| 摘 要： | 对采自新疆准噶尔盆地东部火烧山和北三台油田的大量岩芯样品，在多种条件下进行纵横波速度的测定，进而计算了泊松比：饱水条件下岩石的泊松比为０．２７，饱油条件下为０．２１，饱气条件下为０．１７，并运用这一参数进行了正演计算及实际资料的解释，以观察其在地震记录上的响应及应用前景。结果表明，泊松比的变化不仅能直接反映岩石孔隙中所含流体性质的不同，而且在地震记录上的响应特征也很明显。实际资料的解释表明，运用地震资料直接进行油田油层的检测是可行的。

| Abstract: | The V_p and V_s values of hundreds of core samples from the Huoshaoshan and Baisantai oil fields in the eastern Junggar basin were tested under various conditions,and the Poission's ratio was accurately calculated. The ratio is 0.27, 0.21 and 0.17 for the water-saturated, the oil-saurated and the gas-saturated rocks, respectively.These parameters were used in Zoeppritz equation to model the actual data so that seismic response could be determined as well as the possibility of application of this technique in the studied area. The results show that the change of Poission's ratio can not only directly reflect the property of the fluid in rocks, but also the seismic reponse. It is possible to detect directly oil layers in an oil field based on seismic data. |
