Description

A kind of oil field ageing oil recycling and processing device
Technical field
The present invention relates to a kind of ageing oil recycling and processing device of oilfield exploitation industry, be applicable to the various aging oil handling of land and offshore oil and gas field.
Background technology
Along with oilfield exploitation enters the middle and later periods, a large amount of reluctant ageing oils appears in each oil field, big land and offshore production platform in succession, has caused the waste of device processes capacity, brings hidden danger to system simultaneously.The ageing oil main source has three approach, the recovery sump oil of treatment systems such as sewage sedimentation, flotation, the profit transition layer in the water trap, the sump oil in the height emulsive crude oil emulsion in drilling well, operation and the transport process and the oil that lands, sewage/sump oil pond for recovering.According to above source analysis, ageing oil milk sap composition is extremely complicated, mainly comprises following characteristics:
Contain mechanical impuritys such as many clays, colloidal state FeS, mainly from the oily collection of landing of each oil field, sump oil recovery system etc., the existence of clay mineral can increase the emulsification depth that electricity takes off interior transition layer, height-increasing device electroconductibility to this part component.
The inorganic salts that water treatment system is introduced, mainly the oil slick from water treatment system reclaims, the type ageing oil has been carried the various inorganic water conditioner that adds in a large amount of water treatment systems secretly, add chemical agents such as the various sterilizations added in oil recovery, the defeated process of collection, scale inhibition, inhibiter, oil in water emulsion electroconductibility is big, particularly moisture high slightly, the ageing oil that the emulsification degree is high.
The light constituent volatilization is serious.Each elephant ageing oil is the process that long-term collection is handled again at present, this has just produced the volatilization of ageing oil light constituent, and colloid, bituminous matter component substantially exceed ordinary crude oils, adsorbs with solia particle, acting in conjunction has strengthened emulsification degree and dehydration difficulty to a greater degree in water-oil interface.
More than the problem degree difference of these problems in different ageing oils, component concentration is also different, the existence of these component characteristics can cause that self-cleaning oil is moisture to exceed standard, deviating from oil content of wastewater exceeds standard, and because ageing oil contains inorganic salt ionogen, clay etc., bring very big hidden danger for the dehydrating of crude oil treatment facility, cause that easily electricity takes off tripping operation, strides accident such as electric field, has shortened the work-ing life of equipment; A large amount of ageing oil transition layers exist in system, have wasted the useful space of treatment facility, have a strong impact on the ordinary production in oil field.
At present, the inherent ageing oil processing of industry aspect, there is not special processing unit to solve problem, more solution is to adopt back the mode of mixing processing, but this mode can not be dealt with problems at all, do not approved widely yet, it is very strong to return the contaminative of mixing ageing oil, the emulsification degree of meeting increase system crude oil, cause new electricity to take off problem, having result of study to claim back to mix aging oil mass can not surpass 10%, preferably is controlled at 5%, and this art breading efficient is very low, and mostly is ageing oil circulations in system.Patent CN200410013673.7, CN200620091934.1, CN200320126151.9 all discloses ageing oil and has handled new technology, but all rely on follow-up electro-dewatering technology, the pretreatment technology or the equipment that belong to ageing oil, only the ageing oil at certain type characteristic has proposed solution, and the ageing oil of inapplicable other component type, as high conduction high emulsibility ageing oil.
Summary of the invention
In view of These characteristics and present situation, the purpose of this invention is to provide a kind of oil field ageing oil recycling and processing device, effectively the independent system of treatment of aged oil is not relied on follow-up electro-dewatering technology fully, realize the thorough processing of crude oil, break away from of the puzzlement of each component of ageing oil original dewatering system.
For achieving the above object, technical scheme of the present invention is:
