Embodiment Construction

[0007] The present invention will be further described below:

[0008] The oil-retarding oil-based wax remover is characterized in that the ingredients and proportioning are as follows in parts by weight:

[0009] 10-20 parts of light oil, 70-95 parts of mixed benzene, 0.1-5 parts of methanol, 0.1-1 part of water, 1-5 parts of flat plus, 10 parts of fluorine-containing surfactant -3 ~10 -5 share.

[0010] The following three options can be adopted for illustration:

[0011] The effect parameters of each scheme are as follows:

[0012] It can be seen from the ratio of the ingredients in the above table and the effect produced, that the wax remover and anti-wax agent has a fluorine-containing surfactant, which makes the product have a strong surface adsorption and a very low surface tension, resulting in an interfacial tension between the oil and the oil. It is also low, and can spread into a water film on the oil surface, which cuts off the contact between oil and air, so...

Abstract

The composition of flame retardant oil-base paraffin removing and inhibiting agent for paraffin control and removal in oil field contains light oil 10-20 portions, mixed benzene 70-95 portions, methyl alcohol 0.1-5 portions, water 0.1-1 portion, Peregal 1-5 portions and fluorosurfactant 10 to the minus third-10 to the minus fifth portion. Said paraffin removing and inhibiting agent can be formed into a spread water film on the oil surface, and so that the contact of oil with air can be completely cut off. Said paraffin removing and inhibiting agent can not be burned.

Description

(1) Technical field: [0001] The invention relates to a chemical product used for removing and preventing wax in oil fields, which belongs to oil-retarding oil-based wax removing and preventing agents. (two) background technology: [0002] The crude oil currently exploited in Daqing Oilfield has the characteristics of high wax content and high freezing point, and the wax deposition is serious. Paraffin deposition has long been a problem in oilfield production. The commonly used method is to use chemical agents to remove and prevent wax from oil wells to avoid wax deposition and wax prevention in oil wells, because the wax remover does not damage the oil layer and does not affect the production of oil wells, and the dosing process is simple and convenient. However, since most of the current wax removers use chloroform, it is easy to produce highly toxic gases and cause chlorine-containing components to enter the crude oil, so as to affect the refining of oil; in addition, thi...
