摘要
压裂施工中暂堵剂用量合理与否,是决定选择性压裂和多裂缝压裂工艺成败的技术关键,同时也直接影响压裂井改造效果。针对目前现场中应用的计算方法、存在问题等进行了客观分析,并提出了新的计算方法,解决了原计算方法求出的暂堵剂用量普遍偏大的问题。新的计算方法达到既能堵注预暂堵层、压开新缝,又不浪费暂堵剂、节约成本,对指导压裂施工具有重要意义。
Temporary blocking agent dosage in fracturing treatment is key to the selective fracturing treatment and multi-fracturing treatment in terms of technology,Meanwhile it affects the adjustment of fractured well.On the basis of previous calculation method and the analysis of existing problems,a new calculation method is brought forward to prevent the excessive dosage of temporary blocking agent calculated with previous method.The operation with calculated temporary blocking agent dosage not only temporarily blocks the formation and shapes new fractures,but also avoids temporary blocking agent waste and saves operation cost.The new calculation method is significant in assisting fracturing operation.
