摘　　要：非常规天然气是油气田重要的资源接替领域之一,研究和探索大庆油田及其外围盆地非常规天然气资源勘探潜力对该油田实现可持续发展具有重要意义。大庆油田及其外围盆地包括松辽盆地北部、海拉尔、大杨树、鹤岗等10多个中新生代陆相沉积盆地。通过分析该区油气钻井、煤田钻孔和野外剖面实测资料,结论认为:该区有着较丰富的非常规天然气资源,主要为致密砂岩气和煤层气,前者在松辽盆地北部和各个外围盆地广泛存在,估算天然气资源量达1.2×1012m3;后者分布在海拉尔、鹤岗、鸡西等外围盆地,预测资源量达2.1×1012m3。该区非常规天然气资源勘探程度很低,大部分地区尚未开展有针对性的勘探工作。建议加强前期研究和勘探选区评价,进行开发先导性试验并开展国内外合作,增强技术储备,探索出有效的勘探开发方式。近期可以选择松辽盆地北部深层致密砂岩气、海拉尔盆地和鹤岗盆地的煤层气作为该区勘探开发非常规天然气资源的突破重点。Unconventional natural gas is the key to the resource replacement of hydrocarbon fields.Prospecting the unconventional gas potentials of the Daqing Oil Field and its peripheral basins is of great significance to the sustainable development of PetroChina Daqing Oilfield Company.In view of this,the study area includes the Daqing Oil Field and over 10 Meso-Cenozoic sedimentary basins including the northern Songliao Basin,Hailaer,Dayangshu,Hegang,Jixi,etc..An analysis of the oil/gas well data,borehole data of coalfield and outcrop data reveals that the unconventional gas resources in the study area is abundant and is dominated by tight gas and coalbed methane gas.The tight gas mainly occur in the northern Songliao Basin and several other peripheral basins with the estimated gas resources of 1.2 tcm,while the coalbed methane gas is mainly distributed in the peripheral basins such as Hailaer,Hegang and Jixi with the estimated gas resources of 2.1 tcm.However,the exploration of unconventional gases in the study area is still in its initial stage.It is proposed to strengthen geologic study and recognition and evaluation of plays,carry out pilot development,and seek for effective exploration and development schemes through cooperation with domestic and overseas research institutes.In the near future,exploration and development of unconventional gases will focus on the tight gas in the northern Songliao Basin and on the coalbed methane gas in the Hailaer and Hegang basins.
