Gas production

Could some expert analyze the relationship between oil pressure and casing pressure, as well as discuss the causes of freezing, blockages, and fluid accumulation in gas gathering pipelines in winter and the solutions to these problems?
The question is too general; it would be better to refine it further. For example, the previous small process. \"Gauge pressure\" is probably a term specific to your equipment; if this issue occurs in the relevant section, it might be easier to understand.
In a perfect gas well, the inlet pressure is slightly lower than the oil pressure and also slightly lower than the casing pressure; issues can be identified by observing the changes in these inlet pressures as well as in the amount of oil and gas produced. Freezing and blockage-related fluid accumulation can occur at the bottom of the well, in the pipelines on the surface, and within the station; for the first two locations, measures such as allowing fluid to flow into the station and increasing the amount of alcohol injected can be taken, while within the station, hot water is generally used to deal with this issue
