根据对渤海湾盆地沾化凹陷泥质岩、粉砂岩、砂岩和白云岩平行层面与垂直层面方向热导率差异及孔隙连通性差异特征的研究，探讨了沉积岩平行层面与垂直层面方向热导率与孔隙连通性之间的关系。热导率实验结果表明：沾化凹陷泥质岩、粉砂岩和砂岩的平行层面方向热导率大于垂直层面方向热导率；白云岩的平行层面方向热导率小于垂直层面方向热导率。沉积岩平行层面与垂直层面方向热导率差异和孔隙连通性差异之间具有正相关性。孔隙特征分析结果表明：孔隙连通性较好方向，热导率也较高；孔隙连通性较差的的方向，热导率也较低。

Based on the thermal conductivity and pore connectivity differences between parallel and perpendicular to the bedding plane of argillaceous rock,siltstone,sandstone and dolostone of Zhanhua depression in Bohai Bay basin,we delineated the relationship between the thermal conductivity and the pore connectivity differences.According to the experimental results,the thermal conductivity parallel to the bedding plane of argillaceous rock,siltstone and sandstone are higher than that perpendicular to the bedding plane.And the thermal conductivity parallel to the bedding plane of dolostone is lower than that perpendicular to the bedding plane. Between parallel and perpendicular to the bedding planes of sedimentary rocks,it is positive correlation between thermal conductivity difference and the pore connectivity difference.The thermal conductivity is higher in the direction that pore connectivity is better.And the thermal conductivity is lower in the direction that pore connectivity is poor.
