哈密地区砂岩地震波速的实验研究
The experiments on seismic velocity of sandstones in Hami
摘要
Abstract
Seismic velocity of rocks have a wide range of applications in regional tectonic research and shallow seismic exploration.Hami region is one of the important production bases for oil and gas in China,but there is no data of seismic velocity.Deep environment is simulated in laboratory and the change rule of P-and S-wave velocity which come from four groups of sandstones in Hami is studied in this paper.The result shows that the P-wave and S-wave velocity increase (or decrease) with the pressure at the logarithmic rule.The porosity of sandstone affect the rate and size of increased wave velocity.The lag effect of sandstone's wave velocity mainly in the procession that wave velocity of decompression is greater than boost when they are under the same pressure.The wave velocity with high pressure is closed to the theoretical wave velocity of space averaging models.Wave velocity data measured by experiment is consistent with the log data in Hami.Therefore it can be used as the auxiliary condition to define oil layer,water layer and dry layer.关键词
