研究了北纬52°至58°间北海英国海区167口井的井底温度和岩性资料,并对全部主要地层单元的许多样品进行了热导率测量。虽然这些温度资料可能有很大误差,但足以肯定北海西部很多地方的热流是随深度变化的。在中央地堑和美德盆地内,上部1至2公里的热流约自50毫瓦/米~2,向下增加到约100毫瓦/米~2。而更西面的北海中部高地和东米德兰陆架则相反,浅部热流约80毫瓦/米~2,深处降至约50毫瓦/米~2。这些变化无论用热流折射或构造活动均不易解释,而很可能是深部水持续循环的产物。这种水循环很可能规模极大,且受主要断层控制。
Bottomhole temperature and lithology data for 167 wells in the North Sea from 52 ° to 58 ° North Latitude were studied and thermal conductivity was measured for many samples from all major stratigraphic units. Although these temperature data may be very large errors, it is enough to confirm that the heat flux in many parts of the western North China Sea varies with depth. In the Central Rift and the virtues basin, the upper 1 to 2 km of heat flow approximately increases from 50 mW / m ~ 2 to about 100 mW / m ~ 2. On the west side of the North Sea Midlands and the East Midlands shelf, on the contrary, the shallow heat flow is about 80 mW / m 2 and the depth drops to about 50 mW / m 2. These changes are difficult to interpret, either by heat flux refraction or tectonic activity, and are likely to be the product of sustained circulation of deep water. This water cycle is likely to be extremely large and controlled by major faults.
