依兰煤田煤层气勘探开发成果及前景展望

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 Coalfield Coalbed Methane Exploration Results and Development Prospects

Yilan mining area is located in Dalianhe town,Yilan County,Heilongjiang Province,east coast of Songhua River.Dalianhe open-pit of Yilan mining area is mining,with an annual production of 4 million tons.Yilan coalfield has 197 million tons of coal reserves,forecasted coal resource is 361 million tons.The coalbed methane resources is 5.273 billion m3,all buried in 1500 meters.Yilan mining area coalbed methane exploration and development,either from the geological structure,coal-bearing strata,thickness of coal seam,coalbed methane resources,reservoir characteristics,the single well productivity or other aspects to see all has very wide prospect.
