Drilling waste disposal system is also known as mud zero-discharge disposal system, cuttings disposal system, cuttings disposal system and mud disposal while drilling system. According to its USES, it is divided into water-based mud landing system and oil-based mud landing system. Its main equipment includes: shale shaker,vertical cutting dryer, drilling fluid centrifuge, screw conveyor, screw pump, etc. Xi ‘an KOSUN mud landing system can effectively control the cuttings moisture content in drilling mud, stabilize liquid performance and achieve the purpose of mud landing drying. In addition, Xi ‘an KOSUN can also customize various mud landing systems for customers according to their needs and actual conditions on site.
The KOSUN mud zero-discharge waste treatment system can recover and treat drilling fluid waste, reduce the cost of treatment, recover swimming mud or water, realize resource reuse, avoid the pollution of waste to the environment, meet the environmental protection requirements of local government regulations on waste discharge, and protect the environment.
KOSUN mud zero-discharge equipment integration is high, to meet the needs of drilling while drilling or post-drilling centralized treatment. And the mobility is strong, is the miniaturization assembly, is convenient for transportation, the operation is convenient, the processing efficiency is high. The treatment conditions are mild, the treatment cost is low, the application range is wide and economical. In addition, the system is adaptable and can handle drilling wastes under different mud systems.
KOSUN DS series cyclone desander is an economical and suitable desandersander, which is the secondary desiccator in the process of the solid control system. Solid particles between 45 and 74 microns can be separated and the treated mud can be better treated by the equipment at the lower level.
Precautions for installation of hydrocyclone desander:
The hydrocyclone desander shall be installed on the main pipe line of the water supply network and fixed on the base. Bypass shall be added between the water inlet and outlet pipes.
In order to ensure smooth water flow, a straight pipe with equal diameter to the water inlet shall be installed before the water inlet of the equipment, whose length is 10-15 times of the diameter of the water inlet.
Adequate maintenance space shall be reserved around the equipment during installation.
Open the inlet and outlet valves, close the sewage valve and bypass valve during normal operation.
According to the sediment content of the source water, discharge sand and remove pollution regularly. Open the sewage valve when discharging, and the sewage process will not affect the normal water use of the system.
Close the blowdown valve after the blowdown is over.
Close the valve at the outlet if sand discharge pressure is insufficient.
This equipment has no function of filtering impurities. If there are requirements for filtering impurities, a filter should be installed.
Horizontal directional drilling solid phase control through mud is the principle and technical method of controlling solid particles in mud. Solid control technology is used to remove harmful solids from the mud, retain useful solid phase, and meet the requirements of mud properties in the crossing process.
Horizontal directional drilling technology is a trenchless technology used for laying pipelines and cables when it is difficult to dig or when the cost of excavation is high. It has obvious advantages when oil and gas pipelines cross obstacles and important areas such as rivers, lakes, traffic arteries and railway hubs.
The HDD mud and water separation system produced by xi ‘an KOSUN can separate solids from the mud, so as to realize the recycling of mud. In practice, the company constantly optimizes the system to meet the requirements of various geological environments and various sizes of processing capacity and treatment. Our company not only manufacture separation systems, but also can do related engineering services. Can be tailored to the actual address requirements of customers, meet the use requirements.
When selecting the horizontal directional drilling solid control system, the main principles are as follows:
1. Particle type and size to be removed or suppressed;
2. Quality of mud to be maintained;
3. Size of drilling rig capacity, solid phase clearance rate and cycle rate.
Oily sludge contains a certain concentration of mineral oil components, whether into the soil, farmland, arable land, or the sea, rivers, lakes, will cause serious pollution to the ecological environment or water resources.
KOSUN follow the national policy, develop the green environmental protection to repair equipment, sludge treatment and soil vibration separation, centrifugal separation technology with fluid mechanics, solve environmental waste disposal in the process of solid liquid two phase separation problems, through the subsequent processing function, reduce the pollutant emissions, recovery of available resources and meet the requirements of environmental protection of emissions standards and local government.
KOSUN oily sludge treatment scheme one: oily sludge recovery and separation system air flotation scheme. The application of this scheme can effectively realize the separation of oil, water and mud, recover the oil products that can be used in the sludge, and use specific chemical agents to reduce the oil content of the discharged sludge, the oil content rate is at least 0.5%, and reach the environmental protection standard.
KOSUN oily sludge treatment scheme two: oily sludge skid-mounted treatment system. Based on the introduction of advanced centrifuge technology from Europe and the United Nations military manufacturing team, the system is specialized in producing high-speed horizontal screw centrifuges. With the development concept of independent research and development and introduction, the company strives to make breakthroughs in the application functions of centrifuge physics. So as to solve the problem of secondary pollution caused by chemical treatment. Company research and development of special sewage sludge, dirty oil, aging oil two phase and three phase horizontal screw centrifuge won the unprecedented good results in production practice, the various indicators are better than national standards, with special sewage sludge horizontal screw centrifuge as the core of sewage sludge treatment system is fully operational, it will reduce the labor intensity of users, reduce the production cost of using the enterprise, and can also provide cost-effective manufacturing in China for the international market.
KOSUN oily sludge treatment scheme three: thermal thermal analysis of electrical radiation treatment process. The process consists of “sludge pretreatment + thermal thermal analysis + flue gas treatment + water treatment”. In order to meet the “decrement” requirements of the factory, the scheme mainly realizes the decrement of oily sludge through the thermal analysis process of electric radiation, and the liquid phase decrement rate reaches more than 94%.
