Abstract
The utility model relates to a spin-drying and processing device for oily drilling cuttings. The spin-drying and processing device for the oily drilling cuttings is characterized by comprising a base seat, a box body installed on the base seat, a driving motor, a lube oil pump and an oil box. A feed inlet with the oily drilling cuttings is connected with the upper portion of the box body. A solid-liquid outlet is connected with the lower portion of the box body. A differential mechanism, a barrate, a spiral body and a cooling lubrication system are arranged in the box body. The barrate is arranged in the box body in horizontal direction. A screen is arranged in the barrate in an embedded mode. A vibration isolator is arranged at the lower end of the base. The spin-drying and processing device for the oily drilling cuttings has the advantages of being capable of reducing processing amount and recycling the expensive oil base mud effectively due to the fact that rate of drilling cuttings oiliness is decreased by 5% at least, installing in well drilling waste disposal places such as a drilling platform or a land processing terminal due to the compact structure and reducing oil drilling cuttings liquid contend and processing cost by processing the oily drilling cuttings.
Description
Technical field
The utility model belongs to brill completion offal treatment field, particularly relates to a kind of oil-contained drilling cuttings and dries treating apparatus.
Background technology
In the offshore oil exploration and exploitation process, the needs such as increasing hp-ht well, ultradeep well, horizontal well use oil-base mud to carry out drillng operation, but the use of oil-base mud can bring a series of problem of environmental pollution again.Because the drilling cuttings oil content of separating from the solid-liquid of drilling-fluid circulation system can so not only cause the unnecessary waste of oil-base mud up to more than 35%, but also can increase follow-up treating capacity and relevant treatment expense.
At present, at sea bore in the completion offal treatment operation, oil-contained drilling cuttings is processed the main work pattern that reclaim at marine scene, land terminal is processed that adopts, because being mixed with a large amount of oil-base mud in the landwaste of processing through the front end solid controlling system, so can not effectively separate and increase the consumption of oil-base mud it.In addition, the collection of oil-contained drilling cuttings and transport amount are large, are transported to behind the land terminal the main mode of burning that adopts and process, and not only energy consumption is relatively high, and produces easily secondary pollution.
Summary of the invention
The utility model provides a kind of adaptation operation on the sea environment, low energy consumption, high efficiency oil-contained drilling cuttings to dry treating apparatus for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Oil-contained drilling cuttings dries treating apparatus, it is characterized in that: comprise pedestal and the casing, drive motors, grease pump and the fuel tank that are installed on the pedestal, be connected with the charging aperture of oil-contained drilling cuttings on casing top, the bottom is connected with the solid-liquid outlet opening, differential mechanism, rotary drum, conveyor screw and cooling and lubricating system are housed in the described casing, described rotary drum is installed in the casing in horizontal direction, is embedded with screen cloth in rotary drum, and described pedestal lower end is provided with vibration isolator.
The utility model can also adopt following technical scheme:
Described screen cloth adopts rectangular subulate slot structure, and gap width outwards enlarges gradually by the screen cloth inner surface, and its cross sectional shape is trapezoidal.
Described rotary drum is the circle frustoconical configuration.
Described pedestal lower end evenly is equipped with vibration isolator.
Described vibration isolator adopts tack drum type brake rubber shock absorber.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, namely adopt the rotary drum of large-diameter high-speed rotation, make it produce larger centrifugal force and act on the oil-contained drilling cuttings, utilize screen cloth that it is sieved processing.Through the oil-contained drilling cuttings after the screening, its solid portion overcomes friction with screen cloth by the component of centrifugal force own and the spirochetal thrust of differential motion in screen cloth, and along rotary drum cone barrel to mobile discharge of the large end of cone cylinder.Liquid is concentrated under Action of Gravity Field and is effluxed by the solid-liquid outlet opening, has realized drying working continuously of processing operation.After the mechanical high-speed separation, drilling cuttings oil content after the drying is minimum to reach 5%, the liquid solid content is minimum to reach 2%, the expensive oil-base mud that not only reduced the treating capacity of drilling cuttings but also effective recycling, and the drilling cuttings after further purifying can return mud circulating system and re-use.Because the utility model compact conformation, low energy consumption, high efficiency are processed the place applicable to drilling wastes such as offshore drilling platform or land processing terminals.

The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1-Fig. 6, oil-contained drilling cuttings dries treating apparatus, comprises pedestal 1 and the casing 6, drive motors 10, grease pump and the fuel tank 13 that are installed on the pedestal.Be connected with the charging aperture 7 of oil-contained drilling cuttings on casing top, the bottom is connected with solid-liquid outlet opening 8, and differential mechanism 2, rotary drum 3, conveyor screw 5 and cooling and lubricating system are housed in the described casing, and differential mechanism 2, rotary drum 3 and conveyor screw 5 rotating Vortexes also keep differential.In the present embodiment, described rotary drum is the circle frustoconical configuration, and rotary drum is installed in the casing in horizontal direction.Be embedded with screen cloth 4 in rotary drum, described pedestal lower end is provided with vibration isolator 9.In the present embodiment, described screen cloth 4 adopts rectangular subulate slot structure, and gap width outwards enlarges gradually by the screen cloth inner surface, and its cross sectional shape is trapezoidal, has self-cleaning function and is difficult for stopping up.Described pedestal lower end evenly is equipped with vibration isolator, and described vibration isolator adopts tack drum type brake rubber shock absorber.Drive motors 10 is by narrow V-belt 11 and belt pulley 12 drive shaft and differential mechanism 2, and the differential mechanism other end connects respectively rotary drum 3 and conveyor screw 5, so that High Rotation Speed power and specified differential to be provided.
Operating principle of the present utility model is:
