中国新增石油和天然气探明地质储量特征

Characteristics of Incremental Proven Oil and Natural Gas Geological Reserves in China

为进一步掌握中国石油和天然气探明地质储量增长趋势,分析了2010—2019年中国新增石油和天然气探明地质储量分布和变化特征。结果表明:2010—2019年,中国新增石油探明地质储量主要分布在鄂尔多斯盆地、渤海湾盆地、准噶尔盆地等地区,以中浅层—中深层为主;新增天然气探明地质储量主要分布在鄂尔多斯盆地、四川盆地、塔里木盆地、东海陆架盆地等地区,以中深层—超深层为主。石油和天然气储量品质变差,丰度变低,埋深变大。中国新增油气探明储量的增长,主要集中在岩性地层油气藏、非常规油气藏、深层油气藏等领域。

In order to understand the growth trend of proven oil and natural gas geological reserves in China, this paper analyzes the distribution and change of the incremental proven oil and natural gas geological reserves discovered from 2010 to 2019 in China. The results show that the incremental proven oil reserves are mainly distributed in the areas such as Ordos basin, Bohai Bay basin, and Junggar basin,and accumulated in the middle-shallow to middle-deep formations in these basins;the incremental proven natural gas reserves are mainly distributed in the areas such as Ordos basin, Sichuan basin, Tarim basin, and East China Sea Shelf basin, and accumulated in middle-deep to ultra-deep formations;the quality of the incremental oil and gas reserves become worse, the abundance goes lower and the burial depth is deeper and deeper;and incremental proven oil and gas reserves are mainly preserved in lithologic oil and gas reservoirs, unconventional oil and gas reservoirs and deep oil and gas reservoirs.
