研究天然气藏的特征,正确划分天然气藏的类型,指导天然气勘探开发工作。根据国内外相关文献综合分析,分析显示前人对天然气藏类型及特征的研究主要基于圈闭类型、储层岩性、流体特征三方面,并且集中于严格圈闭界限内的气藏;将气源岩、储层、盖层孤立看待。建议以砂、泥岩组合为基础对气藏特征进行研究;将源、储、盖看作一起,研究分布于大范围连片储集体内的气藏。
Research the characteristics of natural gas reservoirs, properly divide the types of natural gas reservoirs and guide the exploration and development of natural gas. According to the comprehensive analysis and literature analysis at home and abroad, the previous studies on the types and characteristics of natural gas reservoirs are mainly based on trap types, reservoir lithology and fluid characteristics, and are concentrated in gas reservoirs with strict confinement limits. Source rocks, reservoirs, cap layer isolated view. It is suggested that the characteristics of gas reservoirs should be studied on the basis of sand and mudstone assemblages, and the sources, reservoirs and covers should be considered together to study gas reservoirs distributed in a wide range of contiguous reservoirs.
