Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard was proposed by the Ministry of Land and Resources of the People's Republic of China.
This standard is under the jurisdiction of the National Land Resources Standards Technical Committee.
This standard was drafted. Oil and Gas Professional Office of the Mineral Resources Reserve Evaluation Center of the Ministry of Land and Resources, China National Offshore Oil Corporation
the company.
The main drafters of this standard. Chen Yongwu, Zhu Weilin, Li Mao, Shen Zhanghong, Zhou Wei, Chi Shugen, Lin Jincheng, Liu Chuncheng, Mi Lijun, Han Zheng,
Sun Bingyi, Shen Yuling, Jiang Ping, Zhao Chunming.
This standard is interpreted by the Ministry of Land and Resources of the People's Republic of China.
This standard is applicable from GB/T 19492 and DZ/T 0217, which are not inconsistent with this standard. Involving water depth
The sea area larger than 300m is mainly based on this standard.
Offshore oil and gas reserves calculation specification
1 Scope
This standard specifies the rules for the calculation and evaluation of offshore oil and gas reserves.
This standard is applicable to the reserves of crude oil, condensate and natural gas in offshore oil (gas) reservoirs (fields) from seawater high tide line to water depth of 300m.
Calculation and evaluation. The calculation of reserves of non-hydrocarbon gas reservoirs (fields) and oil (gas) reservoirs (fields) with biomass can be used as reference.

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Petroleum petroleume
A naturally occurring mixture of gas-phase, liquid-phase hydrocarbons and containing small amounts of impurities. This standard of petroleum refers to liquid hydrocarbons
Quality, the general term for crude oil and condensate.
3.2
Crude oil
Originally found in underground reservoirs, under normal pressure and temperature after harvesting to the ground, unprocessed, degassed liquid or semi-solid
The part of the body of oil.
3.3
Condensate condensate
Gaseous hydrocarbons under formation conditions, which are precipitated from the gas phase as the temperature and pressure decrease during the production to the surface.
A liquid mixture consisting of pentane and the above heavy hydrocarbon components can generally be recovered via a surface separator or a dedicated unit.
3.4
Natural gas gas
Naturally occurring hydrocarbons and non-hydrocarbon gases, as well as mixtures of various elements, in a gaseous state under formation conditions, or dissolved in oil or water
Medium is only in a gaseous state under standard ground conditions. Natural gas in this standard refers to gas reservoir gas, oil and gas reservoirs, condensate gas reservoir dry gas and reservoir dissolved gas.
The general term.
