PIONEER ENERGY
XRF Element Logging Instrument

Overview


  • It can be used to obtain information on element composition (component, content, and distribution rules) from rock cuttings powder obtained while drilling through the X-ray fluorescence analysis technology, identify the lithology and determine and divide the stratum through element combination characteristics, and further carry out in-depth data analysis and processing to find laws related to reservoir physical properties and oil and gas properties, thereby achieving the purpose of reservoir evaluation. 



Features

    • Providing multiple element curves in real time, as well as quantitative data and curves for field stratigraphic correlation and division; 

    • The content data of elements can truthfully reflect the material basis of rocks, which is helpful for understanding rocks and strata in essence; 

  •  In the case of logging failure due to complex well conditions, quantitative curves are required for profile recovery and stratigraphic division. Identification of special acid lithology, such as interpretation of carbonate rocks and igneous rocks.
