3. Analysis on economic efficiencies:
The experiment shows “Janenope” diesel oil purifier has the effects of prolonging the service life for engine, reducing the maintenance cost, extending the maintenance cycle, purifying tail gas and saving oil.
For oil-saving, take the oil cost for excavating each well to calculate, results is below: Each well saves oil cost 34.2 RMB, and it should have cost 204 RMB in the past.
Oil-saving rate: 16.76%
