Embodiment 1

[0048] The raw materials include: 80 parts of sodium stearate, 2 parts of polyacrylamide, 3 parts of sodium polyphosphate, 1 part of ethylenediaminetetraacetic acid, 4 parts of cetyltrimethyl ammonium chloride, sodium carboxymethyl cellulose 2 servings.

[0049] The medicines were mixed uniformly and added into absolute ethanol according to the above proportions, stirred uniformly, molded by a mold, and dried at 80° C. for 48 hours to obtain soluble chemical wax-clearing balls.

Embodiment 2

[0051]The raw materials include: 45 parts of sodium stearate, 10 parts of polyacrylamide, 7 parts of sodium polyphosphate, 3 parts of ethylenediaminetetraacetic acid, 8 parts of cetyltrimethyl ammonium chloride, cetyltrimethyl ammonium chloride 7 parts of ammonium bromide, 10 parts of sodium carboxymethyl cellulose, and 10 parts of n-docosane.

[0052] The preparation method is as follows:

[0053] Heat and dissolve n-docosane at 45°C, mix other medicines evenly in proportion, add absolute ethanol, use absolute ethanol as a solvent to dissolve sodium stearate, stir it evenly, and add it to the hot-melt n-docosane. In alkane, fully stirred, molded with a spherical rubber mold with an inner diameter of 45 mm, put it in an oven at 80° C. for drying for 48 hours, and obtained soluble chemical wax balls.

Embodiment 3

[0055] The raw materials include: 60 parts of sodium stearate, 3 parts of polyacrylamide, 2 parts of sodium polyphosphate, 8 parts of ethylenediaminetetraacetic acid, 12 parts of cetyltrimethyl ammonium chloride, cetyltrimethyl ammonium chloride 12 parts of ammonium bromide, 2 parts of sodium carboxymethyl cellulose, 1 part of n-docosane.

[0056] The preparation method is as follows:

[0057] Heat and dissolve n-docosane at 70°C, mix other medicines evenly in proportion and add absolute ethanol, use absolute ethanol as a solvent to dissolve sodium stearate, stir it evenly, and add it to the hot-melt n-docosane. In alkane, fully stirred, and molded with a spherical rubber mold with an inner diameter of 45 mm, put it in an oven at 100 °C for drying for 36 h.

Abstract

The invention provides a soluble chemical wax-clearing ball and its preparation and use methods. The soluble chemical wax-clearing ball includes the following raw materials: 60-104 parts of surfactant and 7-27 parts of thickener; the surfactant is Sodium stearate, cetyltrimethylammonium chloride, cetyltrimethylammonium bromide, sodium laurate, stearyltrimethylammonium chloride, stearyltrimethylbromide One or more types of ammonium chloride; thickeners include: 2-10 parts of sodium carboxymethylcellulose, 2-10 parts of polyacrylamide, and 2-7 parts of sodium polyphosphate. Add the raw materials into absolute ethanol according to the proportion, stir evenly, use a mold to shape, and dry to obtain soluble chemical wax clearing balls. Add the wax clearing ball according to the length of the pipeline and the wax accumulation situation. The chemical wax removal ball of the present invention has the dual functions of physical wax removal and chemical wax prevention, and can solve the problem of wax deposition in crude oil transportation pipelines.

Description

technical field [0001] The invention belongs to the technical field of petroleum exploitation, and relates to a soluble chemical wax cleaning ball and a preparation method and use method thereof. Background technique [0002] Crude oil is a typical waxy crude oil with serious wax deposition, which can easily lead to oil well wax sticking, broken rods, and even "laying wells". As a result, the cost of oil extraction increases and the follow-up processing problems increase. To sum up, paraffin deposition in the process of oil production and gathering and transportation has always seriously affected all aspects of oil production and processing. Paraffin deposition occurs in oil and gas reservoirs, production equipment, gathering and transportation pipelines, and processing equipment. In recent years, with the rapid development of oil and natural gas exploration, development and oil processing in the depth direction, the urgency and importance of researching and solving the pro...
