Description
Technical field:
The utility model relates to drilling wastes and does not land innocuity disposal system, can carry out minimizing and harmless treatment to drilling wastes, reduces the pollution even avoided environment.Belong to petroleum and petrochemical sector environment protection and pollutant abatement technology field.
Background technology:
In petroleum prospecting, in recovery process, a large amount of drilling wastes can be produced, if and these drilling wastes remain in well site storage pool for a long time, due to seepage, the reasons such as spilling, can to underground water, the ecotope of surface water and periphery produces serious pollution, drilling wastes is one of primary pollution source of industrial gas oil, its refuse process is a great problem perplexing oil field at present, " mud that waste drilling fluids disposal produces " (refuse code 071-002-08) is listed in National Hazard refuse item in 2008 " National Hazard refuse register ", along with method Tianjin regulation of country is day by day sound, the enhancing of the raising of local government's environmental requirement and oil field environment-protection consciousness, the development of Deal With Drilling Fluid technological method is imperative.
Drilling wastes is drilling waste water, drilling fluid (drilling mud), well drilling detritus, the mixture of sump oil, it is a kind of colloidal suspension system of quite stable, containing clay, high-density weighting material, various chemical processing agent, sewage, sump oil and drilling cuttings etc., environmentally hazardous main chemical compositions has hydro carbons, salt, each base polymer, heavy metal ion, the modifiers such as the foreign material in barite and pitch, these pollutents have high chroma, high petroleum-type, high COD, high suspended matter, the characteristics such as high salinity, after a series of chemical-biological and physical action, will to soil, water quality, the environmental ecologies such as biology impact.
Drilling fluid can be divided into according to fluid medium, oil base drilling fluid, water-base drilling fluid, gaseous type drilling fluid, again in actual use, first two drilling fluid uses more, water-base drilling fluid, take water as dispersion medium, it can be divided into fresh-water drilling fluid, salt-water drilling fluid, calcium treated drilling fluid, clay-free drilling fluid and oil emulsion drilling fluid again, and its basal component is wilkinite, water and chemical processing agent; Oil base drilling fluid take diesel oil as dispersion medium, by wilkinite and chemical processing agent formulated.
At present, domestic and international drilling wastes treatment technology mainly contains: simple process discharge, the annular space injecting safe formation or well, strange land focus on, backfill, cheat interior sealing, soil cultivating, solidification, microbiological treatment etc., but substantially all there is the problem that an economic benefit and environmental benefit can not be satisfactory to both parties in these treatment processs, treatment effect is good, and cost is too high; Cost is low, environmental requirement does not reach requirement again, and such as reinjection into reservoir, this type of method of soil tilth, environmental benefit is really good, but limitation is too large, impossible penetration and promotion, simultaneously, aforesaid method has certain requirement for mud system, and the process of waste after not being suitable for all brills; Why solidification method is widely adopted at present, except the balance compared with other traditional methods on cost and effect, important factor is just the broad applicability for various discarded slurry, but this class methods floor space is large, processing cost is high, and environmental risk is still larger.
Drilling wastes of the present invention does not land the object of innocuity disposal system and is: for the disposal actuality of drilling recent years waste, in conjunction with domestic each drilling company, the investigation situation of oilfield enterprise's drilling wastes treatment facility facility, and each oilfield enterprise advocating " drilling wastes do not land process up to standard ", from environment protection, the utilization of resources, cost efficiency and sustainable development and energy-conservationly angularly to set out, develop native system and treatment process thereof, single for drilling wastes treatment process to solve, treatment effect is undesirable, secondary pollution problems, reduce processing cost to drop into, realize drilling wastes minimizing, resource utilization and innoxious object.
Summary of the invention:
Drilling wastes of the present invention does not land innocuity disposal system, it is characterized in that: it is by the storage device collecting and store pending waste liquid of drilling that drilling wastes does not land innocuity disposal system, drilling wastes is carried out the equipment for separating liquid from solid (5) of separation and culture, Sewage treatment systems (8), rotary kiln incineration innocuity disposal system (10) composition of dewatering unit (9) and final harmless treatment; Equipment for separating liquid from solid (5) by vibratory screening apparatus, sand separator, silt remover, whizzer, water extracter according to demand single or combination form; Rotary kiln incineration innocuity disposal system (10) is by feeding unit (11), rotary kiln (12), dual firing chamber (13), tornado dust collector (14), interchanger (15), quench tower (16), form except acid tower (17), absorbent charcoal adsorber (18), sack cleaner (19), chimney (20).
Innocuity disposal system is not landed according to described drilling wastes, its drilling wastes does not land innocuity disposal system, the treatment plant focusing on pattern fixed location can be built up as required, also modularization skid structural device can be fabricated to, do not land process by demand with brill, or resettlement extremely processes pendingly.
Innocuity disposal system is not landed according to described drilling wastes, its drilling wastes does not land innocuity disposal system, not only drilling wastes can be processed, other solid waste such as domestic refuse, oil garbage produced in drilling process can also be processed, also fine to the treatment effect of oily sludge.
Drilling wastes does not land innocuity disposal system and has following technical superiority:
1, process range is wide, and no matter be what type, the drilling wastes of what composition all can process.
2, without the need to stock tank etc. of dredging, economize on resources, reduce costs.
3, the thoroughly innoxious of drilling wastes can be realized.
4, this cover system, can concentrate process of founding the factory according to demand, also can be fabricated to modularization, sledge-borne type equipment, dismounting conveniently moving, can move with drilling team, realizes not landing process with brill, the dispersiveness of adaptation drilling operation and mobility.
5, automation technolo degree is high, simple to operate, and labour intensity is low, and manning is few.
6, after system process, the lime-ash of generation can be used for the utilization such as brickmaking, place mat well site, the recovering and reutilizing waste water of generation or qualified discharge, and non-secondary pollution, realizes resource utilization, reduces the energy and drops into, reach energy-conservation object.
