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.

Key words: tight sandstone, gas reservoir recognition, well log, method
