Fracturing fluid mixing and sand mixing semitrailer

Abstract

The invention relates to a fracturing fluid and sand mixing semitrailer, and belongs to the field of fracturing devices for oil field work. The fracturing fluid and sand mixing semitrailer comprises a semitrailer body, a hydraulic system and an electrical control system. The hydraulic system comprises a hydraulic oil tank, at least one hydraulic pump and a hydraulic multi-way valve. An engine, the hydraulic system, the electrical control system, a lifting control chamber, a spiral conveyor, a clean water suction centrifugal pump, a fracturing fluid suction centrifugal pump, a stirring machine, a discharge centrifugal pump, a liquid adding pump, a dry powder adding device and a concentrated guanidine gum adding pump are integrated on the semitrailer body. The work steps of conducting glue solution mixing after fracturing liquid mixing is conducted and discharging the glue solution to a downward fracturing device can be conducted by operating the electrical control system to drive the hydraulic pump through an operator, and therefore work steps of oil field work are highly integrated, matched devices are reduced, workloads of working staff are reduced, and construction quality is ensured.

Description

technical field [0001] The invention relates to a fracturing fluid mixed sand mixing semi-trailer, which belongs to the field of fracturing equipment for oilfield operations. Background technique [0002] As the core equipment in the fracturing construction team, the sand mixer truck is widely used in the oil and gas field. The sand mixing semi-trailer is a special equipment that realizes sand mixing in proportion and can effectively supply different sand glue fluids to the fracturing equipment according to the requirements of the fracturing process. At present, the development direction of sand mixing equipment at home and abroad is large displacement and large sand volume, so 100bpm sand mixing equipment has become the mainstream product of conventional fracturing equipment, while the traditional sand mixing truck is equipped with a suction centrifugal pump. Inhaling the mixed fracturing guar gum fluid into the liquid addition tank requires a lot of supporting equipment, ...
