低电阻率油气层的发现扩大了认识油层的领域。当证实它们的电阻率有时接近于同样条件的水层,认真探讨其机理成为普遍关注的问题。尤其是我国一些含油盆地中低电阻率砂岩油气层比较普遍,进一步揭示这些问题,对于提高解释成功率有着重要的意义。伴随扫描电子显微镜和x-光衍射等技术的应用,使低电阻率油气层机理的研究有了明显的进展。
The discovery of low-resistivity reservoirs has broadened the field of understanding reservoirs. When it is confirmed that their electrical resistivity is sometimes close to that of the water under the same conditions, it is of general concern that their mechanisms be carefully explored. In particular, some low-resistivity sandstone reservoirs in some oil-bearing basins in China are relatively common. Further revealing these issues is of great significance for improving the success rate of interpretation. With the application of scanning electron microscopy and x-ray diffraction technology, the research on the mechanism of low resistivity oil and gas has made significant progress.
