Method and terminal device for volume fraction prediction of dissolved gas in oil

摘要

The present invention is applicable to the field of dissolved gas monitoring technology, and provides a method and a terminal device for predicting the volume fraction of dissolved gas in water. The method includes acquiring volume fractions of gas components in the gas chamber at first, second, and third time points of the non-equilibrium state, respectively; And calculating the volume fraction of the gas component in the equilibrium gas chamber according to the volume fraction corresponding to the first time point, the volume fraction corresponding to the second time point, the volume fraction corresponding to the third time point, and the volume fraction prediction formula. It includes a step. The present invention can predict the final value of the gas component volume fraction in the gas chamber in equilibrium based on the volume fraction of the gas component collected several times in the non-equilibrium state, and before penetration is measured before measuring the volume fraction of the gas in the gas chamber. There is no need to wait to enter equilibrium, which reduces the time required to measure the volume fraction of dissolved gas in oil.
