Prediction Method of Production Performance of Gas Well

Abstract:

Production performance prediction is the foundations for technical and economic evaluation of production system of gas well. Based on Material Balance Equation and Back Pressure Equation, it provides two prediction models of gas well performance, for two production modes (constant production mode and constant pressure mode) separately. These models can exhibit the change of some important production performance factors with time, such as Production, Recovery Efficiency, Wellhead Pressure, Bottom Hole Pressure, Formation Pressure, etc. By examples and discussion, it can be seen that, this method for predicting production performance is feasible and reasonable. Compared with other methods, the prediction model method expands the prediction range. It can predict the whole production periods of gas well (Stable Period, Decline Period, and Pressure-increasing Period).
