EN 1918-5:2016 (E) DIN EN 1918-5:2016-11 4 1 Scope This European Standard covers the functional recommendations for the design, construction,
29、 testing, commissioning, operation, maintenance and abandonment of the surface facilities for underground gas storage (UGS), between the wellhead and the connection to the gas grid. It specifies practices which are safe and environmentally acceptable. For necessary subsurface facilities for undergro
30、und storage, the relevant part of EN 1918-1 to EN 1918-4 applies. In this context, “gas“ is any hydrocarbon fuel: which is in a gaseous state at a temperature of 15 C and under a pressure of 0,1 MPa (this includes natural gas, compressed natural gas (CNG) and liquefied petroleum gas (LPG). The store
31、d product is also named fluid); which meets specific quality requirements in order to maintain underground storage integrity, performance, environmental compatibility and fulfils contractual requirements. This European Standard specifies common basic principles for underground gas storage facilities
32、. Users of this European Standard should be aware that more detailed standards and/or codes of practice exist. A non-exhaustive list of relevant standards can be found in Annex A. This European Standard is intended to be applied in association with these national standards and/or codes of practice a
33、nd does not replace them. In the event of conflicts in terms of more restrictive requirements in the national legislation/regulation with the requirements of this European Standard, the national legislation/regulation takes precedence as illustrated in CEN/TR 13737 (all parts). NOTE CEN/TR 13737 (al
34、l parts) contains: clarification of relevant legislation/regulations applicable in a country; if appropriate, more restrictive national requirements; national contact point for the latest information. This European Standard is not intended to be applied retrospectively to existing facilities. 2 Norm

38、1 General The main equipment that may be required for both the withdrawal and the injection operations of gas storage facility is described below. Where no specific mention of LPG or natural gas is made, the following statements refer to both. 3.2 Underground gas storage 3.2.1 Overview and functiona
39、lity of underground gas storage EN 1918 covers storage of natural gas, Compressed Natural Gas (CNG) and Liquefied Petroleum Gas (LPG). Because of the relevance of underground gas storage of CNG the major part of this introduction is related to the storage of natural gas. The underground gas storage
40、(UGS) is an efficient proven common technology and is in use since 1915. UGS became an essential indispensable link in the gas supply chain for adjusting supply to meet short-term and seasonal changes in demand. Natural gas produced from oil and gas fields is increasingly being used to supply energy
41、 requirements. As the gas supply from these fields does not match with the variable market demand, natural gas is injected into subsurface storage reservoirs when market demand falls below the level of gas delivery or if there is an economic incentive for injection. Gas is withdrawn from storage fac
42、ilities to supplement the supply if demand exceeds that supply or withdrawal is economically attractive. The primary function of UGS is to ensure that supply is adjusted for peak and seasonal demand. Apart from this, the storage facilities can provide stand-by reserves in case of interruption of the
43、 planned supply. Increasingly UGS is applied for commercial storage services. Thus, in summary underground gas storage facilities can be used for: security of supply; providing flexibilities; balancing of seasonal demand variabilities; structuring of gas supply; provision of balancing energy for the
44、 optimization of transport grids; trading and arbitrage purpose; stand-by provisions and strategic reserves; structuring renewable energy sources power to gas; storage of associated gas as service for production optimization and resultant environmental conservation.

45、2016-11 6 3.2.2 Types of UGS For storage of natural gas, several types of underground gas storage facilities can be used which differ by storage formation and storage mechanism (see Figure 1): pore storage: storage in aquifers; storage in former gas fields; storage in former oil fields. caverns: sto

47、lt caverns For LPG storage, only salt or rock caverns can be applied. The UGS type applied is dependent on the geological conditions and prerequisites as well as on the designed capacity layout. EN 1918-5:2016 (E) DIN EN 1918-5:2016-11 7 3.2.3 General characterization of UGS UGS are naturally or art
48、ificially developed reservoirs respectively artificially developed caverns in subsurface geological formations used for the storage of natural gas (or LPG). A UGS consists of all subsurface and surface facilities required for the storage and for the withdrawal and injection of natural gas (or LPG).
49、Several subsurface storage reservoirs or caverns may be connected to one or several common surface facilities. The suitability of subsurface geological formations have to be investigated individually for each location, in order to operate the storage facilities in an efficient, safe and environmentally compatible manner. In order to construct a storage facility, wells are used to establish a controlled connection
