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
