Abstract
The oil field ageing oil dewatering treating agent is used in dewatering petroleum ageing oil. The weight ratio of each component is as follows: alkylphenol polyoxyethylene (9) ethers: 13.25 to 13.75 percent; alkylphenol polyoxyethylene (12) ethers: 14.5 to 14.75 percent; ethylene oxide propylene oxide polyether modified dimethyl siloxane: 2.5-2.75%; octylphenol polyoxyethylene (35) ether: 6.25 to 6.5 percent. Nitric acid: 0.5-0.55%; potassium nitrate: 5.5-6.75%; ammonium nitrate: 2.75-3.0%; the balance of water, and the sum of the weight percentages of the components is one hundred percent. The effect is as follows: when the temperature of the treated aged oil is 55-60 ℃, and the addition of the treating agent is 100-120 mg/L, the water content of the treated aged crude oil is less than 3.0%, and the oil content of the sewage is less than 300 mg/L. The labor intensity of workers is reduced.
Description
Technical field
The present invention relates to petroleum industry chemical agent technical field, relate in particular to a kind of treatment agent of ageing oil dehydration, solve the treatment agent of the dehydration problem of the aging crude oil of field joint stations.
Background technology
Along with oil-field development gets into middle and high Water-cut Period, comprise the various intensified oil reduction measure sequential use of chemical flooding, it is complicated more that the character of ground extraction liquid becomes.The ageing oil that causes forming in the joint station dewatering system slurry tank is thickeied; The breaking emulsion and dewatering of ageing oil is difficulty very; It can be along with the self-cleaning oil after separating, sewage etc. get into other processing links; The havoc oil water separation process; Influence dehydrating of crude oil quality and oily water treatment effect, threaten the normal operation of extraction liquid and oily water treatment facility.
The ageing oil treatment system is all had in the big oil field of ageing oil intractability in western countries.Ageing oil after the processing gets into the processed oil system.High for asphalt content, the chemical treatment difficulty is big especially and do not have contaminated crude oil, adopts that to pave the way after the nature weathering also be a good place to go of ageing oil.
At home, the Oilfield using high temperature circulation that has constantly reclaims non-oil in water emulsion wherein, reduces the volume of ageing oil; The Oilfield using that has is ageing oil concentration method such as natural subsidence in hold-up vessel, but finally all can't break away from the puzzlement of ageing oil, and these methods only limit to the lower place of output.The oil field that also has turns back to the production separation system with ageing oil, and a part of ageing oil wherein can get into production separation water system, makes water quality deterioration, and the water quality after the deterioration is regained by the sewage oil recovery system, returns the sewage slurry tank again and causes vicious cycle.
Yang Zhong equality people is published in the aging crude oil origin cause of formation of field joint stations on 2010 the 4th phases of oil-gas field environment protection and studies a literary composition with dewatering and point out ageing oil is reclaimed processing again; Not only can make it reach the sale of dispatching from the factory of self-cleaning oil standard, can also ensure the normal operation of dewatering system simultaneously., at first aging oil composition is analyzed for this reason, and the formation reason of ageing oil is launched research, on this basis, carry out the technological assessment of chemical demulsification and oxidation to harness emulsion ageing oil dehydration.Result of study shows; Oil recovery factory, Fuyu County ageing oil water ratio average 62.2%; Emulsified state is stable; The a large amount of existence of colloid FeS particulate are major causes that ageing oil generates; Oxidation to harness emulsion is more effective for the ageing oil dehydration; Under 3% dosage, the water ratio of ageing oil can be reduced to below 5%, reaches the crude oil index of dispatching from the factory.
People such as Huang Jiaxiao are published in a preferred literary composition of the ageing oil recovery method of oil-gas field surface engineering on 2007 the 12nd phases and point out; Problem for ageing oil influence dehydration is the problem that people study always, go back up till now none fast, terms of settlement completely.Through the production operation process is groped meticulously; Adopt different receipts oil methods; Carry out scrutiny, summing up experience, utilization Mathematical Statistics Analysis principle optimizes a kind of method that discharge capacity reclaims ageing oil of controlling in proportion: i.e. the ageing oil and proportioning≤11% of defeated self-cleaning oil outward.Use after the oily method of this receipts the water trap electric field stable, not defeated outward moisturely do not exceed standard, dehydrating effect is good, and its working method is convenient feasible.
People such as Zhao Shouming are published in discussion one literary composition of the central treatment station ageing oil treatment process on 2003 the 6th phases of oil planning and design through the central treatment station ageing oil being formed the analysis of reason; Discussed the harm that ageing oil brings dehydrating of crude oil, the electroconductibility of ageing oil milk sap is apparently higher than crude oil emulsion; The particle dispersion of emulsion has big stability; Ageing oil goes back to the dehydrating of crude oil system of mixing, and will cause serious detrimentally affect to dehydrating of crude oil.Through to the ageing oil Study on Properties, the individual curing technology of several ageing oils has been proposed.
Taked different measures though colloid FeS particulate ageing oil is contained to processing in each oil field, and obtained effect preferably, the method that the different oil product in each oil field is handled differs greatly.
