| 摘 要： | 致密砂岩气层识别较常规砂岩气层要困难得多。因为致密砂储层的孔、渗性能非常差,从而使许多方法的识别效果都不理想,利用川西某气田实际测井资料,仔细研究了几种常用气层识别方法对该类气层的识别效果,分析了各种方法的影响因素,并提出了几种比较合理的建议,以使其他同行们能起到借鉴作用。 |

| Abstract: | It is more difficult to recognize a tight sandstone gas layer than a regular sandstone gas layer. The extremely poor porosity and permeability of the tight sandstone makes many traditional recognition methods less satisfying. Based on the well log materials from a gas field in northwestern Sichuan, This paper makes a detailed analysis of the recognition effects of several common methods as well as the factors affecting the results. Some relatively reasonable proposals are presented for the reference of the trade. |
| Keywords: | tight sandstone gas reservoir recognition well log method |
