[0002] While producing natural gas, oil and gas field enterprises also have a great demand for natural gas use, and the total energy consumption shows a rigid upward trend. In the production process, due to the changeable working environment, different parameters of energy-consuming equipment, and different energy consumption per unit, a lot of unnecessary energy consumption will be generated, which will reduce the production efficiency of oil and gas field enterprises, increase costs, and fail to effectively save energy and reduce consumption. Therefore, it is necessary to establish an energy management and control system for oil and gas field enterprises to help them save energy and reduce consumption.

[0003] For example, the “Energy Management and Control System for Oil Fields and Energy Consumption Control Method for Oil Fields” with application number 202110893640.X discloses an energy management and control system for oil fields and an energy consumption control method for oil fields. The energy management and control system includes: an energy consumption monitoring module, an alarm and warning module, an energy efficiency evaluation module, an energy efficiency optimization module, etc., wherein the energy consumption monitoring module collects the real-time energy consumption data of the energy-consuming equipment, and transmits the calculated energy consumption unit consumption index to the energy efficiency evaluation module for energy efficiency evaluation and analysis; the energy efficiency evaluation module automatically divides the energy-consuming equipment into high-efficiency areas, potential areas and inefficient areas, and transmits the energy-consuming object data of the screened out inefficient areas to the energy efficiency optimization module for energy efficiency optimization and adjustment.

[0004] In the above-mentioned automatic zoning evaluation process of energy-consuming equipment, it is necessary to combine indicators such as energy consumption plan and annual surplus level to monitor the total energy consumption and energy consumption intensity by unit and subsystem from different time dimensions, and conduct global macro-control of the total energy consumption. Therefore, its zoning assessment is often based on plans and manually formulated standards, lacking comparison between the energy consumption data of the energy-consuming equipment being tested, and cannot accurately reflect the actual working conditions of the energy-consuming equipment, and cannot meet the best energy efficiency optimization adjustment.

The above modules are respectively connected to the energy comprehensive management and control module. The monitoring unit and the early warning unit are determined by the physical type of energy extraction in the oil and gas field. The key energy-consuming equipment involved in different oil and gas fields is different. Taking the gas field as an example, the construction of the energy management and control digital platform must first meet the construction unit's energy consumption statistics and analysis of its subordinate units, especially the energy performance parameter monitoring and early warning of the key energy-consuming equipment of each basic energy-consuming unit. Typical key energy-consuming equipment are selected as basic unit model components of equipment: compressors, heating furnaces, air compressors, boilers, and pump groups.

[0045] The embodiment of the present invention provides an oil and gas field energy management and energy saving optimization method, taking a fuel-driven compressor as an example, Figure 2 As shown, the following steps are included:

[0046] S1. Set up a fuel-driven compressor monitoring unit and an early warning unit, determine the monitoring target data as the first-stage intake temperature, the second-stage intake temperature, the load rate, and the power cylinder jacket water temperature, and set the energy consumption benchmark value according to the on-site working conditions, and upload it to the early warning unit for retention;

[0047] S2. Energy meters are installed on fuel-driven compressors to enable them to have long-distance data transmission function and be connected to the energy integrated management and control platform to obtain equipment operation data with the same accuracy as the preset energy consumption benchmark value, including effective energy utilization, energy supply, and energy loss;

[0048] S3. When the above energy consumption parameters exceed the set reference value, the early warning unit issues an early warning, and the on-site personnel adjust and process the monitoring target data and observe whether the early warning is eliminated;

[0049] S4. If the warning is not eliminated, the energy consumption data and monitoring target data are uploaded to the energy saving and scheduling module in the energy comprehensive management and control platform of the operation area (treatment plant). The technical personnel will adjust and process it and observe whether the warning is eliminated;

[0050] S5.

The secondary unit will issue a monitoring commission to the monitoring unit. The monitoring unit will conduct on-site monitoring and evaluation, find out the causes, and form a rectification technical report to be submitted to the secondary unit and the equipment user unit.

[0051] S6. Equipment users shall decide whether to make rectifications on their own or report to the secondary unit for special rectifications based on the rectification costs. If necessary, a special rectification project at the oilfield company level shall be formed.

[0052] S7. The collected effective energy utilization, supply energy, and loss energy of the fuel-driven compressor are uploaded to the energy statistical analysis module, and the effective energy utilization, supply energy, and loss energy of three fuel-driven compressors of the same type in the time interval of 30 days are obtained, and the fuel-driven compressor energy consumption data are generated respectively. Then, the energy utilization efficiency formula is used to calculate the energy utilization efficiency of the three oil and gas field compressors of the same type, and η1, η2, and η3 are obtained. The average value is calculated by summing and compared with the energy utilization efficiency η of the fuel-driven compressor under test. The calculation formula is as follows:

The three time intervals are distinguished by ΔT1, ΔT2, and ΔT3 respectively to obtain the compressor energy consumption data. Then, the energy efficiency formula is used to calculate the energy efficiency of the fuel-driven compressor in the three time periods, and the average value is summed up and compared with the energy efficiency of the fuel-driven compressor under test.
