The wind blows and blows
How did the strong wind become electricity?
The wind turbine is composed of head, swivel, tail and blade. The blades are used to receive wind power and convert it into electric energy through the nose; The tail wing keeps the blades facing the direction of the coming wind.
So as to obtain the maximum wind energy; Swivel can make the aircraft head rotate flexibly to realize the function of tail wing direction adjustment; The rotor of the head is a permanent magnet, and the stator winding cuts the magnetic line of force to generate electric energy.
Wind power generation is to use the wind to drive the windmill blades to rotate, and then increase the speed of rotation through the booster engine to promote the generator to generate electricity.
"Big windmill"
On November 16, at the construction site of No. 3 unit in Qianqing Wind Farm of Jilin Oilfield, the first section of the tower, weighing 84 tons, with a diameter of 5.2 meters and a height of 22 meters, was slowly lifted, and the first wind turbine of PetroChina was successfully lifted. This also marks that Jilin Oilfield has taken a new step from the traditional oil industry to the integrated development of new energy.
The project is PetroChina Jilin Oilfield
The project is under the responsibility of China Petroleum Engineering&Construction Corporation and entered the field construction stage in early August this year. Up to now, the foundation, cushion cap and other construction links have been completed, and the hoisting conditions have been met. Besides, the construction of other booster stations, high-voltage lines, communication systems and other supporting facilities is progressing as planned, and it is expected to be grid connected for power generation by the end of the year. At that time, Jilin Oilfield will make substantial progress in self consumption and clean replacement of electric power.
At present, according to the common vision of "creating and integrating the development of new energy industry, expanding the green and low-carbon economy, rebuilding the sunshine new industry of the oilfield, and creating a new Jilin oilfield model", Jilin Oilfield is accelerating the launch of efforts to promote the precise implementation of various projects and accelerate the progress, and strive to achieve green and low-carbon transformation and high-quality development as soon as possible.

Green "Power Bank" makes the scenery energy storage more "beautiful"
Walking into the work area of the Special Operation and Maintenance Department of PetroChina Daqing Oilfield Power Supply Company, there is an inconspicuous small yard. At the first sight, you can see a super "charging treasure", which is the wind and rain energy storage system platform independently produced by the Special Operation and Maintenance Department. Approaching the platform of the solar energy storage system, a power generation windmill with spinning wings "catching the wind" came into sight. Next to the power generation windmill was a photovoltaic panel with sparkling light "chasing the sun", which formed the core component of the platform of the solar energy storage system by contrasting with a row of neat white battery containers.
"The wind and solar energy storage system platform is like a super large capacity charging treasure. When the power consumption is low, it digests, accepts and stores the new energy generation capacity into the 'body'; when the power consumption is peak, it releases these electric energy into the grid to meet the needs of the work area." Zhang Qingnian, the leader of the low-voltage electrician team, said in a clear voice about this super "charging treasure".
The wind blows and the horse bursts, charging ahead. In the process of implementing the green and low-carbon transformation, the Special Operation and Maintenance Department has been exploring experience and building the first wind and rain energy storage simulation system of the oilfield. They use scrapped equipment and materials, independently produced wind and solar energy storage system platform, integrated wind power generation, solar energy storage, flywheel energy storage, wind and solar complementary control and other functions, which can be applied to oilfield power grid, oil pipeline network, oil wells and other remote video online monitoring fields in the future.
At present, the wind and solar energy storage system platform is in the trial stage, which can generate 5256 kilowatt hours of electricity throughout the year. It can independently supply office power, street lamps, garage doors and other power consumption in the work area of the Special Operation and Maintenance Department. "At the same time, the wind and solar energy storage system platform can also be used as an emergency power supply support. After the electricity is' full grid ', it can store 38 kilowatt hours of electricity to meet the power demand of the work area for more than 60 hours of operation." Zhang Qingnian continued to introduce.
Next, on the basis of the wind and solar energy storage system platform, the Special Operation and Maintenance Department will open up a unique production mode of "smart energy+environmental governance", focusing on the transformation of comprehensive energy application services and technological innovation. The electrochemical energy storage is applied to practical work. It can save the cost of power consumption, relieve the pressure of peak power consumption, and provide reliable power supply.
New energy development is speeding up again Fengcheng Oilfield
Fengcheng Oil Region of Xinjiang Oilfield is located in the Urho region of Karamay, which is a typical continental region. It is full of soil and wind map envoys. It is the king of power generation, and approves the great demand for Wangdu, boosting the development of new energy in Fengcheng again.
Since this year, Fengcheng Oilfield operation area has carried out single type wind and solar energy storage integrated clean well supply and grid connected optical power supply room in heavy oil and thin oil production stations. Power generation started on July 19, with an average daily power generation of 29 kWh and 872 kWh, and an accumulated power generation of 609 kWh and 1395.1 kWh.
At present, some rare oil low production and low efficiency single wells in the operation area of Fengcheng Oilfield use the intermittent mode, that is, let the pumping unit run when the liquid level in the wellbore is high, stop pumping when the liquid level in the wellbore is low or the liquid volume is low, and wait until the formation achievements are sufficient before production. This production mode can save production operation cost to the greatest extent and improve single well production efficiency.
In view of this, the technicians give consideration to the intermittent opening cycle, combine the production law of oil wells with the production law of photovoltaic power generation, and use the same characteristics of the production law of "photovoltaic power generation+pumping between oil wells" to formulate the production system of "solar power generation+opening day and closing night". When the light intensity at night is not enough, the production operation will be suspended. When the light intensity in the daytime is high and the power generation capacity is strong, the single well production will be started.
Some remote wells and side exploration wells without power supply in the future can adopt the off grid wind and solar storage power supply project to reduce the power supply cost or effectively use the power supply construction time, so as to achieve green oil production while competing for more oil.
