摘要:
 含水率高是油井低效生产的关键，也是制约油藏高效开发的最主要问题，其中产液剖面及控水效果的分析与计算一直困扰着现场生产。根据单井的分层合采数据及控水需求，采用小层厚度、渗透率加权的方法，确定小层配液系数；再与小层含水饱和度加权确定小层配水系数，引入小层配水修正系数，通过拟合得到与实际油井一致的含水率，实现产液剖面的预测；根据产液剖面预测结果，设计了控水增油和提液增油的分层控水效果量化方法。实例应用表明，产液剖面预测方法可保证各层产液误差、产水误差均在5%以内，合采误差均小于1%；在高产水层控液量较低的情况下，随控液量增大，增油减水效果明显，而当控液量达到临界值时，增油减水效果不再显著，反而趋于平缓。该综合方法的设计可节省大量的产液剖面测试成本，优化控水规模、预测增油效果，为油田提供科学的控水提液方案。
Abstract:
 High water cut is an important reason for the inefficient production in oil wells, and it is also the most important problem that restricts the efficient development of reservoirs. In actual onsite production, the analysis and calculation of production profiles and water control effects have always been a problem. In order to solve these problems, this paper, according to the commingled producing data of multiple layers and water control demand in single well, the thickness and permeability weighted method are used to determine the liquid dispensing coefficient of small layers; It is then weighted with the water saturation to determine the water distribution coefficient. Finally, the correction coefficient of the water distribution is determined by the calibration of the actual production data, thereby realizing the prediction of the production profile; According to the prediction results, a quantitative method for stratified water control effect of increasing oil production with water and liquid control has been developed. The practical application shows that the method can ensure the error of fluid production and water production for each layer within 5%, and the commingled producing error is less than 1%. For highproduction water layers, in the case of low liquid control, with the increase of the controlled liquid, the increase of oil production and water reduction are obvious, however when the controlled liquid volume reaches the critical value, the effect is no longer significant, but instead in the gentle. The integrated method can save a large amount of test cost for production profile, optimize the water control scale, predict increase effect of the oil production, and provide a scientific water control solution for the oil field.
