Abstract
The present invention discloses high-pressure sealing oil. Vacuum residue is diasphaltened and refined, heavy lubricating oil obtained by dewaxing ketone-benzol is used as base oil, and the heavy lubricating oil is put in a tempering kettle, stirred and heated; additives T602, T705 are added, the mixture is stirred and heated, and then finished oil can be obtained. The high-pressure sealing oil has the advantages of pumpability, strong adhesive force, good sealing performance and pressure resistance of 70mPa, and has the functions of rust prevention and sulfur resistance. The high-pressure sealing oil can satisfy the sealing requirements of various dynamic and static tests by an oil gas well, and can also be used for sealing other mechanical parts.
Description
The present invention relates to the lubricating oil technology, specifically it relates to a kind of preparation method of high pressure seal oil.
In petroleum geology exploration exploitation, various dynamic and static tests are carried out on the stratum, record and when waiting operation, the high pressure seal oil in a kind of annular space that is filled between the metal inner pipe and the outside diameter of cable of needs.This oil product should have quite high thickness sticking power to the metallic surface, guaranteeing reliable stopping property, and must possess certain fluidity simultaneously, to guarantee the fluidic pumping power.According to market survey and data-searching, domestic still do not have this series products at present, and the required high pressure seal oil of each oil-gas field all need spend a large amount of foreign exchanges from external import.
The object of the present invention is to provide a kind of preparation method of high pressure seal, the sealing oil good airproof performance by this method is produced has certain fluidity again.
The present invention is achieved in that the vacuum residuum diasphaltene is refining, the heavy grease of benzol-kentone dewaxing gained is as base oil, puts into the mediation still, stirs and is warming up to 60 ℃～120 ℃, adds additive T602
When adding additive, continue to stir 30～90 minutes.
Owing to added additive T602, T705, make oil product have good stopping property and flowability, its anti-pressure ability reaches 70Mpa, and metal is not had corrosion, has antirust anti-sulphur ability.Can satisfy the various seal requests in the petroleum exploration and development, also can be used for the sealing at various mechanical positions simultaneously.
Embodiment 1, and 100 kilograms of heavy greases are put into the mediation still, stirs and is warming up to 60 ℃, adds 6～12% T602, adds 0.6～1.4% T705, stirs 40 minutes.
Embodiment 2, and 4000 kilograms of heavy greases are put into the mediation still, stir and are warming up to 100 ℃, add 6～12% T602, add 0.6～1.4% T705, stir 90 minutes.
Additive among above-mentioned two embodiment, all by weight percentage.
Claims (1)
- A kind of modulator approach of high pressure seal oil, be that the vacuum residuum diasphaltene is refining, the heavy grease of benzol-kentone dewaxing gained is as base oil, put into the mediation still, stirring is warming up to 60 ℃～100 ℃, add additive polymethacrylate 6～12% (weights), dinonyl naphthalene sulfonate barium 0.6～1.4% (weight), stir and got final product in 40～90 minutes.
