摘要
伊朗Y油田储层埋藏深、油藏压力和温度高,产出地层流体中的沥青和蜡含量较高。油井在生产过程中,沥青和蜡会因温度、压力沿着井筒的降低而析出,导致生产管柱堵塞。为防止沥青和蜡的析出,保证长时间生产,压力、温度控制就变得尤为重要。为此,Y油田引进和应用了永置井下压力温度监测系统,对井底压力和温度进行实时监测,为生产管理和产能优化提供了依据。介绍了永置井下压力温度监测系统的组成及功能,分析了Y油田应用永置井下压力温度监测系统的必要性、温度压力对沥青和蜡析出的影响,对永置井下压力温度系统在Y油田的应用及其所起的作用进行了介绍。
The formation fluid produced from Iranian Y Oilfield contains high asphalt and high wax content due to deep reservoir depth and high pressure and high temperature.Because of the temperature and pressure drop along the wellbore,the precipitation of asphalt and wax plug the production string.In order to prevent the precipitation of asphalt and wax to ensure long production,pressure and temperature control becomes particularly important.Therefore,the permanent downhole pressure and temperature monitoring system was used for downhole real-time pressure and temperature monitoring for the purpose of production management and providing production optimization.The composition and function of various components of this system was introduced.The necessity of using this system in Iranian Y Oilfield,the impact of temperature and pressure on the asphalt and wax precipitation,the application and the role played by this system were analyzed.
