摘    要:在大庆油田的碳氧比能谱测井解释中,统计符合率的地层数占总测量的地层数的4.2%,即有95.8%的测量资料不能与产液数据对比为了解决这个问题,我们提出一种新的计算产能的方法。以油气层渗流力学和最优化方法建立产能预测数学模型,确定了产能预测的解释步骤。在应用本方法的9口井,统计吻合率的资料从4.2%上升到100%,产能吻合率达到88.9%。本方法的原理不仅适用于套管井的解释,而且可以推广到探井和调整井

Abstract:As to C/O log interpretation in Daqing Oilfield, the number of zones for statistics of agreement between interpretation results and well testing results (or production data) amounts to 4.2% of the total zones measured with C/O log,that is ,95.8% of the log data can not be used for the comparison with production data. To solve the problem, a new productivity prediction method is developed. A prediction mathematical model for production capacity has been set up on the basis of percolation mechanics and optimization. And the productivity prediction procedures have been defined. In 9 wells using the new method, the number of log data for the statistics mentioned above increases from 4.2% to 100% and the successful productivity prediction rate reaches to 88.9% .The principle of the new method applies not only to cased hole interpretation but also to the interpretation of exploration well and adjustment well. The method correlates the production data with log interpretation data. Thus,completely changes the traditional statistical method for log coincidence rate.
Keywords:C/O logging productivity forecast log interpretation oil and gas formation percolation mechanics optimization water out
