Abstract

Every winter from November of the first year to March of the next year, gas consumption would roar. As a result, all gas fields will increase gas rate to meet the needs. Traditionally, peak rate and rational rate are usually determined by methods like pressure drop rate, rate transient analysis (RTA), and numerical simulation. These approaches have been verified in the production, but they show flaws like heavy workload and poor time effectiveness. Theoretical research indicates that a plot of the increment of gas rate and the pressure drop rate should be linear, when pseudo-steady state is reached. In consequence, based on numerical simulation, correlations of the increment of gas rate and pressure drop rate were developed respectively for a series of reservoir pressure and well types. Field applications show that this method can not only process a huge batch of data in one time, but quickly estimate the rational and peak gas rate in real time.
