Temperature, thermal conductivity, and heat flow in a drilled hole near Oak Ridge, Tennessee

摘要: Temperature and thermal conductivity measurements from a 880-meter drilled hole (35°54.66′N, 84° 18.94′W) at Oak Ridge National Laboratory, Ridge, Tennessee, give value of 0.73±0.04/μcal/cm2 sec for the flow heat earth's interior. A detailed study Chickamauga limestone in depth interval 415 to 880 meters shows that various types limestones calcareous shales composing group depends approximately on shale content rocks according empirical relation: K = 6.6 - 0.036R, where is meal/cm 0C R percentage by weight residue insoluble dilute HCl. Repeated temperatures (3, 6, 13 months after completion drilling) show are no more than one-tenth degree equilibrium convection not important 7.6-cm hole, as shown fact significant differences temperature were obtained open with 3.2-cm casing.
