选取某油田某区块为试验区,应用灰色关联方法分析影响压裂效果的主要因素,分别采用均值变换和极差变换方法对样本库的16口井的日增油量进行预测,并通过多元回归方法建立预测模型,预测结果显示极差变换方法预测结果较为准确,预测井的绝对误差平均值为0.52 t/d,能够满足现场压裂工艺的实施要求.
A block of a certain oilfield is selected as the experimental area, and the main factors affecting the fracturing effect are analyzed by the gray relational method. The average daily oil yield of 16 wells in the sample reservoir is predicted by means of average transformation and range difference transformation respectively. Regression method to establish the prediction model, the prediction results show that the prediction method of the range difference transformation method is more accurate, and the average absolute error of the prediction wells is 0.52 t / d, which can meet the implementation requirements of the field fracturing technology.
