Solid Control & Drilling Waste Management Solution

The use of earthen or lined pits is integral to drilling waste management. During most China  drilling operations, the drilling cuttings separated by the shale shaker are sent to a pit called the reserve pit located near the drill rig. The pit is generally open to the atmosphere, so it also accumulates stormwater and washwater from the rig. The strategic location of small pits near drilling sites can also help minimize spillage of drilling waste. Unless site characteristics are such that no significant threat to water resources can occur, liners are generally required. Where pits must be constructed adjacent to water bodies or on sloping terrain, engineering precautions incorporated into the design will help to ensure pit integrity. Precautions should be taken to prevent disposal of chemicals, refuse, debris, or other materials not intended for pit disposal. At the end of the drilling job, any hydrocarbon products floating on top of the pits are recovered and any free wat

Drilling mud recovery Most OBM drilling mud is disposed once drilling work finished. In contrast, much oil-based drilling mud and synthetic-based drilling mud is recycled possible. Sometimes the physical and chemical properties of the used drilling mud have degraded somewhat, and the drilling mud must be processed to rejuvenate the necessary properties. In other cases, drilling mud have been degraded sufficiently that it cannot economically be reused as new drilling mud. There are many relatively simple processes that can be used on drilling rigs to capture clean drilling mud that would otherwise be discarded and return for reuse. Like pipe wipers, mud buckets, and vacuuming of spills on the rig floor. Recovery of mud during tank cleaning may also allow the mud to be reused. Solids control equipment, like centrifuges, can be used to remove solids from the recirculating mud stream. Some new drilling mud formulations are designed to aid vegetative growth so that

During oil & gas exploration and production, there are lots of drilling cuttings  and fluid  generated. These drilling waste will leak into earth with time going which is great harm to surface and ground water and the surrounding environment even causes pollution, especially in sensitive area harmful to human health and life. Therefore, it is crucial important to drilling waste management before discharged. Here is a simple processing procedure for drilling waste management. The screw conveyor mounted under the shale shaker is used for collecting drilling cuttings from shale shakers and mud cleaners (desander or desilter), then convey the drilling cuttings to the H-G dryer for solid-liquid drilling waste management . There is one conical buried tank under the shale shakers for discharging mud and alleviate the grit in mud tank. Otherwise, if serious grouting off happened, the overflow mud will enter into the conical buries tank to prevent mud grounding. There i

Drilling waste separation  from the mud at the shale shakers may be coated with so much mud that they are unsuitable for the drilling mud recycle or disposal step or are difficult to handle or transport. Constituents of the drilling cuttings or the mud coating them, like oil or metals, may leach from the drilling waste, making them unsuitable for land application or burial requirements. Kinds of materials can be added to drilling cuttings to solidify and stabilize them. Solidification is a technology that encapsulate the drilling waste in a monolithic solid of high structural integrity. The encapsulation may be of fine drilling waste particles or of a large block or container of drilling cuttings. Solidification does not necessarily involve a chemical interaction between the drilling waste separation and the solidifying reagents but may mechanically bind the drilling waste into the monolith. Contaminant migration is restricted by vastly decreasing the surface area exp

As the drill bit grinds downward through the rock layers, it generates large amounts of ground-up rock known as drill ing waste . The conventional process of drilling oil and gas wells uses a rotary drill bit that is lubricated by drilling fluids or mud. This section discusses several alternative drilling practices that result in a lower volume of drilling waste  generated. Usually wells are not drilled from top to bottom at the same diameter, but rather in a series of progressively smaller-diameter intervals. Oil and gas wells are constructed with multiple layers of pipe known as casing. The top interval is drilled starting at the surface and has the largest diameter hole with large quantity of  drill ing waste . Drill bits are available in many sizes to drill different diameter holes. The hole diameter can be 20" or larger for the uppermost sections of the well, followed by different combinations of progressively smaller diameters. Once a suitable depth has been rea

Drilling waste is unavoidable consequence during  drilling operations. If the  drilling fluid  does not carry cuttings and cavings to the surface, the rig either is not “making hole” or soon will be stuck in the hole it is making. The drill ing   waste  that are separated from the drilling fluid on the surface by the s olids  control equipment  and some quantity of unrecoverable or economically unwanted drilling fluid are a major source of drilling waste. Drilled and formation solids that are sized smaller than can be removed by s olids  control equipment are often reported as drill solids. Some quantity of drill solids will accumulate in the drilling fluid and must be removed by the s olids  control equipment or reduced in concentration by dilution . Before the introduction of mechanical solids   removal equipment, dilution was used to control solids content in the drilling waste management . The typical dilution procedure calls for dumping a portion of the active drilling  

2 D rilling waste treating non-landing target processing technology  theory 2.1 N on-landing t echnology theory The basic theory of “drilling waste treating non-landing target processing technology” is attenuation, flocculation and separation into three parts drilling cuttings, mud clay and fluid. That’s to say, through watering and flocculation separation and chemical reaction processing to let the drilling cuttings and mud clay reaching to discharge standard. The harmful elements and chloride ion is analyzed into water, and then formed into mud clay by vac-sorb or extrusion as well as realized useful fluid recovery. The whole craft contains three processing units. The first processing unit: complete collecting drilling waste mud and fluid. First separating the rocks and cuttings from the collected mud thorough sand-water separation-washing-agitating equipment for agitating washing and spiral separation to release or reduce the influence of such kinds of material to subs
