A large amount of statistic results of interval transit time and porosity data of sandstone reservoir in the Tertiary of Jiyang Depression showed that the relation between interval transit time and porosity of sandstone was controlled by rock structure,which was affected by diagenesis.

Seismic properties of reservoir sandstones and their implication to rock texture in the Dongying Sag,the Bohai Bay Basin

Commonly used methods to quantify or semi-quantify rock textures are estimating through naked eyes,or through visual comparison charts,dot-counting,and image analyses.

In each change trend,with the rock texture transfering gradually from grain-supporting to matrix-supporting with increasing mud and calcite cement content,the propagation of elastic wave also changed from grain-to-grain contacts to rock matrix,which resulted in the measured data illustrating extremely different tendency.
