H127块SAGD试验区储层及隔夹层特征研究

Characteristics of Reservoir and Interlayer in SAGD Test Area of Bblock H127

利用研究区岩心化验和测井等资料分析SAGD试验区内储层及隔夹层特征。研究表明:H127块SAGD试验区内储层属于扇三角洲前缘亚相沉积,储层类型属于高孔高渗储层。储层砂体发育以兴Ⅱ2为主,平面上砂体总体沿北西-南东向展布,向北东、南西变薄。

The characteristics of reservoir and interlayer in sagd test area are analyzed by using core testing and logging data.The study shows that the reservoir in SAGD test area of block H127belongs to the subfacies deposition of fan delta front,and the reservoir type belongs to high porosity and high permeability reservoir.The development of reservoir sand body is mainly xingⅡ2,and the sand body on the plane is generally distributed along the northwest-southeast direction,thinning to the northeast and southwest.
