Shaanxi Northern Gas Field; Hydrate Blockage; Anti-freezing and Anti-blockage Measures.Abstract
In response to the hydrate blockage problems occurring during the production of the Shaanxi Northern Gas Field in the winter of 2023, this paper conducts an in-depth analysis of the main causes of freezing and blockage, including the persistent low-temperature environment in winter, the relatively high hydrogen sulfide content in natural gas, and the mismatch between the process design of the gathering and transportation system and the existing production conditions. Meanwhile, it summarizes the actual implementation effects of various comprehensive anti-freezing and anti-blockage measures, and further puts forward the improvement direction and specific implementation paths for subsequent winter freezing and blockage prevention measures.
