| 摘 要： | 对ZK03孔岩芯物性测定,获得了埤城岩群密度、磁化率、剩余磁化强度和电阻率、极化率5项物性参数。埤城岩群有较高的密度,与围岩的密度差达0.15×103 kg/m3,具有重力勘探的物性前提;埤城岩群有较高的电阻率,与部分围岩电阻率差异明显,可有条件的开展电阻率勘查工作;埤城岩群具低磁性和低电化学活动性,磁测和激电方法应慎用。

| Abstract: | Petrophysical parameters of Picheng Rock Group were obtained for the first time through measuring bore samples of ZK03 hole, which included density, susceptibility,remanent magnetization, resistivity and polarizability. The density of Picheng Rock Group is 0.15×103 kg/m3 higher than that of the surrounding rocks and makes up a precondition of gravitational exploration. Picheng Rock Group has high resistivity and show obvious resistivity difference from part of surrounding rocks, and hence resistivity exploration can be conducted under certain conditions in this area. The magnetic method and IP method must be used with care because of low magnetic properties and low electrochemical activity of Picheng Rock Group. |
