Blazars are one of the most extreme classes of active galactic nucleus, with high luminosity, large amplitude and rapid variability, high and variable polarization, radio core-dominance, and apparent superluminal speeds. Their broad band emission extends from radio up to gamma-ray band, and is dominated by non-thermal process.

So supported by well core experimentation, the *** analyzed the logging response feature and mechanism of thin bed, and point out that many factors can affect the logging response of the reservoir, the main factor which mostly influence the logging response is the thickness of thin layer, and the content of carbonite have a great influence on the response of 3-porosity logging.we make use of core experimentation, combined with logging material, firstly the *** do the lithology correction and thinckness correction for resistivity curves, and based on the content of mud that derived from the core experimentation, the *** present the thickness correction model of gamma-ray logging and self-potential logging, and choose the appropriate ways to compute the carbonate content and using the value of mixed frame in order to correct the influence from the carbonite, based on this, the *** gives a effective methods to correct the thickness influence for 3-porosity logging.
