摘要/Abstract

摘要： 大牛地气田不断开发导致首站集中增压已不能满足气田开发的需要，同时在一期首站集中增压的基础上已经有约40%的气井压力接近管网压力，因此急需采取二次增压集输工艺。通过对气井油压的变化规律分析，确定二次增压的增压时机，并针对气田特点提出4种二次增压集输模式：（1）单井增压方案；（2）集气站分散增压方案；（3）区域集中增压方案；（4）区域集中增压+集气站分散增压方案。并从技术经济角度对4种模式进行对比优选，最终结果表明，区域增压+集气站分散增压方案既能满足管网外输的要求，又能保证经济效益，是二次增压方案中最合理的一种模式。

Abstract: The process of primary centralized supercharging is unable to fulfill the requirements of the Daniudi gas field due to its continuous development. In addition, the gas well pressure attains only approximately 40% of the pipe network pressure after the first centralized supercharging. Therefore, it is vital to perform a secondary supercharging process. Following the analysis of the changing pattern of oil pressure in gas wells, this study has determined the timing for the secondary supercharging and proposed the following four secondary supercharging modes according to the characteristics of the gas field:(1) single-well supercharging plan; (2) decentralized supercharging plan in gas gathering stations; (3) regional centralized supercharging plan; and (4) regional concentrated supercharging and single gas gathering station supercharging plan. Furthermore, this study has compared the four plans from the technological and economic point of view. The results show that the regional concentrated supercharging together with the single gas gathering station supercharging mode appears to be the most sensible strategy to fulfill the requirements of the external transmission of pipe network and achieve the economic benefits as well.

Key words: Daniudi Gas Field, exhausted gas pressure, upercharging timing, pipeline network simulation, supercharging plan
