Abstract
The invention discloses a nanometer paraffin removal and inhibition agent for a high-water content oil product. A preparation method of the nanometer paraffin removal and inhibition agent comprises selecting an appropriate traditional paraffin removal and inhibition agent, selecting an appropriate nano-material, determining a mixing ratio of the paraffin removal and inhibition agent to the nano-material, processing the materials to form axiolitic or cylindrical particles or carrying out refrigeration crushing to obtain powder, selecting an appropriate dispersant, cosolvent and stabilizing agent, carrying out heating dissolution to obtain a uniform solution, transporting the solution to a place, and in necessity, forming a high-liquidity uniform liquid by heating and thermal insulation. The nanometer paraffin removal and inhibition agent can reduce a wax precipitation point of oil wells, gas wells and gathering and transportation pipes with high water content and reduces oil product viscosity and condensation point. When the addition amount is higher than a certain value (ppm), paraffin inhibition efficiency is generally 40% or more and paraffin removal effects are obvious. The nanometer paraffin removal and inhibition agent can prolong an oil well hot washing period, has effects of demulsification and viscosity reduction, and can be used as a well washing solution and a viscosity reducer.
Description
Technical field
The present invention relates to a kind of Oilfield Chemicals, namely a kind of can be used for water content higher, the chemical agent of the gathering line of oil well, gasser and the conveying content of wax (moisture) oil product of producing waxy crude oil and condensate oil, the crystallization of paraffin in oil product (moisture), dispersing characteristic can be improved, improve the mobility of oil product in pit shaft and pipeline, clear up, suppress and prevent wax in the deposition of inside pipe wall and attachment.
Background technology
Wax removing agent is for oil well, gas well, the content of wax oil product of gathering line, dissolves the stone wax already having deposited and be attached to inside pipe wall, reduces a kind of chemical agent of oil product condensation point, viscosity.
Oil base wax removing agent (comprising Wax coagulation preventing agent), has been widely used on oil well, gasser and gathering line.But because medicament is to the susceptibility of water-content, make still there is many problems on effect.Such as when water content is higher, the medicament of this kind of oil base is just difficult to play wax removal effect, and wax control result is also undesirable.
In recent years, along with the widespread use of nano material in oilfield chemistry, nano material is combined with traditional wax removing agent, be equipped with other auxiliary agents suitable and solvent again, the result of use of this kind of medicament under the higher operating mode of water content can be improved significantly, promote economic benefit and the safety assurance of user.
Summary of the invention
Technical problem to be solved by this invention is, there is provided a kind of can be used for water content higher, the chemical agent of the gathering line of oil well, gasser and the conveying content of wax (moisture) oil product of producing waxy crude oil and condensate oil, the crystallization of paraffin in oil product (moisture), dispersing characteristic can be improved, improve the mobility of oil product in pit shaft and pipeline, clear up, suppress and prevent wax the deposition of inside pipe wall and attachment, the nanometer wax removing agent that is applicable to the higher oil product of water content.
The present invention is achieved through the following technical solutions: a kind of nanometer wax removing agent being applicable to the higher oil product of water content, specifically comprises following step:
Traditional wax removing agent that step one, selection are suitable for is as raw material;
