This has to do with a variety of rock-electro parameters such as m, a, m, and b which are related to oil saturation calculation of the reservoir.

There are variant rocks in Junggar and Tarim basins,a lot of experiments have testified rock-electro parameters are very different in sandstone,conglomerate, carbonatite,volcanic rock.

The frequency dispersion of rock electrical parameters could be applied to the formation evaluation,which is the main advantage of CRL different from the conventional electrical logging.

The case indicates that elastic impedance inversion can obtain ideal inversion result and from the inverted impedance section we can extract lithologic parameters which can reflect lithology and fluid character.

Determination of rock mass parameters and application of roof bolting;

By the methods of micro-damage theory,the relations of rock mass parameters and rock parameters in experiments were obtained;it is considered that to make the micro-damage theory for determining the rock parameters possible only in condition that the crack density parameters are obtained reasonably.
