Abstract: Rock mechanical properties are the essential parameters in the application of petroleum engineering and they could be obtained through laboratory experiment under simulated strata conditions. These measured properties are only for certain formations, so continuous formation properties used in strata engineering are usually from logging data. Nevertheless, result discrepancy exists between these two different methods due to the difference of loading frequency and only could those obtained from logging be applied in petroleum engineering after certain calibration. To obtain calibrated continuous logging data from laboratory tests, static and dynamic properties of formation rock under simulated strata condition were primarily studied.

Key words: in-situ stress, mechanical property of rock, ultrasonic wave velocity, experimental study
