| 英文摘要 | The characteristics of present-day heat flow and lithospheric thermal structure, which are the comprehensive reflections of lithospheric tectono-thermal evolution and constraints of thermal history reconstruction, are very important for basin dynamics research and hydrocarbon resource assessment in sedimentary basins. We report 11 newly measured high-quality terrestrial heat flow data based on systematical well-logging temperature data in 102 new boreholes, oil-testing temperature data in over 400 new boreholes and detailed thermal conductivity testing using optical scanning method of 187 representative samples in 15 wells. The results show that the present-day geothermal gradient varies from 11. 6 to 27. 6 degrees C/km with a mean of 21. 3 +/- 13. 7 degrees C/km, while the heat flow ranges from 23. 4 to 56. 1 mW/m(2) with an average of 42. 5 +/- 7. 4 mW/m(2). The Junggar basin appears to be a cool basin in terms of its thermal regime. As the same as geothermal gradient, the distribution pattern of heat flow is controlled by basement structure and shows the following characteristics. (1) Relatively high heat flow values over 45 mW/m(2) are confined to the Eastern Uplift and the Luliang Uplift. (2) The Wulungu Depression, Central Depression and Western Uplift are characterized by low heat flow values about 40 similar to 43 mW/m(2). (3) The lowest heat flow (33. 9 mW/m(2)) occurs in the Southern Depression. The terrestrial heat flow consists of crust heat flow varying from 18. 8 to 26. 0 mW/m(2) and mantle heat flow varying from 16. 5 to 23. 7 mW/m(2). The Junggar basin is typical of 'cold crust and cold mantle' thermal structure, with the ratio of crust heat flow and mantle heat flow ranging from 0. 79 to 1. 58. The mantle heat flow values are consistent with the fluctuation of Moho surface, that is, uplift zone has higher mantle heat flow than the sag zone. |
