在17口油井压裂资料的基础上,用灰色关联分析法分析了影响压裂效果的主要因素,用自组织方法建立了这些因素与增油量及有效期的关系式,得到了蒙古林油区不同区块、不同压裂工艺条件下,压裂后增油量和有效期的预测公式。经验证,该公式预测准确、实用性强,可用作压前经济评价,以指导压裂选井、选层和优选压裂工艺。

Based on the fracturing data of 17 oil wells, this paper uses the grey correlation method to have analyzed the main factors influencing the fracturing effect, uses the self-organization method to have established the correlativity among these factors, Incremental oil recovery and effective period, and obtained the prediction equation of Incremental oil recovery and effective period after fracturing (adopted different fracturing technology) of different blocks in Monggulin Area. The field practice proved that the equation is accurate in prediction, practical, and can be used for economic evaluation before fracturing, so as to direct the well selection, layer selection and the fracturing technology optimization.
