摘要: 生成条件和保存条件是决定一个盆地或探区天然气富集程度的主控因素.利用目前对我国重点含气盆地气源条件和保存条件的研究成果,定义并计算了基于其气源条件(生气量、生气强度和生气期)和保存条件(盖层质量、构造活动性)的各盆地的“含气远景得分”.在此基础上,对我国主要含气盆地天然气的勘探前景进行了对比和评价.我国各含气盆地中,含气远景得分在400分以上的盆地有四川盆地、莺琼盆地、塔里木盆地和鄂尔多斯盆地,表明这些盆地应该是我国天然气勘探潜力最大、勘探前景最好的地区.

Abstract: The degree of natural gas enrichment depends mainly upon the conditions of gas generation and preservation in a basin or an exploration region.By the use of the present research achievements about gas generation and preservation in the main gas-bearing basins,a concept of"score of gas potential"was defined.The score is related to the conditions of gas generation including the amount,intensity and period of gas generation,as well as to the preservation conditions including quality of caprock and structure activity.The scores of the important basins were calculated.The exploration prospect of natural gas for these basins was evaluated and compared on the basis of calculation.The results indicate that the Sichuan Basin,Yinggehai-qiongdongnan Basin,Tarim Basin and Ordos Basin are of the most favorable and greatest potential for gas exploration.

Key words: gas-bearing basin, natural gas enrichment, controlling factors, gas potential evaluation, exploration prospect
