Drilling Waste Management can be refered as DWM (Drilling Waste Management), it is used for taking drilling fluids from the drilling cuttings and clean the fluids for resuse. It is to maximize the recycling of drilling fluids, and minimize the drilling waste in order to save cost for operators. Huayang Oil and Gas drilling waste management system can effectively control the water content and oil content of the fluids or cuttings in the drilling mud, maximize the recycling of drilling fluids and stabilize the drilling fluids phase performance, thus achieving the purpose of drilling waste management and drilling mud recycling in environment protection and cost-effectively.
High-quality handling of drill cuttings is an important task, as environmental safety worldwide depends on it. The penetration of this substance into the water body can cause marine pollution, and it penetrates into the soil and pollutes the soil, which will destroy the nitrogen balance of the bottom soil, thereby destroying the root system of aquatic plants. This is an encroachment on the ecosystem, and it affects the life of all living things in the waters and nearby areas. Therefore, drill cuttings must be disposed of.
Usually, the common drilling fluids on drilling sites include water-based mud, oil-based mud, water-based drilling fluid is generally composed of bentonite clay (glue) and additives; , organoclay and oil-soluble chemical treatments. Oil-based mud is resistant to high temperature and salt and calcium erosion, which is conducive to wellbore stability, good lubricity and little damage to oil and gas formations, and is widely used in various drilling platforms. However, diesel oil, the base oil in oil-based mud, produces toxic aromatic hydrocarbons, and the higher the amount of aromatic hydrocarbons contained, the greater the toxicity.
For water-based mud drilling cuttings and oil-based mud drilling cuttings, there are usually different treatment methods, but drying screens are used. The main equipment for water-based mud treatment is filter press, and the main equipment for oil-based mud treatment Spin dryer.
