摘　　要：花沟气田是胜利探区惟一的纯气田 ,天然气资源丰富 ,其分布复杂而又独具特点。与其他油气田相比 ,该气田存在多种成因类型的天然气藏 ,如甲烷气藏、二氧化碳气藏 ,以及甲烷、二氧化碳和氮的混源气藏。花 5 0 1井氮气含量中混有高含量的氦气 ,其含量达到 3.0 8% ,国内少见 ,花 4井还钻遇凝析气。文章结合近几年的研究成果 ,从气源、气藏类型、储集层特征等方面分析了多种类型气藏的成藏规律 ,有利于指导该区天然气勘探。Huagou gas field is the only net one in Shengli exploration area, which has rich natural gas resource with complex distribution and unique features. Many origin types of natural gas reservoirs exist in the field compared with other oil-gas fields, such as CH_4, CO_2 and combined source gas reservoirs of CH_4, CO_2 and N_2. The nitrogen content in well Hua 501 mixed with high content of He (up to 3.08%) rarely seen in our country. Condensate gas has been drilled in well Hua 4. The reservoir-forming rules of many types of gas reservoirs are analyzed from the a s pects of gas source, gas reservoir type, reservoir characteristics combined with the research results in recent years, favorable for guiding the exploration of the natural gas in this area.
