摘　　要：水平井压裂是提高致密砂岩气藏单井产量的有效手段,准确预测压裂井的破裂压力是水力压裂成功实施的关键步骤。以苏A区块水平井为例,综合考虑多种因素产生的诱导应力场建立破裂压力计算模型,以水平井A、 B井为例验证模型的准确性,所建立模型的平均绝对误差为13.96%,能较为准确地计算破裂压力。Horizontal well fracturing is an effective means to improve the single-well production of tight sandstone gas reservoirs,and the accurate prediction of the rupture pressure of fractured wells is a key step for the successful implementation of hydraulic fracturing.The rupture pressure prediction mechanism model was established by considering the induced stress field generated by various factors with an example of A horizontal well in Su A Block,the accuracy of the mechanism model was verified by taking horizontal wells A and B as examples,and the average absolute error of the established mechanism model was 13.96%,which can be capable of calculating the rupture pressure more accurately.
