Experiment Study on the Scaling of Gas Wells in Songnan Gas Field

Abstract:

Gas field scaling is an important factor affecting the normal production of the gas wells. Scaling problems have been come into being in many production wells of Songnan gas field. The paper carried on experimental study and reason analysis on the scaling problem of Songnan gas field. The result shows that the fouling is mainly composed of calcium carbonate. The mainly reasons for the scaling are the incompatibility between Cacl₂ killing fluid and formation water as well as the pressure reduction around the wells.
