Hydraulic fracturing system for driving a plunger pump with a turbine engine

A hydraulic fracturing system for driving a plunger pump with a turbine engine, comprising a fracturing equipment, a high-low pressure manifold, a blending equipment and a sand-mixing equipment;

• the blending equipment is used for blending fracturing base fluid in the hydraulic fracturing system, the sand-mixing equipment provides the fracturing base fluid and a fracturing proppant to the high-low pressure manifold;
• one end of the high-low pressure manifold is connected to the fracturing equipment through a connection pipeline, the other end of the high-low pressure manifold is connected to a wellhead;
• a turbine engine is used as the power source of the fracturing equipment, and the turbine engine is fueled by natural gas or diesel,
• wherein the fracturing equipment comprises one or more sets of turbine fracturing equipment,
• wherein the turbine fracturing equipment comprises a turbine engine, an exhaust system and a plunger pump, one end of the turbine engine is connected to the exhaust system, the other end of the turbine engine is connected to the plunger pump, the plunger pump is a plunger pump integrated with a reduction gearbox, the turbine engine is directly connected to an input end of the reduction gearbox integrated on the plunger pump,
• wherein an input speed of the reduction gearbox integrated on the plunger pump matches an output speed of the turbine engine, and an input torque of the reduction gearbox integrated on the plunger pump matches an output torque of the turbine engine.
