本文论述了地温技术的基本原理。通过探井资料统计,发现松辽盆地北部油气藏及其附近地区与水区相比具有高地温异常的特征,这与地温技术的原理是一致的。据此,应用地温技术在海拉尔盆地乌尔逊、贝尔凹陷预测了四个高地温异常的有利含油气区。综合地震技术和地质条件进一步分析,认为Tol井可能位于油水过渡带。

In this paper, the fundamentals of geothermic technology are discussed. Statistics on well data showed that reservoirs in the north of Songliao Basin and their neighbouring zones have high geotherm features in comparison with water - bearing zones. This appears to be in agreement with the principles of geothermic technology. As an appplied example, four high geothermal anomalies were discovered in Wuerxun and Baier depressions in Hailaer Basin, which are inferred to be prospective oil/gas bearing zones. Integrated analysis on seismic data taking account of geologic setting shows that Well Tol should be located in the oil-water’s transitional zones.
