The study on technology to reduce fracture injury in sulige gasfleld

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.
