After nearly a decade of exploration and development, Yan'an gas field has entered the stage of rapid production.Gathering and transportation technology has evolved from the high-pressure to the “most are medium-pressure, other are low-pressure or skid-mounted LNG”.However, a number of problems were also exposed during the on-site production process.Firstly, dynamic analysis and management of gas well production cannot be satisfied by single wells wet metering.Secondly, the amount of methanol injection is large and the distribution of injection is unreasonable.Thirdly, severe fluid accumulation often occurs in pipelines.Fourthly, foam drainage process affects the normal production of downstream equipment.Fifthly, the degree of wellhead informatization, station standardization and digitization of production is low. A series of technical innovations and researches has been carried out on site.The construction of standardization, modularization, informatization, safety and environmental protection has been promoted by means of transforming pipelines, adding equipment, formulating regulations, applying new technologies and introducing new achievements.
