大庆长垣西部地区地热资源潜力分布

Potential Distribution of Geothermal Resource in Western Region of Daqing Placanticline

地热资源是一种清洁的、可再生的新能源。大庆长垣西部地区地处松辽盆地地温梯度的高值构造带,属于典型的沉积盆地型中低温地热资源。该区地温场受到莫霍面埋深浅、深大断裂发育等因素的影响,中部含油气组合等热储层温度较高,通过对各个热储的物性特征以及地温特征进行综合评价,将研究区划分为了三类热储,并估算了控制资源量,有效地指导地热资源的合理开发利用,取得了明显的经济效益和社会效益。

Geothermal resource is a clean and renewable new energy.The western region of Daqing Placanticline is located the high geothermal gradient region in Songliao Basin,and belong typical medium-low temperature geothermal resource of sedimentary basin.As affected with shallow depth of Moho surface and developmental deep fault rupture in this region,the temperature of middle oil and gas-bearing reservoirs is great higher.By composite evaluation of each reservoir petrophysical and geotemperature field properties,three types geothermal reservoirs are divided and their control reserves are estimated,which guides reasonable exploitation and utilization of geothermal resource effectively,and then acquires obvious economic and social benefits.
