Problems solved by technology

[0005] (1) Large size and heavy weight: the diesel engine drives the gearbox to drive the fracturing plunger pump through the transmission shaft, which is large in size and weight, limited in transportation, and low in power density
[0006] (2) Not environmentally friendly: Diesel engine-driven fracturing equipment will generate engine exhaust gas pollution and noise pollution during the operation of the well site. The noise exceeds 105dBA, which seriously affects the normal life of the surroun

Embodiment Construction

[0021] Such as figure 1 As shown, a fracturing pump power drive system includes a turbine engine 1, an exhaust system and a fracturing pump 3, one end of the turbine engine 1 is connected to the exhaust system, the other end of the turbine engine 1 is connected to the fracturing pump 3, and the fracturing pump 3 is connected to the other end of the turbine engine 1. The pump 3 is a fracturing pump 3 with its own reduction box 2 , and the turbine engine 1 is directly connected to the input end of the reduction box 2 on the fracturing pump 3 . The fracturing pump power drive system is driven by a turbine engine 1, and the turbine engine 1 can use 100% natural gas as fuel to replace diesel consumption in diesel engine driving, reducing fuel costs for customers. The turbine engine 1 itself has small size and light weight Advantages, greatly reducing the size and weight of the fracturing pump power drive system.

Abstract

The invention discloses a fracturing pump power driving system. The fracturing pump power driving system adopts a turbine engine for driving, the turbine engine can take natural gas as fuel 100%, andcan replace diesel consumption in diesel engine drive, the fuel cost of a customer is reduced, the turbine engine has the advantages of being small in size and small in weight, the size, the weight and the like of the fracturing pump power driving system are greatly reduced, the turbine engine is directly connected with the input end of a reducer casing of a fracturing pump, a transmission devicebetween the fracturing pump and the turbine engine is simplified, a transmission shaft or coupler is omitted, the whole length of the fracturing pump power driving system is greatly shortened, according to the technical scheme, a power source is the turbine engine, the transmission device is the reducer casing of the fracturing pump, an execution element is the fracturing pump, the structure is simple, and maintaining is convenient.

Description

technical field [0001] The invention relates to the technical field of oilfield operations, in particular to a fracturing pump power drive system. Background technique [0002] In oil and gas field fracturing operation sites around the world, there are two main driving methods for fracturing equipment: [0003] The first driving mode is driven by a diesel engine. The specific solution is that the diesel engine is connected to the gearbox to drive the fracturing plunger pump to work through the transmission shaft. That is to say, the power source is a diesel engine, the transmission device is a gearbox and drive shaft, and the actuator is a fracturing plunger pump. . [0004] This configuration mode has the following disadvantages: [0005] (1) Large size and heavy weight: The diesel engine drives the gearbox to drive the fracturing plunger pump through the drive shaft, which is large in size and weight, limited in transportation, and low in power density. [0006] (2) No...
