Abstract
The utility model provides complete equipment for treating oil field ageing oil for treating the recovered ageing oil which can proceed the electric dehydration. The utility model comprises a recovered oil input pipe and a medicine pot which is connected with a medicine adding pump whose outlet is communicated with a recovered oil output pipe through a pipe. The end of the recovered oil input pipe is connected with a heating stove whose outlet is connected with a cyclone through the pipe. The outlet of the cyclone is connected with a recovered oil output valve (14) through the pipe. The bottom of the cyclone is provided with a sand stacking bucket which is arranged in a sewage pot whose outlet is connected with a sewage pump. The outlet of the sewage pump is connected with the recovered oil output valve (14). Because the utility model is provided with a medicine adding pot, the heating stove, a filter and the cyclone, the ageing oil can be effectively processed. Thus, the ageing oil can proceed the electric dehydration.
Description
Technical field: the utility model relates to a kind of oil field ageing oil and is processed into covering device.
Background technology: at present, the electrical dehydrator in the crude oil dewatering system operates steadily in the ordinary course of things, but is receiving under the oil condition, and trip phenomenon often appears in electrical dehydrator.Electrical dehydrator collapses behind the electric field, the crude oil in the electrical dehydrator all need be entered emergency storage tank, electric field is recovered after adding fresh crude oil again.Here in fact said " receiving oil " be meant that these ageing oils mainly contain three sources from the ageing oil of crude oil and the different links recovery of Sewage treatment systems: the one, and the oil slick on sewage slurry tank top in the dehydration petroleum transferring station; The 2nd, the sump oil that reclaims through the sewage pond for recovering in the sewage works, the 3rd, the ground crude oil of wellsite operation.
These ageing oils have following character:
(1) long-term exposure is in air, and the light component in Sweet natural gas and the crude oil is all volatilizations, and heavy component has overwhelming superiority, so density is bigger, and viscosity is higher.
(2) long-term exposure is in air, and the part oil component has been oxidized to complicated oxide compound, and the heavy component in these oxide compounds and the crude oil has constituted emulsifying agent jointly as colloid, bituminous matter etc., makes ageing oil can form stable milk sap.
(3) contain a large amount of mechanical impuritys in ageing oil, content is between 0.5% to 1.5%.These mechanical impurity particle diameters account for 10% less than 3.97um's, and particle diameter accounts for 50% less than 112.84um's, and particle diameter accounts for 90% less than 332.38um's.These fine particles are stablizers of ageing oil milk sap, make it more stable.
(4) in the mechanical impurity that ageing oil contains, total iron content accounts for 10～20%, also has other conductive ions, and this conductive capability that makes ageing oil is much larger than ordinary crude oils.
The utility model content: the technical problems to be solved in the utility model provides a kind of ageing oil to recovery and handles, and makes its oil field ageing oil that can carry out electro-dewatering be processed into covering device.Technical scheme: a kind of oil field ageing oil is processed into covering device, has the refiltered oil input tube, it is characterized in that: also have medicinal cupping, medicinal cupping connects dosing pump, the dosing pump outlet is communicated with the refiltered oil output tube through pipe, refiltered oil input tube end connects process furnace, and the outlet of process furnace connects swirler through pipe, and the outlet of swirler connects refiltered oil delivery valve (14) through pipe; Be provided with long-pending sand hopper below the swirler, long-pending sand hopper places in the sewage jar, and the outlet of sewage jar connects sump pump, and the sump pump outlet connects refiltered oil delivery valve (14) through pipe.Beneficial effect: owing to the utlity model has grug feeding jar, process furnace, strainer, hydrocyclone structure, can effectively handle, make it can carry out electro-dewatering to ageing oil.
Description of drawings:
Accompanying drawing is the utility model structural representation;
Embodiment: have refiltered oil input tube 1, also has medicinal cupping 2, medicinal cupping connects dosing pump 3, the dosing pump outlet is communicated with refiltered oil input tube 1 through pipe, refiltered oil input tube end connects process furnace 4, the outlet of process furnace connects swirler through pipe, and swirler has two, and the import and export total pressure head of secondary hydrocyclone is not more than 0.3MPa.The outlet of swirler 5 connects swirler 6 through pipe, and the outlet one tunnel of swirler 6 connects refiltered oil delivery valve 14 through pipe, valve 13, and another road connects refiltered oil delivery valve 14 through filter 7, and the inlet outlet pressure differential of strainer is not more than 0.3MPa, and filtering accuracy is 25um.Be provided with long-pending sand hopper 8 below the swirler, long-pending sand hopper places in the sewage jar 9, and the outlet of sewage jar connects sump pump 10, and the sump pump outlet connects refiltered oil delivery valve 14 through pipe.The sump pump outlet also is connected with the refiltered oil input tube through pipe, and sand pump 11 runs in the bottom of sewage jar.During enforcement, the device of heating and dosing function can be contained on the prying body, and the device of eddy flow and filtering function can be contained on the prying body.
The on-the-spot ageing oil in oil field enters and enters process furnace 4 after topping-up pump 12 boosts, and will be stored in medicament in the pharmacy jar by dosing pump 3 simultaneously, and amount is on request injected refiltered oil input tube 1.Ageing oil enters one-level hydrocyclone 5 behind process furnace 4 internal heating, isolated solid impurity and water enter in the long-pending sand hopper 8 in the sewage jar 9 by underflow opening, water from long-pending sand hopper upper edge overflow to sewage jar 9; The sump oil that solids content is lower enters secondary hydrocyclone 6 by overflow port.Carry out oily water separation in secondary hydrocyclone 6, water-bed head piece enters in the long-pending sand hopper 8 in the sewage jar 9, plays the effect of washed-out sand, then from long-pending sand hopper upper edge overflow to sewage jar 9; Crude oil comes out from overflow port, enters dewatering system through valve 14 again after filtering through filter 7.After crude oil comes out from overflow port, also can be through valve 13 and valve 14 direct dewatering systems.Sewage in the sewage jar 9 enters sump pump 10 and boosts, and the back part of boosting enters dewatering system through valve 14, and a part is returned and mixed to ageing oil, plays the effect of dilution and heat exchange.Sand and mud in the long-pending sand hopper 8 enter sediment outflow pump 11 through valve, enter through valve 15 and draw the sand car, efflux then.
