Abstract: |
A new computational formula was deduced and created to calculate oil content in water-bearing medium through introducing oil dying loss ratio. The results show that this improved fonnula can measure dry medium solid mass and oil content in petroleum-contaminated water-bearing medium accurately. Hie value of oil drying loss ratio varies depending on types of oil and water-bearing media. The oil drying loss ratio in coarse sand contaminated by diesel oil is 0.66. The relative error of the new method is about 0.4%,which is far below the relative error of existing methods. Moreover, the measurement accuracy of the new method is not influenced by oil volatility and oil content. |
