7.4 Power supply and distribution
7.4.1 Oil fields with a crude oil production capacity greater than 30x101/a should have an independent power supply. If conditions do not permit, a single power supply with dual circuits can be used. Oil fields far away from the regional power system should use other power sources. If necessary, a self-contained power station can also be built, but it should be demonstrated separately.
7.4.2 The capacity of substations at all levels in the oil field, the total load when the comprehensive water content is 50%, and the cross-section of the transmission line should be determined according to the power load when the comprehensive water content of the oil field is 70%. Industrial and civil power supply should be provided separately
7.4.3 According to the requirements for power supply reliability, oil field power is also divided into three levels: the classification of loads should comply with the provisions of "Design Regulations for Transformer and Distribution of Oil Fields and Long-distance Crude Oil Pipelines" SYJ33.X uses grid machine water
