Fracturing construction device for unconventional oil and gas development

Abstract

The fracturing construction device comprises a barrel body, a sealing cover and a discharging assembly, a feeding opening for feeding materials into the barrel body is formed in the top of the sealing cover, a liquid injection assembly communicated with the interior of the barrel body is fixed to the outer side face of the barrel body, and an annular support capable of rotating in the circumferential direction is arranged on the inner wall of the upper end of the barrel body; a stirring assembly is fixed to the center of the annular support, a plurality of horizontally-arranged supporting plates are evenly distributed on the inner wall of the annular support in the circumferential direction, a material mixing assembly coaxial with the barrel is fixed to the inner ends of the supporting plates, and the material mixing assembly conveys materials at the bottom of the barrel to the upper portion of the barrel and discharges the materials into the barrel again. According to the sand mixing device, the annular support, the supporting plate, the material mixing assembly and the liquid injection assembly are used in cooperation, the annular support rotates, the material mixing assembly conveys sand at the bottom of the barrel body to the upper portion of the barrel body and discharges the sand into the barrel body again, and therefore the purpose that the sand in the barrel body is turned up and down is achieved, and the sand and mixed liquid are fully mixed.

Description

technical field [0001] The invention relates to the technical field of oil and gas development, in particular to a fracturing construction device for unconventional oil and gas development. Background technique [0002] Fracturing refers to a method of using hydraulic action to form cracks in oil and gas layers in the process of oil and gas development. The mixing tank is stirred evenly to form a fracturing fluid, which is delivered to the fracturing vehicle at a certain pressure. [0003] In the existing sand mixing device structure for fracturing construction, the upper end of the tank is opened and a coaxial annular plate is provided. The annular plate and the tank are fixedly connected by several connecting rods, and the inner bearing of the annular plate is connected to the coaxial The upper part of the outer periphery of the standpipe, the upper end of the outer periphery of the standpipe is fixedly installed with a coaxial ring gear, the left side of the top side of ...

AI Technical Summary

Problems solved by technology

Although this scheme improves the mixing efficiency of the sand material at the bottom of the sand mixing tank and the mixed liquid, and facilitates the rapid mixing of the sand material near the vertical stirring rod with the mixed liquid, but the sand material at the bottom of the tank will produce a certain amount of silt during mixing. These silted sand particles cannot be well mixed with the mixed liquid, causing the wear on the bottom of the sand mixing tank to still exist, and insufficient mixing of the sand material, resulting in longer mixing time, affecting the efficiency of sand material mixing, and unable to meet actual needs
