increase production in oil and gas fields. At present, domestic and foreign fracturing operations, especially shale gas fracturing construction sites, require a large amount of fracturing base fluid. At present, in the process of fracturing construction, the ready-to-mix and use fracturing fluid mixing trucks are widely used. However, with the increase of fracturing scale, due to various reasons such as chemicals, it is easy to cause air bubbles in the mixed fluid. As a result, the bubbles in the mixing equipment and downstream equipment increase, the amount of defoamer is increased, and the mixing effect is poor. At the same time, with the increase of the fracturing scale, the requirements for the displacement of the mixing vehicle and the viscosity of the dosing fluid are also increasing. highe...

At present, in the process of fracturing construction, the ready-to-mix and use fracturing fluid mixing trucks are widely used. However, with the increase of fracturing scale, due to various reasons such as chemicals, it is easy to cause air bubbles in the mixed fluid. As a result, the bubbles in the mixing equipment and downstream equipment increase, the amount of defoamer is increased, and the mixing effect is poor. At the same time, with the increase of the fracturing scale, the requirements for the displacement of the mixing vehicle and the viscosity of the dosing fluid are also increasing. higher

At present, based on the large-displacement mixing process, the mixing method used in most cases is to mix the concentrated liquid mixed with water or other base liquids first. This method is more efficient, but due to Different methods often have more effect differences, which is not ideal
