Remarks |
Choose for the diesel fuel |
Choose the best one, which is 6.40yuan/L,the highest price in the domestic market |
The price keeps the same during the experiment |
Filter for the diesel fuel |
Dual filter |
|
Usage status for the diesel fuel |
Each time fill diesel oil valued1200RMB |
The same 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.
- 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.

Data uncollected for short time |
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% |
