Critical Bottom Hole Pressure Model for Sand Production in Horizontal Wells

通过地应力场的坐标变换,完善了不同完井方式下水平井出砂临界井底流压的计算模型,提出了具体的求解方法,以井壁稳定的实际物理意义为依据将解分为不同的情况,并选取实际地层参数对水平井出砂临界井底流压计算分析,研究结果可为油田现场生产提供参考。

Though the coordinate transform of in-situ stress field,computational models for critical bottom hole flowing pressure of sand production in horizontal wells were completed for different well completion modes and the detailed computation procedure was proposed.And the different solutions could be obtained.At the same time,the detailed computational analysis of critical bottom hole flowing pressure for sand production in horizontal wells is performed by selecting actual formation parameters.
