摘　　要：针对大涝坝凝析气田气藏储层有效厚度不大、储层非均质性较强等特征,利用储层描述技术重点开展下第三系苏维依组地层沉积相、储层物性特征、隔夹层纵横向展布规律分析。综合钻井、录井、地震数据等多种资料,应用petrel软件的地质建模技术实现大涝坝凝析气藏相控三维地质建模,直观地反映沉积相与储层属性参数在三维空间的展布特征,精确描述整个下第三系气藏储层的非均质性以及储层的展布特征。Aiming at the features of less gas reservoir net thickness and greater reservoir aeolotropism in Dalaoba Condensate Gas Field, by reservoir description, Tertiary Suweiyi formation and sedimentary facies analysis, reser- voir physical property features analysis, barrier and inter beds vertical -horizontal distribution rules and etc. are studied. On the basis of reservoir description, integrated drilling, logging, seismic data and other information, uti- lizing Petrel geology modeling technology, scientific 3D geology model controlled by sedimentary facies is launched in Dalaoba Condensate Gas Field, which directly reflects the distribution features of sedimentary facies and reservoir property parameter in 3D space, and precisely describes the whole Lower- Tertiary gas reservoir aeolotropism and reservoir distribution features, providing a resistant geology base for adjusting this reservoir exploitation solution.
