The Forecast and Analysis of Pressure of Gas Well of Western Sichuan Gasfield
摘要
Abstract
In western Sichuan gas field, measured pressure data in inclined gas well shows typical characteristics of two-stage. This paper analyzes the pressure gradient, and conclusion that it is influenced by gas-liquid slippage loss and inclined section. So we divided into vertical section and inclined section, and then statistically evaluate the common gas-liquid two phase pipe flow model. The conclusion is that the vertical gas production is less than 1 ~ 10~m3/d using no-slip model, otherwise we use Hagedorn and Brown model, and the DPI model is used in inclined section. Finally, forming a new model applies to inclined gas wells. Measured pressure data in Daniudi gasfield shows that the new model errors are less than 5%, and it is better than conventional model of pressure drop. Research results in deviated reservoir and condensate gas reservoir development have important application value and practical significance.关键词
