The application of ENN power gas turbines in the field of oil and gas fields

After nearly ten years of technology accumulation, ENN Power has introduced gas turbine products of 100kW, 300kW and 2MW power levels to the market. In the past two years, ENN Power has actively explored the application of gas turbines in different scenarios from multiple dimensions such as market, technology, and policy, and signed nearly 50 contracts and industry construction projects in many fields such as industry, commerce, oil and gas extraction, and medium and low calorific value fuel utilization, with an average comprehensive energy efficiency of more than 80% of the system, reducing customer energy costs by more than 20% and reducing carbon dioxide emissions by more than 20%.

In particularoil and gas field fieldThere is a large amount of distributed heat and electricity demand in all production links of drilling, mining, gathering and transportation, and pipeline transportation, and often encounters the problem of insufficient power in remote areas or the need for power isolation mode operation, as well as how to collect and utilize wellhead associated gas more economically and environmentally friendly. ENN Power's pan-energy solution based on gas turbines has fully demonstrated its excellent performance in cost reduction, efficiency reduction, emission reduction and carbon reduction, and gradually played an important role in the low-carbon development of the oil and gas field.

Applications of gas turbines in the field of oil and gas fields

Oil and gas exploitation

China's oilfields produce tens of thousands of tons of crude oil per year, and their heavy oil reserves account for a certain proportion. There are a large number of steam injection stations in the field of heavy oilfields, with an average hourly steam demand of about 50 tons per station. At the same time, the cost of purchasing electricity is relatively high.

ENN Power provides gas turbine-based energy gathering, transportation and supply solutions:

●The use of oilfield associated gas as fuel not only prevents air discharge and causes environmental pollution; but also reduces costs

●Use the waste heat of gas turbine flue gas to generate high-pressure steam injection to meet the needs of heavy oil extraction

●Replacing the original boiler, meeting environmental requirements (NOx emission < 25ppmv)

● Combined heat and power generation to improve the comprehensive energy utilization efficiency of the heat recovery system

Use cases <<

A cogeneration project of an oil production plant in Liaohe Oilfield

Due to the needs of oil production technology, a large number of steam injection boilers are currently in service in a Liaohe oilfield. The oilfield uses a gas direct combustion steam injection boiler to inject steam into the underground oil production pipeline network for oil recovery. The gas boiler has low efficiency, pollutant emissions exceed the standard, and does not meet environmental protection requirements, so ENN Power provides it with an E2100 gas turbine + waste heat steam injection boiler combination scheme to replace the original gas boiler and provide steam for the oil station.

b) Reduce carbon emissions by 3655t/year

Oil and gas gathering and transportation

From the wellhead to the metering station → to the transfer station → to the joint station, there is a large amount of heat demand in the entire oil and gas gathering and transportation link. At the same time, it is also the largest associated gas consumption equipment in the field of oil and gas field, and the oilfield needs to solve the urgent need to reduce the consumption of associated gas, reduce electrical energy, and improve energy efficiency.

ENN Power provides gas turbine-based energy gathering, transportation and supply solutions:

●Using the associated gas in the oilfield as fuel, the chemical energy of the associated gas is converted into high-grade electricity, and then the waste heat of the flue gas is converted into low-grade hot water to achieve energy stepped utilization

●Associated gas turns waste into treasure, which not only reduces energy costs, but also reduces emissions

●The gas turbine combined heat and power system is used to replace the water jacket furnace system in the oil transfer station to heat up the oil and meet the hot water demand in the station; at the same time, it meets the electricity demand in the station

● The emission concentration of nitrogen oxides in gas turbines < 25ppm, which is environmentally friendly

●The flue gas temperature of the water inlet furnace is < 650°C, which slows down corrosion and prolongs the service life

●Equipped with a skid-mounted explosion-proof noise reduction box, which greatly improves the safety and stability of the whole system

Cogeneration project of an oil production plant in Shengli Oilfield

The oil transfer station under the oil production plant has a large output, stable petroleum associated gas, and a large demand for electricity and heat. With the increase of the country's environmental governance in the Bohai Rim and the Yellow River Basin, the traditional production process no longer meets the environmental protection requirements, and the original water jacket furnace and other equipment of the Shengli Oilfield Oil Transfer Station are facing comprehensive transformation due to low efficiency and excessive NOx emissions.
