Oil-Based Cuttings While Drilling are a kind of oilfield drilling fluid, also known as oil-based mud, which includes water-in-oil emulsified drilling fluid with oil as continuous phase, water volume content up to 50% as dispersed phase, and emulsifier as stabilizer. Drilling fluid usually composed of diesel oil, oxidized asphalt, organic acid, alkali and other chemical agents. Oil-based drilling fluid has the advantages of high temperature resistance, salt and calcium corrosion resistance, good wellbore stability, good lubricity, and little damage to oil and gas formations. At present, it has developed into an important means for drilling high-temperature wells, deep wells and other difficult wells and various complex formations, but the preparation cost is much higher than that of water-based drilling fluids.
Oil-based cuttings treatment usually adopts a special "oil-based cuttings non-falling system". The system is composed of screw conveyor, drilling cuttings dryer, environmental protection centrifuge and other equipment. The supporting mud solids control system realizes mud treatment while drilling, replacing the traditional method of using filter press or mud pool in the past. Economical and environmental benefits are widely used in oilfield drilling.
After the oil-based drilling cuttings pass through the special oil-based mud non-falling treatment system, 40 tons of oil-based drilling cuttings can be processed per hour without adding any chemicals, and the oil-based oil content of the drilling cuttings is controlled at 5% to 8%; "No pooling", "reduction" and "zero emission" and "zero addition" requirements for farms.
GREEN company has a professional mud non-falling project, whether it is oil-based mud or water-based mud, our company can effectively deal with it. In the previous cooperation projects, we have separated harmful substances efficiently and safely according to the needs of customers. If you have needs, please
