摘　　要：海拉尔盆地为中–新生代的断陷–坳陷型盆地,沉积厚度约6000 m,可划分为五个一级构造单元,细分为16个凹陷,含有丰富的石油与天然气储量。本文对海拉尔盆地的陈旗凹陷和呼伦湖凹陷的煤岩储层样品进行了气测渗透率、气测孔隙度试验,并结合实验结果分析了两大凹陷煤岩储层的渗透性及孔隙特征,在此基础上分析了海拉尔本地煤岩储层的孔渗基础物性。Hailaer basin is a fault depression-depression basin of the Meso-Cenozoic, with a sedimentary thickness of about 6000 m. It can be divided into five first-order structural units, subdivided into 16 depressions, and is rich in oil and natural gas reserves. In this paper, gas permeability and gas porosity of coal and rock reservoir samples in Chenqi sag and Hulun Lake sag of Hailaer basin were tested, and the permeability and porosity characteristics of coal and rock reservoirs in the two sag were analyzed based on the experimental results.
