摘要
为解决热采水平井射孔段均匀注汽这一难题,在建立水平注汽管柱内汽、液2相流热动力学模型及配注器节流模型的基础上,根据沿管柱长度方向流量分配均衡原则,将注汽段流量均匀分布作为目标函数,应用数值仿真技术对配注器+油管组合型注汽管柱的配注器数量、泄流孔个数及布置形式等进行了优化。依据仿真结果开发了水平井注汽参数优化设计软件,该软件在胜利油田滨南采油厂进行了初步应用,达到了预期效果。
To solve the problem of uniform steam injection along the perforation interval of horizontal well, based on the thermodynamic model of steam in the steam injection string and throttling model of flow regulator, the structure parameter of steam injection string was optimized according to the uniform flow principle with numerical simulation method. Based on the simulation results, optimized steam injection parameter software for horizontal well was developed. This software was applied in Shengli oilfield, with expected achievement.
