Fracturing pump transmission system and fracturing truck

Abstract

The invention relates to the technical field of fracturing trucks and discloses a fracturing pump transmission system and a fracturing truck. The fracturing pump transmission system comprises one or more engines, multiple oil pumps and multiple motors, wherein when the system only uses one engine, the engine is used for driving multiple oil pumps, and when the system uses multiple engines, each engine is used for driving at least one oil pump. Each oil pump is connected to at least one motor. Multiple motors are used for driving a fracturing pump. Compared with the prior art, the fracturing pump transmission system can effectively expand a type selection range of transmission system related parts, various matching modes can be achieved, the cost of the related parts can be effectively reduced, meanwhile the reliability can be effectively improved, and forward and reverse rotation of the fracturing pump is further facilitated. The fracturing truck is provided with the fracturing pump transmission system, so that the manufacture cost and the production difficulty of the fracturing truck can be effectively reduced, and meanwhile the operation efficiency and maintainability can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of fracturing vehicles, in particular to a fracturing pump transmission system and a fracturing vehicle. Background technique [0002] Fracturing operation is one of the important means to transform oil and gas reservoirs. For low permeability oil and gas wells, it is generally necessary to rely on fracturing operations to achieve the purpose of stabilizing and increasing production. The fracturing vehicle is the main equipment for fracturing construction. Its function is to inject high-pressure and large-volume fracturing fluid into the formation, press the formation apart, and squeeze support materials (such as fracturing sand) into the cracks to strengthen the formation. Permeability, increase oil and gas mobility, enhance oil and gas recovery. [0003] At present, common fracturing vehicles adopt the transmission scheme of "diesel engine-hydraulic torque converter-transmission shaft-fracturing pump". F...

Problems solved by technology

[0004] In the above transmission scheme, due to the need to select a diesel engine that meets the maximum power, when the power exceeds a certain level (such as 1500KW), the required cost will rise rapidly and the selection of the model will be difficult, which will also result in the selection range of the matching torque converter and other components. Narrow, high price; Another factor that makes the selection of the above-mentioned transmission scheme difficult and the cost is high is that in the world, the technical maturity and industrial chain perfection of the components and parts related to fracturing operations in various countries are quite different. The diesel engine, hydraulic torque converter or transmission shaft of the above-mentioned transmission scheme need to be purchased from certain countries or regions, which will result in high cost of fracturing vehicles using this transmission scheme, and is limited by the cycle and supply of imported parts

[0005] In addition, the safety redundancy (reliability) of the above-mentioned transmission scheme is low. Once any one of the diesel engine, hydraulic torque converter and transmission shaft fails, the fracturing operation will be stopped. Since the fracturing operation site is generally located in a remote In addition, these parts are expensive and difficult to prepare in one go. Even in countries with relatively mature fracturing technology, it will take a long time to resume fracturing operations
