摘　　要：中国重庆川东地区是四川盆地天然气的主要储产地区 ,对川气东输工程具有举足轻重的影响。但由于勘探难度增大 ,使储量增长速度明显放慢 ,储采比快速下降 ,若无新的发现 ,将无法保证长期高产稳产。文章针对该地区天然气储量资源的结构及现状 ,分析了二叠系、三叠系滚动勘探开发的潜力 ,认为在该区实施二叠系、三叠系滚动勘探开发是一项投资省、见效快的工作 ,指出重庆气矿近期的发展方向应针对二叠系、三叠系实施滚动勘探开发。文章还提出了相应的技术保障措施和近期工作的初步设想 。Chongqing-East Sichuan region is the principal reserve production area of natural gas in Sichuan Basin.Which has a decisive influence on Sichuan-to-east natural gas transmission project. Because the exploration difficulty increased , the reserve accreting velocity was obviously slowed down and there was a rapid drop in the reserve-production ratio. If there is no new discovery, a long-term high-stable production can't be maintained. In consideration of the structure and present situation of the gas reserves and resources in this region, through analyzing the potential of the rolling exploration and development carried out for Permian and Triassic, it is pointed out in ths paper that such a rolling exploration and development is a job of small investments and quick returns, which should be the trend of the chongqing Gas Field in the near future. Finally, relevant technical measures and a tentative idea of short-term work are put forward and the short-term work targets are optimized in the paper also.
