| Abstract: | Introduces the method and procedure of the core cation-exchange capacity(CEC) measurement with spectrophotometer by the numbers.Corrects the CEC calculating formula in the oil and gas industry standard SY5395-91.Analyses the errors in the measurement,particular the slope error of the working line which is obtained from the regression of the standard solution measurement and the absorbency error due to the salinity error.Gives the method to reduce measurement error by adjusting the salinity of solution.Also calculates the uncertainty of CEC measurement. |
| Keywords: | petrophysics cation-exchange capacity measurement error analysis uncertainty |
