为做好白庙气田储层条件及含气性分析，搞清其沉积特征与储层变化情况，认清气水分布规律，通过岩性分析、岩心观察和油气显示资料分析等，对白庙气田目的层储层的沉积特征进行了综合评价，详细阐述了储层的岩性、沉积相类型、砂体展布特征、储层物性以及非均质性，并对储层特征做了分类评价。研究认为：白庙构造西翼气源条件好，构造位置有利，砂岩储层发育，是近期现实的有利滚动目标区；同时，构造南部白5块也具有较好的成藏条件，也是滚动的有利区块。

In order to analyze the reservoir condition and hydrocarbon-bearing features,research the depositional characteristics and the reservoir change,and recognize the oil-water distribution of the main layer in Baimiao Gas Field,this paper evaluates the depositional characteristics of reservoirs and elaborates the lithological properties of reservoir,sedimentary facies types,sandstone body distribution,reservoir physical properties and heterogeneity based on the petrological analysis,core observation and oil and gas showings analysis. The results show the gas resource condition is good,the structure position is favorable and the sand layers
are well developed in the west limb of Baimiao Structure,which is the most favorable target area of progressive exploration in recent period. Block Bai 5 in the south of structure has a favorable reservoir-forming condition and is also a favorable target area of
progressive exploration.
