摘　　要：对低孔、低渗透层采用多脉冲加载破岩启裂技术,能够降低地层的破裂压力。在此基础上实施压裂试挤,压前酸化,砂面分层、封隔器分层的复合压裂工艺,达到了改善裂缝导流能力的目的,能够提高压裂成功率。To low porosity and low percolation penetration layers, tech of the multiple pulse loading to break rock and initiate fracture can decrease the broken pressure of objected formation. Based on that, compound fracture tech of trying to squeeze with fracture, acid treatment before fracture, separating layer by sand face or packer is put into practice which reaches the purpose of developing flowing capacity of crack and raises successful ratio of the fracture.

关 键 词：低渗透层 多脉冲加载破岩启裂 复合压裂
