Abstract
The present invention relates to technical field of oil production engineering, belong to a kind of ceramic plated layer airlock-resistant oil pump pump barrel processing technology driven suitable for CO2. The present invention extends airlock-resistant oil pump service life and designs to solve airlock-resistant oil pump pump barrel inner wall corrosion and serious wear in the CO2 displacement of reservoir oil well of high gas-liquid ratio. It is realized by the way that the ceramic powders of 2 inner wall of airlock-resistant oil pump pump barrel are carried out centrifugation self-propagating high-temperature technique, ceramic powders in pump barrel 2 are under high temperature fused state, the compound pump barrel 2 for being formed on 2 inner wall of pump barrel and having ceramic-lined 3 is thrown to by centrifuge, after whole cooling, to spread out mill by the grinding machine that spreads out, is bulk ceramics thickness of coating 3
Mm, hardness HV1200 or more, wearability, anti-tartar and good corrosion resistance. Present invention is mainly used for CO2 to drive in high gas-liquid ratio oil well, has many advantages, such as that wear-resisting anti-tartar is corrosion-resistant.
Description
Technical field
The present invention relates to technical field of oil production engineering, belong to one and be applicable to CO
2the ceramic plated layer airlock-resistant oil pump pump barrel processing technology of driving.
Background technology
Airlock-resistant oil pump is applicable to CO at present
2drive the good artificial lifting way of high gas-liquid ratio oil well, but due to CO
2in displacement of reservoir oil well shaft, medium mostly is containing sand, the corrosion containing dirt and in faintly acid, is in for a long time in this media environment and its life-span is badly damaged.Airlock-resistant oil pump is primarily of lengthening short circuit, pump barrel, standing valve assembly, plunger, travelling valve assembly composition.The service life of oil well pump is determined by the durability of pump barrel-plunger pair to a great extent, and in using, the fault of 70% results from wearing and tearing, the dirt card of pump barrel-plunger pair and corrodes.CO
2common cause have a strong impact on containing sand, dirty matter, the life-span of corrosivity weak acid to pump barrel-plunger pair in driving, therefore must adopt surface peening means to increase the service life to pump barrel-plunger pair.The present invention adopts ripe centrifugal self-propagating high-temperature technique, by uniform for ceramic material self-propagating to pump barrel steel pipe inner wall, utilize wear-resisting, the antiscale of ceramic material and the characteristic such as corrosion-resistant to solve oil well pump wearing and tearing, dirt card and etching problem, extend the service life of airlock-resistant oil pump.
