Embodiment 1

[0022] a. Take the dried kelp, you can choose the dried kelp sold in the market, or dry the fresh kelp;

[0023] b. Clean the dried kelp with water to remove impurities;

[0024] c. Pulverize it with a colloid mill;

[0025] d. wash the pulverized kelp with water and separate the kelp viscous liquid with sodium hydroxide water;

[0026] e. For the biochemical treatment of kelp mucus liquid, the time and temperature can be treated with conventional biochemical conditions;

[0027] f. 50 kg of biochemically treated kelp viscous liquid, 15 kg of vitamin H, 15 kg of kerogen, and 20 kg of OP-10 emulsifier are mixed for emulsification biochemical treatment. The kerogen is a kind of oil source rock, that is, a kind of dark mudstone or shale, and the time and temperature of emulsification and biochemical treatment can also be done under conventional conditions. Its active performance index is water-wet type contact angle125°.

Embodiment 2

[0029] Others are as in Example 1, just cleaning the kelp filter residue produced by step d with ethanol, and separating the kelp mucus, mixing the kelp mucus separated by ethanol treatment with the kelp mucus liquid produced by step d, and then For the biochemical treatment of kelp mucus liquid, the time and temperature can be used under conventional biochemical conditions; take 60 kg of biochemically treated kelp mucus liquid, 10 kg of vitamin H, 15 kg of kerogen, and 25 kg of OP-10 emulsifier. Emulsion biochemical treatment. The kerogen is a kind of oil source rock, that is, a kind of dark mudstone or shale, and the time and temperature of emulsification and biochemical treatment can also be under conventional conditions. Its active performance index is water-wet type contact angle125°.

Embodiment 3

[0031] Others are as in embodiment 1 or embodiment 2, wherein the biochemical treatment of the kelp slime liquid is to biochemically treat the kelp slime liquid for 2 to 3 hours. Take 60 kg of biochemically treated kelp viscous liquid, 2 kg of vitamin H, 15 kg of kerogen, and 23 kg of OP-10 emulsifier to carry out emulsification biochemical treatment. The kerogen is a kind of oil source rock, that is, a kind of dark mudstone or shale, and the time and temperature of emulsification and biochemical treatment can also be under conventional conditions. Its active performance index is water-wet type contact angle125°.

Abstract

The invention discloses a biological viscosity-reducing agent for seatangle composed constituents with weight percent as: 50-60% biochemical seatangle viscosity liquid, 2-15% vitamin H, 3-15% kerogen, 10-25% emulsifier OP-10, with activity performance index: water wetting contact angle less than 70Deg, medium wetting 75-125Deg, and oil wetting contact angle more than 125Deg. The opposite preparation comprises: selecting dried seatangle of 50-60% full weight; cleaning, smashing; bathing with sodium hydroxide to separate seatangle viscosity; taking biochemical emulsification treatment with proper other said material. This product has well viscosity reduction effect to solve existing problem in oil refining with high economic and social benefits.

Description

Technical field: [0001] The invention relates to a viscosity reducer for reducing the viscosity of petroleum crude oil and a production method, in particular to a kelp biological viscosity reducer which can effectively reduce the viscosity of petroleum crude oil and which is applied in the processes of petroleum crude oil extraction, transportation, refining, storage, etc. production method. Background technique: [0002] We know that petroleum crude oil mostly exists in the formation in the form of heavy oil, high-viscosity heavy oil is generally above 100,000 CP, and low-viscosity heavy oil is generally between 1,000 and 2,000 CP. Because the technical conditions of oil production require that the viscosity of petroleum crude oil should be below 1000CP, people must add a large amount of viscosity reducer (surfactant) to crude oil. At present, most of the viscosity reducers used in oilfields are based on emulsifiers, with organic substances such as polyethers as the main b...
