Economic Benefit Evaluation of Drilling Waste Management
At present, more and more customers have noticed the considerable prospects of domestic oil mud sand treatment projects, and drilling chip drying machines are one of the common separation methods of many oil sand separation methods. However, what is the economic benefit of the cuttings dryer used in the recovery of waste oil-based drilling fluids?
Drilling cuttings dryer
Let’s do a simple analysis:
- The oil content of drilling cuttings in oil-based drilling fluid is generally set at 20%, and the oil content of drilling cuttings is about 10% after being dried. The processing capacity of the dryer is about 10t/h, and the 25 tons of cuttings can recover 1 ton of oil-containing impurities (the drilling cuttings density is 2.5t/m3). After purification, 0.4 tons of oil is obtained. Each ton of oil can make a profit of 15,000 yuan, 0.4t×1.5 yuan /t= 6,000 yuan.
2, the centralized construction of the factory needs 7 personnel. The annual cost of personnel is about 1 million yuan (calculated by the approximate annual income of employees), and the daily cost of each person is about 397 yuan. It costs 2,778 yuan per day for seven people.
3, the equipment depreciation fee is paid 250÷3÷12÷30≈2315 yuan/day (the total production of equipment is calculated by 2.5 million yuan). Recycling 1 ton of oil needs to pay a depreciation fee of 2315÷24×3=289 yuan. (Solid control equipment shall be depreciated in 3 years, 360 days per year)
- Site construction and leasing fee 100÷3÷12÷30=926 yuan/day. (Site construction and leasing fees are calculated at 1 million yuan)
5, equipment electricity: according to the dryer per hour to deal with oil-based drilling cuttings 10 tons, the production of 1 ton of oil products needs 2.5 hours of electricity cost of 40×2×2.5×1≈200 yuan
6, vehicle usage fee: 30 tons of vehicles cost 1200 yuan per trip, 400 yuan per ton, each production of 1 ton of oil needs to transport 25×400=1000 yuan
- Diesel and water charge 50 yuan
- The equipment maintenance cost is about 50 yuan
9, other expenses about 200 yuan, (environmental protection, fire protection, going out, outsourcing, etc.).
6000-289-200-2778-1000-50-50-200-926=507 yuan
The two drying machines can produce 6.4 tons of oil products for 8 hours a day, generating 38,400 yuan and making a profit of 3224.8 yuan
