Description
Technical Field
The utility model relates to an oil field operation technical field, concretely relates to fracturing pump power-driven system.
Background
On the fracturing operation site of the global oil and gas field, the driving modes of the fracturing equipment mainly comprise two modes:
the first driving mode is diesel engine driving, and the specific scheme is that the diesel engine is connected with a gearbox and drives a fracturing plunger pump to work through a transmission shaft. That is, the power source is a diesel engine, the transmission is a gearbox and a driveshaft, and the actuator is a frac plunger pump.
This configuration mode has the following disadvantages:
(1) large volume and heavy weight: the diesel engine drives the gearbox to drive the fracturing plunger pump through the transmission shaft, and the fracturing plunger pump is large in size, heavy in weight, limited in transportation and low in power density.
(2) And is not environment-friendly: in the well site operation process of the fracturing equipment driven by the diesel engine, engine exhaust pollution and noise pollution can be generated, the noise exceeds 105dBA, and the normal life of surrounding residents is seriously influenced.
(3) Uneconomic: the fracturing equipment driven by the diesel engine has the advantages of higher initial purchase cost, high unit power fuel consumption cost during the operation of the equipment and high daily maintenance cost of the engine and the gearbox.
The second driving mode is electrically driven fracturing, and the specific scheme is that a motor is connected with a transmission shaft or a coupling to drive a fracturing plunger pump to work. That is, the power source is an electric motor, the transmission is a drive shaft or coupling, and the actuator is a frac plunger pump.
Electrically driven fracturing by itself, while having many advantages, the powering of a fracturing well site is a prerequisite for electrically driven fracturing practices. Typically, the problem of powering a fracturing well site is not well solved. Or the power grid capacity of a well site is too small, and the whole fracturing unit is not driven; or the well site has no grid at all. Common electrically driven fracturing sites typically use generators to generate electricity, the most economical fuel for electricity generation is natural gas, but the use of natural gas requires the user to rent or purchase gas-fired power generating units. For a fractured well site without a power grid, the power of the gas-fired power generator set needs to reach at least 30MW, which is a significant investment for customers to purchase such a high-power gas-fired power generator set. More importantly, in the actual construction process, because the gas generator set is stopped due to faults, the whole electrically-driven fracturing unit can be paralyzed, the operation quality is seriously influenced, and even operation accidents can be caused.
Therefore, a power driving system of fracturing equipment with small volume, low investment cost and simpler structure is needed.
