利用测井资料计算基于三轴实验的岩石力学参数

摘要

To some extent,static rock mechanics parameters,get through triaxial test,reflect the mechanical characteristics of rock.Combing limited static parameters with logging datum,through core-homing and static-dynamic parameters transformation,the relationship between static and dynamic parameters and continuous profile of rock mechanics parameters are established.The above method has been applied to well-xx in a region.by comparison,the calculated results and experimental values have the same trend and little error.%三轴岩石力学实验得到的静态岩石力学参数较真实地反映了地层岩石机械特性。利用有限的实验数据和丰富的测井资料,经岩心归位、动静态岩石力学参数转换,建立了工区岩石力学参数的测井计算关系式,由此获得关键井的连续岩石力学参数剖面。对比发现,测井计算值与归位后的实验值具有相同变化趋势,相对误差较小,可推广应用到工区其他井。
