Abstract
The utility model discloses a pressure oil separating and sedimentation tank used in the handling technique of water pumped from an oil filed. The tank comprises a tank body, a liquid entering pipe, an oil receiving opening and a water exiting pipe. The position from the internal part at the left end of the tank body to the middle part of the tank body is orderly provided with the liquid entering pipe, an agglutination cavity, an oil separating cavity and a central water receiving cavity. The position from the internal part at the right end of the tank body to the middle part of the tank body is orderly provided with a reacting cavity, a sedimentation cavity and a final water receiving cavity. The wasted water entering the liquid entering pipe are orderly agglutinated and precipitated as well as separated so as to enable the released wasted water content contained in the oil field to reduce from 500mg per liter below 20mg per liter with floating articles removing efficiency of above 90 percent. The pressing oil separating and sedimentation tank manufactured as per the technical scheme enables a new built wasted water handling station with daily handling amount of 4 by 10 <4>m<3> to reduce the fundamental building investment by 4 million 500 thousand RMB, furthermore, the economic benefit is substantial.
Description
The utility model relates to a kind of pressure oil removing slurry tank that is used for oil field produced water treatment.
Consult the pressure oil removing slurry tank that still finds no dependency structure by retrieval.
Oil field extracted water is not only polluted by crude oil, and it has dissolved various salts and the gas in the stratum in high temperature, highly compressed oil reservoir; In oil recovery process, in oil reservoir, carry many suspended solidss; All kinds of chemical agents in the oil-gas gathering and transportation process, have been mixed into; Contain large amount of organic in the recovered water again, suitable microorganism survival environment is arranged, encouraged the breeding of bacterium.In a word, recovered water is the waste water that contains plurality of impurities.Oil field produced water technology is started in the fifties in China, the research of going through 40 years is used and development, now formed comparatively supporting technical system, but raising along with oil recovery technique, variation has taken place in the character of recovered water, particularly in recent years, adopt " three adopt engineering " for improving oil recovery factor, injected a large amount of oil-displacing agents to underground, the also corresponding oil-displacing agent composition (average polymer content reaches more than the 50mg/L in the recovered water at present) that contains in the extraction liquid, and the water quality requirement after handling has also been had large increase, this goes out water treatment just for oil field Bian and has brought new problem, new difficult point.
The present situation of each oil recovery factory's oily water treatment, problem and countermeasure and each sewage plant hay tank working condition were done investigation and analysis under Prospecting Design Inst., Shengli Petroleum Administration began Shengli Petroleum Administration Bureau in 1998, discovery as liquid-liquid, liquid-solid heterogeneous isolating extracted water deoiling, remove the most economical way of suspended substance and remain gravity method, promptly utilize the density variation of water, oil, suspended substance, make dispersed oil droplets in the water, the sedimentation of suspended substance buoyance lift and the three is separated.Liquid-the liquid of different densities difference, the separation efficiency of liquid-solid system are by " shallow pond " principle, only relevant with the buoyance lift settling area with the terminal velocity of oil droplet, solid particulate, and it is irrelevant with the buoyance lift settling height, this inclined tube swash plate treatment technology just occurred, plate distance or honeycomb diameter are more little, under identical treatment capacity, can get rid of more little oil droplet of particle diameter and solid particulate, increase the oil removing settling efficiency; Or under the condition of same treatment efficient, improve the processing power of equipment.But minification is given on the spoil disposal oil removing structure treatment again and has been brought difficulty, has limited size between further shortening plate, has just limited further raising processing efficiency.By " shallow pond " theory, another approach of strengthening the profit gravity separation is the particle diameter that increases oil droplet, has so just developed coalescence technology, is about to tiny oil droplet and adheres to coalescent peeling off on the solid matter of surperficial oleophilic drainage, formation larger oil droplet and accelerate its sepn process.
The purpose of this utility model combines coalescence technology and " shallow pond " principle exactly, has designed and developed and has gathered knot small echo plate lateral flow oil removing and eddy flow grid reaction small echo plate flocculating settling in the pressure oil removing slurry tank of one.
