%X The mechanical parameters of sandstone are measured using rock physical parameter automatic testing system, made by MTS Corporation.The sandstone samples, with current burying depth of 1400 1700m, are collected from Yanchang Formation, Triassic, southwest of Shaanganning Basin. The testing formation conditions simulated include confining pressure, temperature, saturated by water, and change of the direction of samples. By means of the measurement, the poissons ratio, elastic modules and compressive strength of this stratum and this region under different formation conditions are obtained. The relatonship between confining pressure and elastic modules, poissons radio and compressive strength of the rocks in different directions and from different wells are also abtained. The mechanical parameters of samples saturated by water are compared with those of airdried samples, providing some basic parameters under formation conditions for this region.
