深盆气藏是致密储层中与源岩相连的有根状气水倒置关系的气藏 ,是一类在成藏机理和分布规律方面都比较特殊的油气藏类型 ,常发育在盆地的构造低部位 ,在碎屑岩沉积盆地中具有广阔的勘探和发现前景。目前对深盆气资源量—储量评价方法的系统研究基本上仍是一个空白。根据深盆气藏的基本特征 ,结合油气资源评价方法论中的基本原则 ,较为扼要系统地提出了 10种深盆气资源量—储量预测方法 :特尔菲估计法、相似盆地地质条件类比法、盆地剩余资源量分析法、天然气聚散平衡计算法、地层流体异常压力恢复法、深盆气成藏条件分析预测法、盆地数值模拟法、深盆气藏甜点规模序列法、有效储层体积 (容积 )统计法和生产开发过程中的动态分析法等
Deep basin gas reservoirs are gas reservoirs with inverted gas-water inversion relationship with source rocks in tight reservoirs. They are a type of reservoirs that are quite special in hydrocarbon accumulation mechanism and distribution and are commonly found in basins The lower part has broad prospects for exploration and discovery in clastic sedimentary basins. At present, the systematic study of deep basin gas resource-reserve evaluation method is still basically a blank. According to the basic features of deep basin gas reservoirs and the basic principles in methodology of oil and gas resource assessment, this paper systematically presents 10 kinds of deep basin gas resource - reserve prediction methods: the method of Delphi, the analogy of similar basin geological conditions, Basin residual resource analysis, gas accumulation and balance calculation method, formation fluid abnormal pressure recovery method, deep basin gas accumulation conditions analysis and prediction method, basin numerical simulation method, deep basin gas reservoir scale sequence method, effective reservoir volume ( Volume) statistics and dynamic analysis of production and development process
