Abstract: Well logging curves are carried out normalization correction, the conventional logging data could identify the oil and water beds, but also the oil reservoir with obvious variation and great burial depth. While the shallow buried gases reservoir, the normal interpretation ways aren’t enough to meet the production. After analyzed the characteristics of gas reservoir indication curves such as neutron, density and acoustic logging, the log interpretation methods which base on 3 porosity log curves is proposed. According to the actual well testing, these methods used to identify the shallow-buried natural gas reservoir are economically feasible.
