中国陆上四大天然气产区
|
摘要
凡年产天然气在60×10~8m~3(相当年产油500×10~4t)以上盆地(地区)称为大产气区。中国陆上按年产量从大至小有鄂尔多斯盆地、四川盆地、塔里木盆地和柴达木盆地四个大产气区。鄂尔多斯盆地、塔里木盆地和柴达木盆地大产气区煤成气或煤型生物气的产量占86%以上,其气组分为烷烃气占95%以上的经济效益高的优质气;四川盆地大产气区以产含H~2S油型气为主,页岩气次之,煤成气最少。四大产气区2017年底共累计探明气层气地质储量100 450×10~8m~3,年产量为1 060. 5×10~8m~3,分别占全国气层气地质储量和年产量的82. 97%和85. 99%,因此,四大产气区气层气的储量和年产量是中国天然气工业发展的主要保证和基地。
Large gas province refers to the basin with annual gas production over 60 × 10~8 m~3( equivalent to annual oil production of 500×10~4 t). According to the annual gas production,there are four major gas provinces in China: Ordos Basin,Sichuan Basin,Tarim Basin and Qaidam Basin. In the Ordos,Tarim and Qaidam basins,the production of coal-derived gas or coal-derived biogas accounts for more than86 %,and its gas composition is composed of high-quality gas with high economic benefit,which accounts for more than 95 % of alkane gas. The gas province in the Sichuan Basin is dominated by H~2 S-bearing oil-derived gas,followed by shale gas,and then coal-derived gas. At the end of 2017,the total proven geological reserves of gas zone gas in the four major gas provinces were 100 450×10~8 m~3,with an annual production of 1 060. 5×10~8 m~3,accounting for 82. 97 % and 85. 99 % of the total geological reserves and annual production of gas zone gas in China,respectively. The reserves and annual production of gas in the four major gas provinces are the main guarantee and base for the development of natural gas industry in China.
