Description
Technical field
The present invention relates to a kind of offshore oil exploration and exploitation environmental protection technology device, particularly a kind of oil spill skimmer that is used for the drilling fluid of offshore drilling.
Background technology
The marine eco-environment is the same with land ecological environment, is the important component part of ecological environment.In nineteen eighty-two; China national Environmental Protection Agency, National Bureau of Oceanography issue laws and regulations such as " People's Republic of China's law of marine environmental protection ", " offshore oil drilling open loop border Protection Code " in succession; Offshore drilling waste discharge rules are quite strict; Particularly the drilling well of oil-containing/completion fluid discarded object has caused home and abroad environment protection circle, petroleum industrial circle and many public's common concern to the influence of environment, and this problem at sea oil field seems particularly outstanding.These drilling fluids have satisfied the needs of offshore drilling engineering preferably; But also brought problem of environmental pollution after using to marine environment; Mainly show: (1) oil-containing rejected well drilling liquid discharge into sea, oils will be separated from rejected well drilling liquid, the floating oil slick that forms across the sea.Oil slick can cause a series of harm to marine environment: 1. oils swims in the seawater water surface and forms oil film, influences the exchange of seawater and atmosphere, reduces dissolved oxygen of seawater, causes the massive losses of marine organisms or sea fisheries; 2. oil film drifts about with sea wind, usually to bay and the drift of travelling scenery district, influences the color and the smell of seawater, thereby influences shore fishery, tourist industry and industrial and agricultural production and living water use, causes enormous economic loss or abominable social influence; 3. in oils and its catabolite, exist multiple noxious material (like benzene, polycyclic aromatic hydrocarbon etc.), by aquatile absorption, enrichment, the effect through food chain gets into human body to these materials then, is detrimental to health in seawater; 4. large-area ocean oil slick also can influence atmospheric air circulation, and the harm marine ecosystems cause the long term environmental effect that is difficult to estimate.(2) oils of not separating from rejected well drilling liquid can sink to the seabed with rejected well drilling liquid, and under the condition of seabed oxygen supply deficiency, the biodegradation of oils very slowly can remain in the seabed for a long time.Oils can cause The Long-term Effect and harm to marine environment at the extended residual in seabed, as influences the vegeto-animal growth and breeding in seabed.In addition, the oils that sinks in the rejected well drilling liquid in seabed can progressively discharge, and influences halobiontic growth and breeding, or forms oil slick and cause multiple harm.
Because the self stability and the viscosity of drilling fluid, the oil slick recovery difficult is big.Conventional Separation of Solid and Liquid recovered oil efficient is low, also can destroy drilling fluid stability and performance, and the solid-liquid separating equipment volume is bigger, is not suitable for offshore drilling platform; The spiral-flow type solid-liquid separator, volume is big, destroys property of drilling fluid during Separation of Solid and Liquid, also need further carry out water-oil separating; Electrochemical deoiling methods such as detergent, its know-why are that the water in oil slick and the drilling fluid is carried out emulsification, form the emulsion of homogeneous, and oil slick temporary transient " disappearance " and hiding is prone to cause secondary pollution to marine environment, and oil slick also reclaims.
Summary of the invention
For fear of of the pollution of oil-containing drilling fluid to the marine eco-environment; And can realize reclaiming the oils resource; The invention provides a kind of oil spill skimmer that is used for the drilling fluid of offshore drilling, through gravitational settling and the effect of coalescing medium net, the realization drilling fluid separates with oil slick.
The invention provides a kind of oil spill skimmer that is used for the drilling fluid of offshore drilling, comprise drilling fluid grit chamber, diaphragm type water pump, pvc pipe line, oil water separator, receipts oil tank and drilling fluid storage tank; The import of said drilling fluid grit chamber is connected with the outlet of drilling fluid centrifuge, and drilling fluid grit chamber top links to each other with the packaged type joint; The import of diaphragm type water pump links to each other with the pvc pipe line, at the end of pvc pipe line the packaged type joint is installed, and puts into the top of drilling fluid grit chamber, draws the drilling fluid that contains oil slick, and the outlet of diaphragm type water pump is connected with oil water separator through the pvc pipe line.
Further in the preferred said oil water separator coalescing medium net is set; Said oil water separator is a packaged type.
Further the import of preferred said oil water separator is connected through the outlet of pvc pipe line with the diaphragm type water pump.
Further preferred said oil water separator has two outlets in upper and lower, and the outlet of said top is oil-out, links to each other with the receipts oil tank through the pvc pipe line; Said lower part outlet is the drilling fluid outlet, links to each other with the drilling fluid storage tank through the pvc pipe line.
Further preferred said coalescing medium net is detachable takes out and cleans.
The present invention has following beneficial effect:
1. the oil slick rate of recovery is high, reaches more than 96%, and the oil content in the drilling fluid behind the skimming is below 100mg/L.Reclaim the oils resource, protected the marine eco-environment.
2. do not use any chemical agent; Efficiently solve the problem of environmental pollution that oil slick brought of the drilling fluid that is used for offshore drilling; Oil spill skimmer realizes that through physical actions such as gravitational settling and coalescing medium nets oil slick separates with drilling fluid, has overcome the technological deficiency of oil slick in conventional use detergent " removal " drilling fluid and potential environmental risk.
3. take up an area of little: the oil spill skimmer floor space of drilling fluid that is used for offshore drilling is little; Receive oil tank and drilling fluid storage tank and all use the offshore drilling platform existing equipment; And diaphragm type water pump and oil water separator are packaged type; After using end, it is subsequent use to take in the storing Tibetan, and at sea the offshore boring island applicability is strong.
4. simple in structure, easy to operate: apparatus of the present invention are simple in structure, and on-the-spot arrangement convenience is simple to operate, and the coalescing medium net in the oil water separator detachably cleans continued and uses.
5. economically feasible: oil spill skimmer of the present invention has significant advantage economically; Except that the disposable input buying expenses of diaphragm type water pump, pvc pipe line and oil water separator; Oil spill skimmer does not produce any expense when using, and the oil that reclaims can produce economic benefit.
