四川盆地前白垩系岩石物理性质的研究

<正> 作者通过对四川盆地及其附近地区自前震旦系至侏罗系各地层岩石的密度、纵波速度、横波速度、孔隙度、磁化率、剩余磁化强度和电阻率的测定,研究本区各地质时代地层岩石的物性参数分布特征,初步探讨影响这些物性参数变化的主要因素,为本区进一步寻找和勘探石油、天然气以及区域地质的研究,提供基础资料。

Study of the physical property of the Pre-Cretaceous rocks in the Sichuan Basin

The physical property parameters of the rocks from the pre-Sinian to Jurassic in the Sichuan Basin and its neighbourhood regions are discussed. These parameters contain the compressional velocity, shear velocity, density, porosity, magnetic capacity, remanent magnetization and electrical resistivity. According to the result of determination of some physical property parameters of chief rock types in this region, the changes of the factors of the physical property parameters of some typical rocks and the physical properties distributive characteristics of the rocks in different geological periods are given in this paper.
