density logging मीनिंग इन हिंदी

उदाहरण वाक्य

1. Density logging tools contain a caesium-137 gamma ray source which irradiates the formation with 662 keV gamma rays.
2. Gas is light compared to oil causing density logging ( gamma ray emitting sensors ) based measurements to produce anomalous signals.
3. Neutron and density logging tools have different responses to the presence of gas in the formation because of differences in the physics of the measurements.
4. In a similar way to how the sonic logging tool was improved to compensate for borehole effects, density logging now conventionally uses 2 or more detectors.
5. A main complication in deriving an accurate porosity in the presence of shallow invasion comes from the fact that the neutron and density logging devices typically have different DOIs.
6. Modern density logging tools include two or three detectors, which allow compensation for some borehole effects, in particular for the presence of mud cake between the tool and the formation.
7. He also tried to invent a gravity gradiometer for rock-density logging, however his first model using mercury and oil columns in glass tubes, showed the obvious fact that any ROTATION is equivalent to a gravity gradient, and a stabilized mounting is required.
