作为中国石油工业老字号,延长石油的资源区块主要是鄂尔多斯特低渗透油藏,其开采难度被业界形容为“磨刀石上挤石油”。因此,创新寻求后备资源、接续能源便成为延长石油亟待突破的当务之急。通过相关研发攻关,延长石油发现鄂尔多斯盆地中生界陆相沉积地层具备较好的页岩气成藏条件并具有相当规模的页岩气资源量,2011年4月,延长石油在延安下寺湾地区压裂柳评177井并成功点火,成为中国第一口陆相页岩气出
As China’s oil industry is the old name, extending the oil resource block is mainly Ordos low permeability reservoir, the difficulty of mining industry described as “grindstone squeeze oil ”. Therefore, looking for an innovative backup resources, connecting energy has become the urgent need to extend the urgent task of oil. Through related research and development, Yanchang Petroleum discovered that the Mesozoic continental sedimentary formations in the Ordos Basin have good shale gas accumulation conditions and a considerable amount of shale gas resources. In April 2011, Yanchang Petroleum was found in the Lower Temple of Yan’an The area fractured Liuzai 177 well and successfully ignited it and became the first continental continental shale gas outlet
