【摘要】 天然裂缝对储层压裂效果及储层的产液量有着明显的控制作用。利用声电成像测井资料,结合常规测井资料,对裂缝发育位置、裂缝类型等裂缝特征进行了分析,对储层裂缝类型与储层改造方式及效果进行了研究。认为针对不同储层裂缝类型应采取不同的压裂方式才能达到最好的产能效果。更多还原

【Abstract】 Low-permeability reservoir has low natural productivity.Fracturing is an important means to improve reservoir permeability for the low-permeability oilfield.The existence of natural fractures has a significant influence on reservoir fracturing effect and the amount of produced fluid.Analyzed are the fracture locations,fracture types and the characteristics of the cracks by using the acoustic and electromagnetic imaging data and the conventional logging data.Studied are the type of reservoir fractures,reservoir transformation methods and its effect.Improving the reservoir productivity,different fracturing methods should be used for different types of the fractures.更多还原
