Abstract
A kind of processing method of chemical composite flooding ceramic anti-scaling screw pump rotor relates to the mechanical oil recovery technical field, the processing method that belongs to chemical composite flooding ceramic anti-scaling screw pump rotor the invention provides a kind of processing method that can effectively improve the chemical composite flooding ceramic anti-scaling screw pump rotor of screw pump rotor surface resistive connection dirt and abrasion resistance properties.It is by thermal spraying ceramic spraying to be carried out on the surface of screw pump rotor shell 1, the screw pump rotor after the spraying is polished and the sealing of hole processing again, finally forms ceramic screw pump rotor.It is applicable to water drive, polymer flooding and chemically composited drive produced well lifting, has to delay fouling and the wearing and tearing in the course of the work of conventional rotor, prolongs pump detection period, and advantage such as reduce production costs.
Description
Technical field
The present invention relates to the mechanical oil recovery technical field, belong to the processing method of chemical composite flooding ceramic anti-scaling screw pump rotor.
Background technique
Chemically composited technology of reservoir sweep improves one of important measures of recovery rate as the oil field, the application scale enlarges year by year.But in the mining site application process, serious scale problems has appearred in lifting equipment, thereby has brought severe bad influence for the ordinary production of oil well, causes pump detection period significantly to shorten.There is scale formation in the conventional screw pump owing to rotor in the lifting process, thereby degradation problem under load torque and current fluctuation, rotor wearing and tearing aggravation and the pump efficiency appears, when the fouling peak period, average pump detection period less than 100 days has had a strong impact on chemical combined flooding whole development effect.The present invention is by the hot-spraying technique technology, the chromium layer of conventional rotor surface is substituted with ceramic coating, utilize ceramic surface to hang down and reach resistive connection dirt and the abrasion resistance properties that the high characteristic of surface hardness improves rotor, thereby solve or delay fouling and the wearing and tearing in the course of the work of conventional rotor, prolong pump detection period.
Summary of the invention
The purpose of this invention is to provide a kind of processing method that can effectively improve the chemical composite flooding ceramic anti-scaling screw pump rotor of screw pump rotor surface resistive connection dirt and abrasion resistance properties.
The present invention is made up of following steps:
A, rust cleaning, oil removing and the sand texturing at first the screw pump rotor shell that machines carried out before the surface sprays are handled, and make its whole texturing even;
B, secondly before spraying, ceramic powder is dried, by thermal spraying ceramic spraying is carried out on the surface of screw pump rotor shell then, in spraying process, guarantee every spraying one time simultaneously, the ceramic coating deposit thickness is not less than 0.03mm, and thickness of ceramic coating increased 0.03-0.06mm than actual required thickness after spraying was finished;
C, the screw pump rotor after the spraying is carried out polishing operation, make its ceramic coating surface roughness Ra reach 0.4-0.8, carry out sealing of hole at last and handle, guarantee that its porosity ratio below 3%, finally forms ceramic screw pump rotor.
Compared with the prior art the present invention has following beneficial effect:
1), the ceramic rotor surface energy is low, antiscaling effect good; 2), ceramic coating surface hardness height, abrasion resistance properties are good; 3), except that chemical combined flooding, can also be applicable to contain tempering property medium and conventional water drive, polymer flooding lifting, enlarged the screw pump application area; 4), by improving the lifting adaptability of screw pump in chemical combined flooding, prolong pump detection period to greatest extent, reduce production costs.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Provide embodiments of the invention below in conjunction with accompanying drawing:
When a, on-the-spot this method of use,, at first the TGLB800-14 type screw pump rotor shell 1 that machines is carried out surface spraying preceding rust cleaning, oil removing and sand texturing and handle, make its whole texturing even for TGLB800-14 type screw pump.
B, secondly before spraying, ceramic powder is dried, by thermal spraying ceramic spraying is carried out on the surface of screw pump rotor shell 1 then, required thickness is 0.15mm.Every spraying is one time in spraying process, and ceramic coating 2 deposit thickness are 0.03mm, sprays altogether six times, and ceramic coating 2 thickness were 0.18mm after spraying was finished, and increased 0.03mm than actual required thickness.
C, the screw pump rotor after the spraying is carried out polishing operation, polished amount is 0.03mm, makes its ceramic coating 2 surface roughness Ra reach 0.4, and simultaneously ceramic coating 2 thickness satisfy the actual 0.15mm of requirement.Carry out sealing of hole at last and handle, guarantee that its porosity ratio is 2%, finally forms ceramic screw pump rotor.
