Embodiment 1

[0048] 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 cetyltrimethylammonium chloride, sodium carboxymethylcellulose 2 servings.

[0049] Mix the drug according to the above proportions and add it into absolute ethanol, stir it evenly, mold it, and dry it at 80°C for 48 hours to obtain a soluble chemical wax removal ball.

Embodiment 2

[0051]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 cetyltrimethylammonium chloride, cetyltrimethylammonium 7 parts of ammonium bromide, 10 parts of sodium carboxymethylcellulose, 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 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 Alkanes, fully stirred, molded with a spherical rubber mold with an inner diameter of 45mm, put it into an oven for drying at 80°C for 48 hours, and obtained soluble chemical wax removal balls.

Abstract

The invention provides a soluble chemical paraffin removal ball and a preparation method and a use method of the soluble chemical paraffin removal ball. The soluble chemical paraffin removal ball comprises the following raw materials: 60-104 parts of a surfactant and 7-27 parts of a thickener; the surfactant is one or more of sodium stearate, hexadecyl trimethyl ammonium chloride, hexadecyl trimethyl ammonium bromide, sodium laurate, octadecyl trimethyl ammonium chloride, and octadecy trimethyl ammonium bromide; the thickener comprises 2-10 parts of sodium carboxymethylcellulose, 2-10 parts ofpolyacrylamide and 2-7 parts of sodium polyphosphate. The raw materials are proportionally added into absolute ethyl alcohol, stirred evenly, formed through a mould, and dried to obtain the soluble chemical paraffin removal ball. The paraffin removal ball is added according to the conditions of the pipeline length and the paraffin precipitation. The chemical paraffin removal ball has double effects of physically removing paraffin and chemically preventing paraffin, and the problem of paraffin precipitation in a transportation pipeline of the crude oil is solved.

Description

technical field [0001] The invention belongs to the technical field of petroleum exploitation, and relates to a soluble chemical wax removal ball, a preparation method and a use method thereof. Background technique [0002] Crude oil is a typical waxy crude oil with serious wax deposition, which can easily cause oil well wax sticking, rod breakage, or even "lying well". Cause the cost of oil production to rise, and the follow-up processing problems increase. To sum up, the problem of paraffin deposition in the process of oil recovery and gathering 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 gas exploration, development and oil processing in depth, the urgency and importance of studying and solving the problem of paraffin deposition have become more ...
