摘要
油田地热资源评价和开发利用一直是我国陆上沉积盆地内中-低温水热型地热资源研究的重点工作。本文介绍了油田地热资源评价的基本思路和评价方法,并以大庆油田、华北油田和辽河油田为例,通过地温场研究、热储特征分析、岩石热物性测试,按照新建立的油田地热资源评价分级体系,重新评价了油田区的地热资源量。3大油田区11个层系地质资源总量为10 934×10^(18)J,地热水资源量为86 607×10~8 m^3,其中,可采水资源量为19 322×10~8 m^3,可采地热能资源为425×10^(18)J。根据油田采出水和综合利用等5种开发利用方式,评估了油田地热能开发潜力,为我国地热资源评价和油田地热规模化开发奠定了基础。
Geothermal resources assessment and utilization in oilfield has always been an important work in low temperature hydrothermal sedimentary basins. The basic concept and evaluation method of oilfield geothermal resources evaluation has been discussed in this paper. Taking Daqing oilfield, Huabei oilfield and Liaohe oilfield as an example, the geothermal resources in these three oilfields have been reevaluated through geothermal field analysis, geothermal reservoir characteristics analysis, rock thermophysical properties test, and according to the new classification system of geothermal resources evaluation in oilfields. The geothermal geological resources in three oil fields of 11 layers amount to 10 934×10^18 J, geothermal water resources amount to 86 607× 10^8 m3. The recoverable water resources is 19 322× 10^8 m3, recoverable heat energy resources amount to 425× 10^18 J. According to 5 kinds of geothermal exploration and comprehensive utilization, the oilfield＇s geothermal energy development potential has been evaluated. This study will lay the foundation for the evaluation of geothermal resource in China and large-scale geothermal development and utilization in oilfields.
