本文主要利用法斯特经验公式研究了声波与电阻率的互换,以互相补充某些井段的资料缺失。文中讨论了声波与感应电导的关系,由感应电导制作合成地震记录的可行性;对于全井缺少声波或电阻率曲线的井,讨论了利用声波(或电阻率)曲线得到电阻率(或声波)曲线的方法.同时,研究了利用声波资料转换的电阻率及阿尔奇公式求取地层因素及孔隙度的方法。

By using the Fausts empirical formula,the possibility of the exchange of acoustic wave and resistivity was examined. With the result obtained,the lack of information in some of the well intervals could be complemented on this account, The relaionship between the acoustic wave and the inductance conduction,the feasibility of making the synthetic seismogram by using the inductance conduction were discussed and examined. For wells lack of acoustilog or resistivity log, methods of getting the resestivity profile from the acoustilog or getting the acoustic characteristic from the resistivity log was studied. Techniques for extracting the stratigruphic parameter and porosity by the Archie’s formula and the resistivity transferred from the acoustic data were also examined.
