Problems solved by technology

However, it has been found in field use that the sand mixing uniformity of this continuous sand mixing device still needs to be improved. Because it is based on the principle of liquid turbulent flow, it requires a very high rotation speed of the impeller, and because the impeller is in direct contact with the sand, the wear of the impeller is very serious. Serious, affecting the overall service life of the mixing device

Abstract

The invention belongs to the field of petroleum machinery, and in particular relates to a continuous hemispherical sand mixing device for fracturing, which can be applied to the development of unconventional oil and gas (such as shale gas, etc.). Continuous hemispherical sand mixing device for fracturing, including: base, sand mixing chamber, transmission box, upper end cover, main shaft, internal gear, cantilever shaft, transmission gear, characterized in that the base, sand mixing chamber, transmission box , and the upper end cover is fixedly connected in turn. Compared with the traditional open sand mixing device, the present invention realizes the continuous mixing and output of fracturing fluid and sand, and improves the sand mixing efficiency; compared with the Jereh continuous sand mixing device, the blade wear is greatly reduced, and the pressure The mixing of cracking liquid and sand is more uniform, and the overall sand mixing effect is significantly improved.

Description

technical field [0001] The invention belongs to the field of petroleum machinery, and in particular relates to a continuous hemispherical sand mixing device for fracturing, which can be applied to the development of unconventional oil and gas (such as shale gas, etc.). Background technique [0002] The development of shale gas puts forward higher requirements on the pressure and displacement of fracturing equipment. If you want to increase the displacement of sand mixing, the traditional open mixing device can only increase the volume of the sand mixing tank, but due to the limitation of the chassis, the method of increasing the displacement by increasing the volume of the sand mixing tank is already very popular in vehicle-mounted equipment. Difficult to achieve greater improvement. Jereh company put forward the concept of continuous sand mixing, adopting the method of "mixing and discharging immediately", which avoids the shortcomings of traditional sand mixing devices th...
