摘要:

地热能的开发利用正成为中国新能源领域发展的重点。国家"十三五"(2016—2020年)地热能发展规划和一系列保障措施的出台将加快推动地热产业的发展。拥有丰富水热型地热资源的油田企业可将油田地热能用于原油集输、建筑物采暖、热洗油管等,替代燃油、燃气和燃煤。根据油田地热地质的特点,地热资源的评价可基于随机模拟法、单元容积法和类比法。通过随机模拟法和单元容积法对中国11个盆地或区块中埋深浅于4 km的水热型地热资源进行系统评价,地热资源量为31 784.45×1018J,地热水资源量为375 085.18×108m3,可采地热资源量为47.68×1018J/a。中国东部地区含油气盆地的地热资源普遍具有温度高、埋深浅、开发利用经济效益好的特点。地热资源的分级评价可为有序、规模化开发利用油田地热能奠定基础。

Abstract:

The exploitation and utilization of geothermal energy is becoming the focus of new energy development in China. The national 13th Five-year Plan(2016-2020) for geothermal energy development and a series of safeguard measures will accelerate the development of geothermal industry. Oilfield enterprises with rich hydrothermal geothermal resources can use geothermal energy for crude oil gathering and transportation, space heating, oil tube washing, etc., replacing fuel oil, fuel gas and fuel coal. Based on the geological characteristics of geothermal energy in oilfields, the evaluation of geothermal resources can depend on the stochastic simulation, volumetric evaluation and analog method. According to the systematic evaluation of hydrothermal geothermal resources buried less than 4 km in 11 basins or blocks by the stochastic simulation and volumetric evaluation, the geothermal resources amount is 31 784.45×1018J in China. Moreover, the geothermal water resources amount is 375 085.18×108m3, and the recoverable geothermal resources amount is 47.68×1018J/a. The characteristics of the geothermal resources of petroliferous basins in eastern China show high temperature, shallow burial depth, and low-cost development and utilization. Grading evaluation of geothermal resources can lay the foundation for the ordered and large-scale development and utilization of geothermal energy in oilfields.

Key words: development potential of geothermal resources, grading evaluation of resources, evaluation methods of geothermal resources, geothermal resources in oilfields, petroliferous basin
