SY/T 6638-2024 in English

Standard Revision Background and Technology Evolution

Compared with the 2012 version, this revised version SY/T 6638-2024 mainly reflects three major technical orientations: renewable energy integration (newly added geothermal energy utilization clause), energy efficiency level improvement (motor energy efficiency requirements are raised to Level 2 of GB30254-2013), system optimization (12 obsolete clauses are deleted and 8 advanced technology regulations are added). The standard introduces innovative requirements such as prefabricated buildings (8.4.6) and mixed transmission technology (6.3.8) for the first time.

Comparison of core energy-saving technology frameworks

Key points for energy efficiency control of key equipment

Analysis of new energy consumption calculation method

Appendix A introduces dynamic calculation formula:

$E=\sum_{i=1}^{n}(E_{i}\cdot k_{i})$

Among them, the standard coal conversion coefficient is in accordance with the requirements of Appendix B, the natural gas value is 1.1-1.33kgce/m³ (Table B.1), and the electricity equivalent value is 0.1229kgce/(kW·h) (Table B.2). Special attention should be paid to:

1. The gas injection and production periods need to be calculated separately (Article 6.1.5)
2. Energy-consuming working fluids are included in the statistical scope
3. The latest discount coefficient is adopted

Implementation suggestions

Design stage

1. Give priority to the gas-liquid mixed transmission process (Article 6.3.8) to reduce the energy consumption of the well site
2. The configuration rate of variable frequency air coolers should be ≥80% (Article 6.3.5)
3. The load rate of the heating furnace is controlled at 50-120% (Article 8.3.4)

Operation stage

1. Establish an energy consumption monitoring system (Article 4.3 measurement requirements)
2. Carry out simulation optimization regularly (Article 5.4)
3. Efficiency evaluation of the waste heat recovery system
