在全国煤层气资源评价中，将煤层气资源划分为探明储量、控制储量、预测储量和远景资源量。全国共获得可采煤层中风化带以下煤层甲烷含量大于或等于４ ｍ ３ ／ｔ 、埋深２ ０００ ｍ 以浅的煤层气资源量为１４ ．３３６ ９４４×１０１ ２ ｍ ３ ：其中预测储量９ ６７５ ．１０ ×１０８ ｍ ３ ， 远景资源量１３ ．３６９ ４３４ ×１０１ ２ ｍ ３ 。全国有３５ 个目标区的资源丰度大于１ ．５ ×１０８ ｍ ３／ｋ ｍ ２ ，有４９ 个目标区的资源丰度介于（０ ．５ ～１ ．５） ×１０８ ｍ ３ ／ｋｍ ２ 之间，有３１ 个目标区的资源丰度小于０ ．５ ×１０８ ｍ ３／ｋ ｍ ２ 。埋深小于１ ５００ ｍ 的煤层气资源量９ ．２５６ ０７８ ×１０８ ｍ ３ ，埋深１ ５００ ～２ ０００ ｍ 的煤层气资源量５ ．０８０ ８６６ ×１０８ ｍ ３ 。全国有煤层气资源量大于１ ０００ ×１０８ ｍ ３ 的大型目标区２８ 个，煤层气资源量介于（２００ ～１ ０００）×１０８ ｍ ３ 之间的中型目标区２８ 个，煤层气资源量小于２００ ×１０８ ｍ ３ 的小型目标区５９ 个。
In the national CBM resource evaluation, CBM resources are divided into proved reserves, controlled reserves, predicted reserves and long-term resources. The total coalbed methane content below 4 m 3 / t below the weathering zone in the coal seams that can be obtained in the country is 14 and the burial depth is 2 000 m. 336 944 × 101 2 m 3: of which 9 675 is forecasted. 10 × 108 m 3, long-term resources 13. 369 434 × 101 2 m 3. There are 35 target areas in the country with abundance greater than one. 5 × 108 m 3 / k m 2. The resource abundance of 49 target areas ranged from (0.5 ~ 1.5) × 108 m 3 / km 2, and the resource abundance of 31 target areas was less than 0. 5 × 108 m 3 / k m 2. CBM resources less than 1 500 m deep 9. 256 078 × 108 m 3, CBM resources of 1 500 ~ 2 000 m depth 5. 080 866 × 108 m 3. There are 28 large-scale target areas with CBM resources larger than 1 000 × 108 m 3 in the country. There are 28 medium-sized target areas with CBM resources ranging from (200 to 1 000) × 108 m 3. The CBM resources are less than There are 59 small target areas of 200 × 108 m 3.
