摘要
在水平井分段压裂设计中,裂缝间距的选取是一项十分重要的内容。针对目前裂缝间距选择方法不完善的问题,从极限泄油半径、产能模拟、岩石可压性、压裂工艺特点、储层厚度等方面进行了研究,得到五种优化裂缝间距的方法,可为现场应用提供理论参考。
How to select the fracture space is an important content in the design of multistage fracturing in horizontal wells.Butexisting selectionmethods of the fracture spacingare notperfect. Inthis paper,through study on ultimate drainage radius, productivity simulation, crushability of rock, characteristics of fracturing technology and reservoir thickness, five methodsfor optimizing fracture spacing were obtained,which couldprovide theoretical reference for field application.
