依兰矿区位于黑龙江省依兰县达连河镇境内,松花江东岸。依兰矿区达连河露天矿正在开采,年产量可达400万t。依兰煤田煤炭保有储量1.97亿t,预测煤炭资源量3.61亿t。煤层气资源量为52.73亿m3,均埋藏于1 500 m。依兰矿区煤层气勘查开发,无论从地质构造、含煤地层、煤层厚度、煤层气资源量、储层特征、单井产能等多方面看,依兰煤田煤层气勘探开发的前景非常广阔。
Yilan mine is located in Dalianhe, Yilan County, Heilongjiang Province, east of the Songhua River. Yalian mine Dalinhe surface mine is mining, the annual output of up to 4 million t. Yilan coal reserves of 197 million tons of coal reserves, forecasting 361 million tons of coal resources. The amount of CBM resources is 5.273 billion m3, both buried at 1 500 m. In terms of geological structure, coal-bearing strata, thickness of coal seam, amount of CBM resources, reservoir characteristics and single-well productivity, the prospect of CBM exploration and development in Yilan Coalfield is very promising.
