Oilfield energy-saving equipment suppliers remind you that with the increasing demand for energy conservation in society, the goal of peaking carbon emissions and achieving carbon neutrality is gradually entering the public's attention. Another major factor in promoting the creation of green oil and gas fields is energy conservation and emission reduction. Energy consumption is like an invisible claw, constantly emptying the earth and spraying mist into nature, destroying the originally pure and beautiful nature with smoke and rust. Saving resources is a fundamental national policy of China, so energy conservation and emission reduction are the mission that the petroleum industry cannot shirk. The main production processes such as drilling, oil extraction, oil and gas gathering and transportation, surface engineering, and petrochemicals are actively carrying out energy-saving and emission reduction work.
(1) The drilling rig has been equipped with an "energy-saving heart". The diesel engines commonly used on drilling rigs can be considered as "oil tigers" and "dirty tigers". To save energy, efforts must be made in the "recipe" of diesel engines. The diesel/natural gas dual fuel high-power and high-efficiency engine, which consumes more gas and drinks less oil, is known as the "energy-saving heart" of drilling rigs. In recent years, the recipe for drilling rig power has also added "oil to electricity", which means transforming the diesel engine that "drinks oil" into an electric motor that "consumes electricity". In recent years, the "oil to electricity" drilling rig has been used in oil fields. This type of drilling rig has fewer malfunctions and less pollution, which not only saves drilling costs but also reduces noise and vibration, which is beneficial to the health of drilling workers.
(2) The pumping unit is equipped with an "energy-saving brain" - the pumping unit frequency converter control cabinet. According to statistical data, the energy consumption of oil extraction accounts for about 56% of the total energy consumption of the oilfield, among which mechanical oil extraction, oilfield water injection, and heavy oil extraction are the three major energy consumers. For mechanical oil extraction, frequency conversion control technology is used to intelligently transform the pumping unit, and a "energy-saving brain" - a variable power energy-saving device is installed on the pumping unit. According to the changes in the load of the pumping unit's donkey head, a series of technical means such as soft start, automatic speed regulation, dynamic power adjustment, and energy-saving braking are used to timely deliver as much electricity as the motor needs, solving the problem of "a big horse pulling a small car", and also enabling the electrical energy generated during the downward stroke to be fed back to the power grid. In recent years, the electricity cost of the widely used "self variable power electric motors" in oil fields has been significantly reduced, and technological upgrades have tightly grasped the throat of the "electric tiger". Not only has it subdued high energy consumption, but it has also allowed it to obediently extract more crude oil from underground.
(3) Powerful water injection pump and high-efficiency energy-saving steam boiler. The electricity consumption of the water injection system accounts for about 30% of the total electricity consumption of the oilfield. Energy saving and emission reducing measures such as using a five plunger powerful water injection pump, improving water injection quality, and improving water injection technology can be adopted for water injection. During heavy oil extraction, a large amount of fuel is consumed to produce steam, and the energy-saving expert of the gas injection system is the high-efficiency and energy-saving steam boiler. It adopts new technologies such as high-temperature radiation coating, monitoring of excess air in flue gas, and recovery of waste heat from flue gas, effectively improving the combustion condition of the boiler and enhancing the thermal efficiency of steam production. In addition, using new technology nanomaterials to lay steam injection insulation pipelines can increase the utilization rate of gas injection heat energy by more than 20%.
(4) Energy saving during the flow of oil and gas. The traditional crude oil gathering and transportation process involves dual pipe water mixing and triple pipe heat tracing, which is complex and consumes high energy. Through research and development, the use of crude oil gathering and transportation at room temperature, also known as "cold transportation", is adopted to achieve energy-saving goals.
(5) The major surgery of 'Old Jian, New You'. In order to extract oil, a large and complex oil and gas network has been constructed on the surface of the oilfield, which includes engineering and link by link oil extraction, gathering, transportation, and export. Therefore, in order to save energy, it is necessary to cut through the ground engineering system and implement simplified measures of "closing, stopping, merging, turning, and reducing", that is, "shutting down old equipment requires equipment merging and turning, minimizing stations and shortening oil and gas pipelines".
