为了对水平井分段压裂时所使用的压裂球和球座有更为全面的了解,运用 ANSYS 软件对不同材料的压裂球和不同结构的球座进行了数值模拟分析,得出结论是:为满足压裂时对压裂球强度和密封性的要求,球座端面角度α定为20°;压裂球的壁厚对压裂球的抗压强度有重要影响,采用实心制造的碳纤维压裂球效果最好;圆弧球座比传统球座对提高压裂球抗压强度更有优势。通过压裂球的强度试验,碳纤维压裂球达到了抗压70 MPa 的设计要求,圆弧球座比传统球座更有效地提高压裂球的强度。
為瞭對水平井分段壓裂時所使用的壓裂毬和毬座有更為全麵的瞭解,運用 ANSYS 軟件對不同材料的壓裂毬和不同結構的毬座進行瞭數值模擬分析,得齣結論是:為滿足壓裂時對壓裂毬彊度和密封性的要求,毬座耑麵角度α定為20°;壓裂毬的壁厚對壓裂毬的抗壓彊度有重要影響,採用實心製造的碳纖維壓裂毬效果最好;圓弧毬座比傳統毬座對提高壓裂毬抗壓彊度更有優勢。通過壓裂毬的彊度試驗,碳纖維壓裂毬達到瞭抗壓70 MPa 的設計要求,圓弧毬座比傳統毬座更有效地提高壓裂毬的彊度。

To have a more comprehensive understanding of fracturing ball and socket when staged fracturing of horizontal wells.In this paper,the finite element analysis software ANSYS is used to take related numerical simulation analysis of different materials fracturing balls and different structures ball seat,we can get it that:to meet the strength and tightness requirements of fractu-ring ball while fracturing,ball seat face Angle alpha was set as 20°;wall thickness of fracturing ball had important effect on the compressive strength,and fracturing ball made of the manufac-tured solid carbon fiber was with best effect,and arc ball seat had more advantages to traditional ball seat to improve the compressive strength fracturing ball.By fracturing ball strength experi-ment,we can get:carbon fiber fracturing ball reached the compressive strength design of 70 MPa, and compared with traditional ball seat,arc ball seat could effectively increase the fracture strength of fracturing ball.
