【摘要】 沉积岩原地热导率是盆地热结构和热演化研究的重要参数，在不同物性的岩石中，热导率是控制油气盆地地温和热流的重要因素。本文介绍了利用平均密度、补偿中子、声波时差、自然伽马、自然电位、深探测电阻率、中子寿命等地球物理测井资料计算油气盆地中沉积岩岩性组成的方法，并在东营盆地Y101和B18钻井中，具有较全的地球物理测井资料的部分井段上，计算了各深度处沉积岩岩性的组成及其原地热导率值。更多还原

【Abstract】 The geothermal conductivity of sedimentary rock is an important parameter for geophysicists to analyse geothermal distribution and geothermal evolution in a sedimentary basin, and it is an essential factor which controls geotherm and geothermal flux in hydrocarbon basin. Some methods are recommended which detect lithologies of sedimentary rocks in hydrocarbon basin by using different data of average density, compensated neutron, acoustic wave, natural gamma ray, natural potential,deep resistivity and neutron lifetime logs. Geophysicists estimated the lithologies and geothermal conductivities at different depths of the borehole sections, where various geophysical log data have been collected, in Y101 and B18 boreholes in the Dongying basin.更多还原
