摘要
河东地区位于鄂尔多斯盆地东部,面积1.6×104km2,煤层气资源量4.5×1012m3,占全国煤层气总资源量的12.8%。该区是今后5~10年我国煤层气勘探开发的重点地区之一。从该区的煤层气资源背景、构造背景出发,认为河东中部地区是煤层气勘探开发最有利的目标区。理由是:①有利的构造部位可能具有良好的煤层气可采性;②多期生气提供了丰富的煤层气资源;③柳林试验区的勘探实践证明了中部地区具有煤层气勘探开发潜力。作为目前经济不发达的地区,建立河东煤层气主输气管线,是大规模开发煤层气的先决条件。另外,该区还是浅层天然气勘探的有利区,应采取浅层气、煤层气勘探并重,共同发展的策略。
The Hedong region is located in the east of Eerduosi Basin,being of an area of 1 6×10 4km 2.The coalbed gas resource extent in the region is 4 5×10 12 m 3,accounting for 12 8% that in the whole country.This region is one of the key regions of exploring and developing coalbed gas in the coming 5~10 years in China.In accordance with the coalbed gas resource extent and tectonic setting, it is considered that the middle part of Hedong region is the most beneficial target area for exploring and developing coalbed gas.The reasons are:①the beneficial tectonic portion may be of a good recoverability of coalbed gas;②the multistage gas generation provided abundant coalbed gas resources;③through the exploration practice at Liulin experiment area,it is proved that the middle part area is of the potential of exploring and developing coalbed gas.As an economy undeveloped area at present,it is the precondition for massively developing coalbed gas to set up the main gas pipline in Hedong region.In addition,this region is also the beneficial area for exploring shallow gas,therefore the policy of cooperatively exploring and developing the shallow gas and coalbed gas should be adopted.
