For bottom water reservoir, it is regularly to avoid shooting the water layer so as to prevent the bottom water intrusion, but now there has been a“shooting gas and water layers, both gas and water producing”pattern to produce gas, and may also prevent the water intrusion. The Moxi gas field is a typical water bearing gas field in Sichuan. To further understand the relations between the dynamic production characteristics and reservoir features, five types of water-gas ratio curves are summarized after comparison between avoiding shoot water layer and water-gas commingle production, that is, the plateau, a slow ascent, rapid ascent, down segment and hops. We analyze each curve type and its reservoir characteristics, and then draw the water/gas ratio plate. In the study area, we identify the range of slopes of water/gas ratio curve. The field application has proved that the dynamic characteristics of recovery of both gas and water are overall accordant to the reservoir characteristics, indicating that the plate is practically helpful to correctly understand the water flooding patterns of gas reservoirs with bottom water. And, the internal reservoir gas and water two-phase flow changes should be further studied.
