A New Thermal Fluid Coupling Temperature Inversion for the Formation Characteristics of High-Yield Wells

  • 摘要:

    高探1井试油时,井底流体温度随着产量增大而升高,而现有测试资料分析方法无法解释该现象。为此,根据质量和能量守恒方程,考虑高温流体在地层中的渗流规律和在井筒内的流动规律、渗流和流动时的传热,建立了储层和井筒的热流耦合模型,利用该模型分析了温度瞬态数据,反演了高产井地层温度。高探1井的生产压力和温度数据反演结果表明,反演得到的温度曲线与实测温度曲线吻合良好,可以解释井底流体温度随产量升高的现象。研究表明,高产井地层特征温度反演方法能够定量分析地层热力学和渗流参数、确定高产井流体的产出位置,为生产管柱安全评价、现场生产决策、油藏认识和储量计算提供了理论依据。
