摘要
随着我国陆上石油勘探程度的不断提高,单纯利用纵波信息已经很难再满足当前油气勘探的要求。笔者借鉴纵波阻抗的推导过程,对转换横波阻抗的公式进行了详细的推导,分析了转换横波阻抗公式中的关键参数,并通过转换横波阻抗以求取岩石密度,而由密度参数求取的含气饱和度可以指示储层的含气性。
With the unceasing improvement of continental oil prospecting,sole use of primary wave can no longer meet the requirement of hydrocarbon prospecting.With the help of primary wave elastic impedance,the authors carried out detailed calculation of the PS converted wave elastic impedance and then analyzed the key parameter of the PS converted wave elastic impedance formula to obtain the density,which can show the gas saturation of the reservoir.
