| 摘 要： | 四川盆地西部是我国重要的天然气基地，属致密砂岩非常规天然气藏，具有独特的天然气地质学特征。依据钻达上三叠统的４０余口钻井资料，通过对油气显示、产层特征及测试等综合分析，总结和揭示了川西上三叠统的储、产层特征及其与天然气产出的关系，为老井挖潜和进一步勘探部署提供了参考意见。

| Abstract: | There is an important natural gas province Western Sichuan basin in China,where gas is produced from nonconventional gas pools of tight sandstones with some special characteristics of natural gas geology. Based on the information from more than 40 wells which down to Upper Trassic and synthesizing analyses through gas shows,producing features and well tests.It is summarized the reservoir and producing characteristics of Upper Trassic formation,the relationship between them and gas production in this paper which providing some reference suggestions for new exploration plan and old well re evaluation. |
