Device for supplying power to pumping unit and heating oil pipeline by using petroleum associated gas

Abstract

The invention provides a device for supplying power to a pumping unit and heating an oil pipeline by using petroleum associated gas. The device includes a petroleum-fired boiler gas generator set. A voltage stabilization device is arranged in the access pipeline of the petroleum associated gas. The output end of the voltage stabilization device is connected with a heater. The output pipeline of the heater is connected with a desulfurizer. The output pipeline of the desulfurizer is connected with the intake pipeline of the gas generator set. The power output end of the gas generator set is connected with the pumping unit through a power control cabinet. The tail gas of the gas generator set is introduced into a first heat exchanger. The outlet pipe and the return pipe of the water tank of the gas generator set are connected with a second heat exchanger. Hot water in the first heat exchanger and the second heat exchanger is communicated and introduced into a petroleum-fired boiler. According to the invention, a large amount of electricity can be saved; an pumping unit can save more than 520,000 degrees of electricity each year, and the economic benefits are huge; desulfurization treatment and recombustion of the petroleum associated gas reduce a large amount of harmful gas emissions; and the device has very excellent environmental effects and social benefits.

Description

technical field [0001] The invention relates to the field of oil pumping unit power supply and oil pipeline heating device field, in particular to a device that utilizes petroleum associated gas to supply power to the pumping unit and heat the oil pipeline. Background technique [0002] At present, the pumping units in the oil field are all driven by electricity. The power of each pumping unit is 60-70 kilowatts, and the annual power consumption is more than 520,000 degrees. The associated gas is burned in vain and pollutes the environment. In addition, the oil extracted from the oil well needs to be heated by boilers to reduce the consistency and increase the fluidity. Although these boilers consume part of the oil-associated gas, the oil-associated gas has not been treated in the early stage, and the boilers burn directly to pollute the environment. If the oil associated gas can be used to drive the pumping unit and then burned after environmental protection treatment, it...
