摘要
本文系统阐述了松辽盆地地热场特征,给出了松辽盆地大庆长垣及周围地区热力学模式和热应力计算方法,分析了盆地中央坳陷热应力场性质及分布特征,探讨了盆地地热和热应力在油气运移中的作用。
The thesis expounds the features of geothermal field in Songliao Basin, proposes thermodynamic pattern and calculation method of thermal stress of Daqing placanticline and adjacent areas in Songliao Basin, and analyses character and distribution feature of thermal stress field of central depression in Songliao Basin. On the basis of the above-studied results, the role of geothermal and thermal stress of Songliao basin on migration of oil and gas is discussed.
