摘　　要：为提高油藏注水开发效率,制定精细的分层配产配注制度,须针对水平井开展吸水及产液剖面的高效检测。对此,提出基于自适应矩估计优化算法(Adam算法)的水平井吸水及产液剖面测温反演方法。该方法首先利用储层与井筒内的温度分布模型构建反演目标函数,其次通过Adam优化算法,在最优化反演目标函数的过程中定量获取流动剖面。将该方法应用于阿曼Safah油田及新疆风城油田的两口水平井,采用生产测井工具测得各井段吸水量和井口测量的产液量对反演结果进行验证。结果表明:建立的反演方法不需要求解复杂的耦合模型,计算效率高,不仅可以定量监测流动剖面的动态变化、评价各层段的贡献率,还可半定量刻画水平井各层段相对渗透率的演化规律,指导现场制定更加精细化的配产、配注及增产方案。In order to improve the efficiency of water injection and design a finely stratified production and injection workflow,an efficient detection of the injection and production flow profile along a horizontal well is required.In this regard,a method based on the adaptive moment estimation optimization(Adam)algorithm was proposed to inverse the injection and production profile in a horizontal well using the temperature data.First,a temperature distribution model in both the reservoir and wellbore was applied to construct an inversion target function.Secondly,the Adam optimization algorithm was used to quantitatively obtain the fluid flow profile from solving the optimization target function.The method was used to analyze the flow profile of two horizontal wells in Safah Oilfield(Oman)and Fengcheng Oilfield(Xinjiang,China),respectively.The inversion results were verified against the sectional injectivity measured by production logging down hole and the total production measured on the surface.The results show that the inversion method has high computational efficiency without solving complex coupling models.It is not only capable of quantitatively monitoring the dynamic evolution of the flow profile and evaluating the contribution rate of each layer section,but also provides a semi-quantitative portrayal of the evolution law for the relative permeability in each section of horizontal wells,guiding the field engineers to design a more finely production and injection workflow,and stimulation schemes.
