3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply.
3.1
gas gathering and transportation system in gas field
A process system within a gas field that extracts, collects, regulates pressure, separates, meters, and transports gas well products.
3.2
economical operation for gas gathering and transportation system in gas field
The operation of the gas field gathering and transportation system in an efficient, low-consumption state achieved through scientific management, optimized configuration, and technical improvements, while meeting process requirements and ensuring safety and environmental protection.
4 General Requirements
4.1 Outdated equipment and processes prohibited by the state shall not be used. The energy efficiency of newly added energy-using equipment shall reach the energy-saving level, and preference shall be given to energy-using equipment whose efficiency reaches the advanced level.
4.2 The economical operation of the gas field gathering and transportation system shall comply with relevant safety and environmental protection regulations.
4.3 When the gas field gathering and transportation system does not meet the economical operation indicators, an analysis shall be conducted, an adjustment or transformation plan shall be formulated and implemented, and the results shall be tested and evaluated.
4.4 The gas field gathering and transportation system should adopt technologies such as downhole choking, utilization of natural gas pressure energy, recovery and utilization of waste heat energy, and utilization of renewable energy sources like solar energy, wind energy, and geothermal energy.
5 Management Requirements
