Each time fill diesel oil valued1200RMB

The sane diesel oil was used during the whole 
experiment procedure.

 

2. Experiment condition:
1. The Model of the purifier: THY-210A diesel oil purifier
2. The construction site and geology keeps the same during the whole experiment--- that means water, yellow mud, and sand are excavated during the whole experiment procedure.
3. The operator is the same person during the whole experiment procedure.
4. The unified standard for each well is h41m*φ0.7m.
5. The refueling situation keeps the same: The amount and unit price for refueling keeps the same each time.


3. Experiment date
The THY-210A diesel oil purifier is installed on Mar 28, 2008, the whole experiment lasts for 35 days, actually the product was used for 25 days for 10 days no work. 2、Comparison on installation effects:

Total cost for using   oil 

6934 RMB was costed, and 34 wells was excavated

18679 RMB was costed, and 100 wells was excavated Data collected before
installing the diesel oil purifier
Oil cost for each well excavated 204 RMB

169.8 RMB

34.2 RMB was saved for
 excavating each well 

Works for each tank of diesel fuel

5.8 wells was excavated 7.05 wells was excavated 1200 RMB for each refueling

 

         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%
