Description
Technical field
The utility model relates to sewage treatment area, the water treatment facilities that particularly a kind of skid-mounted type can automatic backwash Oil/gas Well output water.
Background technology
Oil/gas Well output water source is very extensive at present, mainly returns the aspect such as water outlet, well-flushing waste water from techniques such as output water, fracture acidizings in Oil/gas Well production process.Along with the raising of oil gas field recovery percent of reserves, reservoir formation pressure drop on the one hand, stratum energy deficit progressively increases, and need to adopt the mode such as makeup energy, volume increase transformation further to improve recovery ratio; Formation water is constantly invaded oil reservoir on the other hand, and producing well moisture content increases, and has increased the pressure of ground sewage processing, and this is the Universal Problems that domestic each oil gas field runs into.
Oilfield sewage often has all kinds of materials of pollution to environment containing solid impurity, crude oil, dissolved gas and soluble salts etc., must carry out after specific aim processing, could normally discharge.The method of processing oilfield sewage has conventionally: Physical, physical-chemical process, chemical demulsification method, biochemical process and electrochemical process.Because each field produces situation difference, output formation water character are different, processing method and fund input be also not quite similar, therefore wastewater treatment efficiency just has difference.At present, the water treatment of the Oil/gas Well output water Sewage Disposal modes of setting up of concentrating that adopt mostly more, if while processing local sewage far away or need to connect longer sewage pipe or adopt long distance transportation mode, therefore there is the shortcoming that the poor cost of mobility is higher, water treatment efficiency is poor.
The water treatment facilities of Oil/gas Well output water can meet the requirement of effluent quality at initial operating stage, but after a filter cycle of operation, because its holding filth capacity is larger, may cause filter clogging, and along with the prolongation of time, effluent quality worse and worse.Because the water treatment facilities of Oil/gas Well output water adopts to dirty more, the initial stage of filtering, filtrate is cleaner, porosity is larger, and along with the prolongation of filtration time, in filtering layer, impurity increases gradually, flow shear increases gradually, so suspended particulate just moves to lower floor in sewage, lower floor's filtrate crown_interception is difficult to performance filtration just to be stopped, and causes the problems such as water treatment efficiency is low, operating difficulties.Now need filtrate to carry out backwash.
At present, the water treatment of the Oil/gas Well output water Sewage Disposal modes of setting up of concentrating that adopt mostly more, if need to connect longer sewage pipe while processing the sewage in place far away or adopt long distance transportation mode, therefore having the shortcoming that the poor cost of mobility is higher, treatment effeciency is poor.Owing to needing a large amount of clear water to be recycled in oilbearing stratum in oil recovery process, if recovered water is carried out to in-situ processing, and for re-injection, not only can meet the growing needs of water injection rate in oil exploitation process, can save great lot of water resources simultaneously, for bringing economic benefit in oil field, and reduce the pollution of sewage effluent to environment, can produce huge environmental benefit.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and the water treatment facilities that a kind of oil removal efficiency is high, mobility is high skid-mounted type can automatic backwash Oil/gas Well output water is provided.
