The change of oil-gas field production experiences the process of rise, stability, and decline. After a conventional gas well goes into production, production remains stable for a certain period of time then comes to a declining stage. Forecasting for this stage of production has an important sense for the adjusting of exploration and exploitation design, surface construction, economic evaluation of the gas well and increasing production measure decisions, and so on. Based on the research of oil-gas wells production decline in recent years, this paper studied about the relationship of the three Arps′s production decline curves, came to the conclusion of production decline following a hyperbolic decline, summed up the major factors impacting the production decline of gas wells, analyzed the effect on production decline performance by the change of these factors, and used the production decline curves to forecast the descending phase of gas well production.
Key words： Arps; Production decline; Curve; Decline performance.
