Scope
GB/T 8423.1-2018 is the English-translated version of 石油天然气工业术语 第1部分：勘探开发.
GB/T 8423.1-2018 is Part 1 of the Chinese national terminology of the petroleum and natural gas industries, and covers exploration and development. It defines terms in oil and gas geology, oil and gas field development, production engineering and the oilfield chemical agents used for oil recovery.
The vocabulary opens with general terms such as oil and gas exploration, development and production, petroleum, natural gas, coalbed methane, tight oil and tight sandstone gas, then moves through petroleum geology and comprehensive exploration, reservoir description, reservoir physics, development evaluation and enhanced oil recovery, and ends with completion, injection and production processes, downhole operations and production increase measures, followed by an index.
Other areas of the natural gas industry can use it as a reference. It was issued on 28 December 2018 and has applied since 1 July 2019.

Foreword
GB/T 8423 "oil and gas industry terminology" is divided into six parts.
--- Part 1. Exploration and development;
--- Part 2. Engineering Technology;
--- Part 3. Oil and gas ground engineering;
--- Part 4. Oil and gas measurement and analysis;
--- Part 5. Equipment and materials;
--- Part 6. Safety, environmental protection and energy saving.
This part is the first part of GB/T 8423.
This part is drafted in accordance with the rules given in GB/T 1.1-2009.
1 Scope
This part of GB/T 8423 defines oil and gas geology, oil and gas field development, oil and gas production engineering and oilfield chemical agents for oil recovery. Domain terms and definitions.
This section applies to oil and gas geology and exploration, oil and gas reservoir engineering, oil production engineering, gas production engineering and oilfield chemical agents, etc.
Other areas of the natural gas industry can be used as reference.
2 General basis
2.1 Oil and gas exploration
Geological surveys, geophysical exploration, drilling and other related activities to find oil and gas reserves.
2.2 Oil and gas development
Relevant activities such as evaluation, development and construction, and enhanced oil recovery for mining underground oil and gas resources.
2.3 Oil and gas production
The process of extracting crude oil and natural gas from the formation to the ground.
2.4 Petroleum
A mixture of liquids dominated by hydrocarbons in a subterranean formation.
2.5 Natural gas
A mixture of combustible gas and non-hydrocarbon gas that is dominated by gaseous hydrocarbons in a subterranean formation.
2.6 Coalbed methane
Coal bed gas
The coal seam (angular layer) is not transported out, and the gas in the coal seam and its surrounding rock is adsorbed and released.
2.7 Tight oil
Dense sandstones with a permeability of less than or equal to 0.1 x 10^-3µm2 (air permeability less than 1 x 10^-3µm2) Oil in reservoirs such as dense carbonates; single wells generally have no natural capacity or natural capacity below the lower limit of industrial oil flow, but under certain economic conditions and Industrial oil production can be obtained under technical measures.
2.8 Tight sandstone gas
For sandstone gas-bearing layers with a permeability of less than or equal to 0.1 x 10^-3µm2, the single well generally has no natural production capacity or natural productivity. The lower limit of industrial gas flow, but industrial gas production can be obtained under certain economic conditions and technical measures.
