| 英文摘要 | A total of 65 new heat flow values were calculated in terms of newly determined thermal conductivity and collected temperature logging data. Using these data coupled with those from previous studies, we have constructed a geothermal gradient map as well as a heat flow map for the northern marginal basins of the South China Sea. Furthermore, geothermal characteristics of these basins and their relationship with oil and gas field distribution were analyzed. The results show that the four sub-basins located in the northern South China Sea, namely Pearl River Mouth Basin, Qiongdongnan Basin, Beibuwan Basin and Yinggehai Basin, are typical "hot basins" with average heat flow values 68. 7 +/- 11 mW/m(2), 71. 1 +/- 13 mW/m(2), 65. 7 +/- 8. 9 mW/m(2), 74. 7 +/- 10 mW/m(2), respectively. The overall heat flow distribution pattern in the study area, which gradually increases from the shelf to the slope consistent with crust thinning trend, are generally controlled by regional tectonic setting, meanwhile some high local heat flow anomalies are likely to be attributed to faults and magmatic activity. The geothermal field may control and restrict oil and gas accumulation in the study area. Inlight of exploration results from these basins, we find that the gas fields are mostly located in the high heat flow basins (depressions) while the oil fields are more likely to be present in basins with relatively lower heat flow values (depressions). |
