摘　　要：压裂改造是致密砂岩气藏开发评价和增储上产必不可少的技术措施;同时压裂过程中压裂液对低孔、低渗储层往往造成伤害,苏里格气田储层的孔隙度、渗透率相对较低,应更加注重降低压裂过程中引起的伤害。因此,首先对压裂过程中引起低孔、低渗储层伤害的机理进行深入分析,然后分析相应的工艺技术措施。Fracturing is a tight sandstone gas reservoir evaluation and development of reserves and production by the technical measures necessary; At the same time ,the process of fracturing fluid fracturing of low porosity and low permeability reservoirs is often caused by injury,Sulige gas field reservoir pore,the penetration rate is relatively low,should focus more on the process of fracturing caused by reduced damage. Therefore,the article first of all, the process of fracturing caused by low porosity and low permeability reservoirs of the mechanism of injury-depth analysis, and analysis of corresponding measures of process technology.
