Hydraulic fracturing system for driving plunger pump by using turbine engine

Abstract

The invention discloses a hydraulic fracturing system for driving a plunger pump by using a turbine engine. The fracturing system comprises a fracturing device, a high-low pressure pipe joint, a mixing device, a sand blender and the like, a power source of the fracturing device is the turbine engine, fuel of the turbine engine is natural gas or diesel, the plunger pump is driven by the turbine engine, the problems of existing diesel driving and electromotor driving are solved, fuel supply of the turbine engine adopting a dual-fuel system is diverse and is not limited, especially, the cost is more saved when the natural gas serves as the fuel. The gas source supply modes of the natural gas are diverse in the whole hydraulic fracturing system, requirements for more clients can be better met,the whole fracturing device is arranged on a straight line in the direction of power transmission, the whole gravity center of the fracturing device is better lowered, and the stability and safety ofthe operation and transferring states of the fracturing device are improved.

Description

technical field [0001] The invention relates to the technical field of fracturing in oil and gas fields, in particular to a hydraulic fracturing system using a turbine engine to drive a plunger pump. Background technique [0002] Hydraulic fracturing has been used for decades to stimulate oil and gas wells. In this method, a plunger pump is used to pump fluid into the wellbore under high pressure, and then the fluid is squeezed into the formation to open the fracture, and water, other liquids and fracturing proppant are also injected into the fracture. After the fracturing is completed , the fracturing base fluid is returned to the surface, the fracturing proppant remains in the fracture to prevent the fracture from closing, and a large amount of oil and gas enter the wellbore through the fracture to be mined. [0003] In oil and gas field fracturing operation sites around the world, there are two main driving modes for plunger pumps: [0004] The first is that the diesel ...
