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。
The geothermal conductivity of sedimentary rocks is an important parameter for the study of thermal structure and thermal evolution in the basin. Among the rocks with different physical properties, the thermal conductivity is an important factor for controlling the geothermal and heat flux in the oil and gas basin. This paper presents a method for calculating the lithologic composition of sedimentary rocks in oil and gas basins using geophysical log data such as mean density, compensated neutron, time lag, gamma ray, natural potential, deep probing resistivity and neutron lifetime. Y101 and B18 drilling, with more complete geophysical well logging data section of the well section, calculated at each depth of sedimentary rock lithology composition and in situ thermal conductivity values.
