Abstract

Abstract: Production allocation plays a very important role in gas well production. The existing production allocation are generally done based on 1/6~1/3 of the open flow rate. On the basis of studying the non-Darcy effect of gas in the formation, the concept of production loss rate was proposed. By quantifying the production loss caused by the non-Darcy effect, a chart of gas well production loss rate and dimensionless production was established. For each production allocation, the corresponding yield loss rate can be obtained. Therefore, reasonable production allocation can be carried out based on the yield loss rate. For certain high-pressure gas reservoirs, due to high formation pressure and high gas compression, the non-Darcy effect is not strong under formation conditions, and the rate of production loss is relatively low. This type of gas wells can increase production by a certain amount. This production allocation method can quantify the non-Darcy flow loss of reservoir gas and achieve reasonable production allocation of gas wells. This research achievement can further optimize the reasonable production allocation system of gas wells on the basis of conventional production allocation methods, better meet the long-term stable and efficient development needs of gas wells, and provide useful reference for gas reservoir development.

Key words: productivity equation, non-Darcy flow, yield loss rate, optimal production allocation, gas reservoirs
