Fracturing pump transmission system and fracturing truck

Abstract

The invention relates to the technical field of fracturing vehicles, and discloses a fracturing pump transmission system and a fracturing vehicle. The fracturing pump transmission system includes one or more engines, multiple oil pumps and multiple motors, wherein: when there is one engine, the engine is used to drive multiple oil pumps; when there are multiple engines, each engine is used to drive at least An oil pump; each oil pump is connected to at least one motor; the plurality of motors are used to drive the fracturing pump. Compared with the prior art, implementing the fracturing pump transmission system of the present invention can effectively expand the selection range of relevant components of the transmission system, realize multiple matching methods, effectively reduce the cost of relevant components, and effectively improve reliability at the same time , It is also convenient to realize the forward and reverse rotation of the fracturing pump. The fracturing truck of the present invention is equipped with the above-mentioned fracturing pump transmission system, so the manufacturing cost and production difficulty of the fracturing truck can be effectively reduced, and the operation efficiency and maintainability can be effectively improved at the same time.

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
