摘要
本文通过分析压裂液性及施工过程;退液、试产时期的出砂规律等。认为由于压裂砂掩埋了射孔段及以下口袋,随着地层流体的排出,沉积在井底的压裂砂被携带出来,最后提出了应对类似出砂井的措施。
This paper analyses the fracturing fluid property and construction process,the sand production law during fluid withdrawal and trial production,etc.It is considered that the fractured sand buries the perforation section and the pockets below,along with the discharge of formation fluid.The fractured sand deposited at the bottom of the well is carried out. Finally,measures to deal with similar sand production wells are put forward.
