Technical Field
The invention relates to the technical field of coal bed gas development, in particular to a photovoltaic and gas complementary power generation direct-current drive oil pumping unit system.
Background
In the process of developing the coal bed gas, the construction of a power grid is one of necessary conditions, but due to the limitation of geographical conditions, the coal bed gas wells are mostly distributed between Chong mountain and no ready-made power transmission network is available, so that a production unit needs to wire by itself and then search a proper power supply point to access the commercial power, and the power supply mode has the following three disadvantages:
the early-stage wiring cost is high. Through the calculation, the current comprehensive wiring cost is 40 ten thousand yuan/kilometer of the high-voltage wire, 20 ten thousand yuan/kilometer of the low-voltage wire, 30 ten thousand yuan/kilometer on average, and the wiring cost of a single well is about 15 ten thousand yuan, which reaches about 6% of the total investment of a gas well. In addition, the wiring project is also restricted by factors such as geography and weather, and a certain time cost is generated.
The power supply point is difficult to guarantee. After the wires are laid, the power supply points cannot be found in time, so that power supply cannot be carried out. Some projects find a proper power supply point even two years after wiring, and the development progress is greatly slowed down.
May occupy arable land. Power transmission facilities often require arable land.
Therefore, a new power supply mode of the coal-bed gas well field needs to be developed urgently.
