Vertical Cutting Dryer Play a Impartant Role in the Drilling Waste Management System

Vertical Cutting Dryer is used to convert the solid waste and liquid separation to reduce the water content in the waste and after further processing. The separation of liquid can be completely recycled. Thereby, the purpose of reducing the total waste and saving the cost of waste handling are totally coming true. At the same time, VERTI-G cuttings dryer reduces the harm to the environment. Through the Eco – the Link online tracking system, operators can real-time tracking check their waste disposal and waste processing.

Data show that the conventional approach to water quality is not up to the state’s emission requirements. Possible follow-up means there are three categories: activated carbon adsorption, strong oxidants such as redox and microelectrode. The vertical cuttings dryer improves overall cost-efficiency, producing reduced amounts of extremely dry cuttings for disposal and recovering valuable fluid for reuse. Vertical Cutting Dryer is effective with water-, oil- and synthetic-base drilling fluids.

Hi-G dryer and vertical cuttings dryer would continue with dewatering and mud/gas separator to minimize waste disposal. At last, the discharged waste would be reasonably and effectively treated by means of solidification, biodegrade, thermal desorption and cuttings re-injection.The first two methods which apply to COD values are close to the water discharge standards or the water is not the case, while high-speed vertical centrifuge of the operating costs low, wide adaptation, microelectrode redox method has practical value of the current study was not thorough enough.

Recent years, with the oil industry “going out” to accelerate the implementation of the strategy, drilling mud solids control equipment to enter the international market significantly faster, at present in many countries of the world for drilling waste disposal have very strict requirements, while China with the continuous introduction of environmental policies on environmental awareness, and DWM Solids control will place increasing demands on the drilling waste discharge requirements will become more stringent.

During the traditional drilling process, waste pit is built at the drilling site for drilling waste management. That is, drilling waste management system is discharged to the waste pit at ground level for next-stage treatment, or even directly buried. This traditional discharge mode causes serious pollution and great harm to the environment and human life; therefore, State Environmental Protection Administration of China made a formal legislation in January 2015 to put forward stricter requirements and standards for drilling waste management.

Several Processing Tips of Drilling Waste Management

Usually when we start addressing the array of drilling waste management strategies and technologies, it is important to understand the nature of drilling wastes and the process that generates the waste. Drilling fluids, solids control equipment and the drilling fluid circulation system all are critical parts of the drilling operation. Drilling fluids (sometimes call drilling mud) consist of a continuous liquid phase and additives which modify the properties of the fluid to achieve better performance. The critical functions of drilling fluid include removing cuttings from the well, maintaining wellbore stability, cooling and lubricating the bit and controlling subsurface pressure.

Once the drill cuttings are carried to the surface by the drilling fluid, they are separated from the fluid using mechanical solids control equipment. Once the drill cuttings are removed, the drilling fluid can be re-circulated down the drill pipe. Depending on the geologic formation, environment, application and well objectives, drilling fluid systems are customized to meet performance requirements.

In selecting a drilling fluid one must consider the formations that are being drilled through (e.g., whether there are unstable shale present), the wellbore complexity (e.g., whether the hole is vertical, directional or extended reach), casing design, and pore pressure analysis.While Water Based Mud maintain an important role in many drilling operations, NAFs offer a number of technical advantages over WBMs in difficult drilling situations (such as extended reach or drilling of high-temperature/high-pressure wells).

Environmental regulatory considerations play a significant role in both the selection of drilling fluids and the overall economics of drilling a well. The specific regulatory requirements of an area often dictate the technologies that can be used and what, if any, material can be discharged into the environment. This in turn, influences what and how wells can be drilled. The ability to discharge NAF cuttings significantly expands the inventory of wells that can be economically drilled in an area.

Relationship of Drilling Waste Management and the Environmental

During oil and gas exploration process, the most unwanted effect would be the deposit of drilling cuttings. Modern well drilling will produce several kinds of drilling waste, for example drilling sewage, material packages and so on. Well among them the most commonly seen would be the rock cuttings from well.

Before 1980s, drilling waste treatment is seldom considered by oil and gas operating companies; generally speaking, those drilling waste would be disposed directly to the sea when performing offshore operations; while onshore drilling waste would be buried deep under the ground. When it comes to the 1980s and 1990s, as the environment protection concept is spreading all over the world, oil and gas industry operators as well as their supervisors have just began to realize the potential effect of drilling waste to the ambient environment, and as time goes by, more light is shed on drilling waste management issues.

Decades before people may think that it is difficult to drill horizontal wells, while as the new drilling technologies develops, horizontal direct drilling has attracted people’s attention. By directional well drilling and multi-branch well drilling on the same platform, the economical efficiency can be improved greatly. All the new processes have decreased the occupying area while reduced well construction cost and material assumption.

Also the production rate of single well is improved. The wide spread of environmental concepts, newly released emission standards and gradually increasing well drilling conditions have pushed oil and gas industry operators to develop more and more new compatible drilling fluids and drilling waste management techniques. Those drilling waste management techniques shall be applied to enhance environment protection work. Also recycling of drilling fluids especially the expensive oil base drilling fluid can effectively reduce drilling waste and drilling cost. As the application of more and more green& clean techniques, the exploration of oil& gas can be more effective while it can be environment friendly as well.
