BEIJING, China -- What is zero discharge or closed loop system
Mud is called "drilling blood", a mixture of oil, water, clay and organic chemicals, oil-based mud, which can effectively reduce friction, reduce accident rates, improve wellbore quality, a large number for horizontal wells and deep construction vertical wells. The past two years, the amount of oil-based drilling crew using mud growing, growth and the attendant costs of environmental protection and other security issues are also increasingly prominent. Also, due to the lack of oil-based mud cuttings treatment equipment, drilling engineering project bidding companies in foreign countries is very passive.
The so-called drilling mud without landing craft or drilling waste disposal, is in the drilling process, changing the traditional practice of digging circulating pool, the use of technology for processing waste mud and cuttings, discharge, wastewater and sludge processing part and then recycling, reduce land use, reducing the pollution of the environment.

The benefits of zero discharge system
Threefold: First, solid waste recycling, clean production sound, meet the requirements of the circular economy and environmental protection, effectively reducing the environmental risks caused by waste drilling fluid, help protect the fragile ecological environment in Xinjiang; two, "smaller" cesspool of mud reduces the land footprint, saving some for the branch land acquisition costs; Third, the cost of waste mud curing branch mainly used for comparison, this technique has a low cost, good effect and so on. Separated by this technique discharge of cuttings can act as a paving material, soil, crop cultivation, prolapse of water can be recycled to achieve recycling, energy conservation purposes.

FD Petrol oil-based mud waste the technology works by pumping, separation, drying, mixing, stirring and other mechanical equipment, in accordance with the appropriate process for drilling downhole drilling fluid back out the liquid, solid separation and processing to meet environmental requirements under the premise, to achieve re-use of oil-based drilling fluids and silt. Test equipment does not fall slurry, solid-liquid separation can be carried out, for field treatment, centrifuged and dried, to cure and transport conditions, the filtrate is recycled after separation. The test results show that most of the liquid can be reused after treatment returned to the underground, the rest of the discharge standards.
Drilling waste management case study
Daqing oilfield OBM drilling waste management
After the waste drilling mud cuttings from the wellhead back out directly into the device through its sealing strip-type pipe - screw conveyor is transferred to the cuttings drying machine, drying machine after the high-speed rotation and mesh filtering, drying the cuttings along the majority of the other screw conveyer from the first discharge port of the sand, the remaining liquid slurry through the pump into the centrifuge, re-segmentation, finally the separated fine rock crumbs sand discharged from the second port. Meanwhile, after a mud treatment by pipeline reinjected into the mud tank again recycled. The oil content of cuttings can be reduced to 3.8% from 5.3%, 30 days out of the 90 cubic meters of debris, 18 cubic meters of mud, configure one cubic meter of oil-based mud needs about 7000 yuan and 5000 yuan diesel drugs, and 18 cubic meters of mud after about an alternative system to process 12 cubic meters of oil-based mud, it is equivalent to savings of around 30,000USD

The basic principle of this technique is diluted - flocculation - Separation of three steps, the waste rocks into the mud, the mud cake, and three parts of water, debris by washing, flocculation separation and chemical reaction process may be recycled as a paving material; slurry harmful material composition and chloride ions into the water after being analyzed, and then vacuum dehydration or extrusion methods made cake; will contain a large number of organic and inorganic impurities in the water, and by pretreatment - reverse osmosis membrane treatment to meet emission standards.
