摘　　要：对于致密砂岩储层的开发生产,水力压裂技术是一种行之有效的方法。储层的可压裂性是评价储层产能的重要指标。结合岩石力学实验,总结了储层的脆性、韧性和岩石破坏性质的关系;利用泥岩和储层段地应力大小差异,评价了储层压裂后裂缝纵向延伸的程度;验证了该方法在L地区致密砂岩储层的水力压裂开发中可压裂性评价的适用性。For the development and production of tight sandstone reservoirs,hydraulic fracturing technology is an effective method. Reservoir fracturing availability is an important index for evaluating reservoir production capacity. According to the rock mechanics experiments,this paper summarized the relationship between the brittleness,toughness and the destruction characteristics in rock,and evaluated the vertical extension degree of reservoir fracture after fracturing based on the geostress size differences of mudstone and reservoir section. This applicability of the new method to evaluate the fracability in the development of hydraulic fracturing of L area tight sandstone reservoirs was verified.
