Embodiment Construction

[0019] A kind of nanometer wax removing and preventing agent suitable for oil products with higher water content of the present invention specifically comprises the following steps:

[0020] Step 1, select the applicable traditional wax remover as raw material;

[0021] Step 2: Selecting suitable nanomaterials, adding the nanomaterials to the wax remover, determining the compounding ratio of the nanomaterials and the wax remover, and compounding them;

[0022] In the third step, the mixture obtained in the first step and the second step is granulated by a granulator, and processed into ellipsoidal or cylindrical particles;

[0023] The fourth step, the particles produced in the third step are processed into powder by freezing and pulverizing;

[0024] The fifth step, adding a suitable solvent to the product obtained in the above steps, and heating and dissolving it after adding the solvent to form a uniform solution;

[0025] The sixth step, when transported to the site fo...

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 [0001] The invention relates to an oil field chemical agent, namely a chemical agent that can be used for oil wells, natural gas wells and gathering pipelines for transporting waxy (water-containing) oil products with high water content and producing waxy crude oil and condensate oil, It can improve the crystallization and dispersion characteristics of paraffin in oil (water), improve the fluidity of oil in wellbore and pipeline, and clean, inhibit and prevent the deposition and adhesion of wax on the inner wall of the pipe. Background technique [0002] Wax remover is a chemical agent used for oil wells, gas wells, and waxy oil in gathering and transportation pipelines to dissolve paraffin that has been deposited and adhered to the inner wall of the pipe, and reduce the freezing point and viscosity of oil products. [0003] Oil-based wax remover (including wax preventive and pour point depressant) has been widely used in oil wells, natural gas wells and gath...
