Embodiment 1

[0016] Weight ratio: 45kg of ammonium lignosulfonate, 25kg of petroleum pitch, 10kg of solvent oil, 6kg of surfactant, 1kg of sorbitol, and 3kg of sodium sulfite. Petroleum asphalt grease Qilu petrochemical products; solvent oil Qilu petrochemical, petrochemical general plant products; anhydrous sodium sulfite, products of Shanghai Dafeng Chemical Factory, content: ≥96%, iron content ≤0.005%, water insoluble content ≤0.03% free alkali ( Take Na 2 CO 3 Total) content ≤ 0.4%. This example solvent oil uses kerosene, and lignosulfonate ammonium and surfactant all use commercially available goods. Surfactants use Tween series or Span series,

[0017] Reaction: Weigh each component according to the proportion, carry out sulfonation reaction under stirring at 90-95°C for 7-8 hours, spray granulate, and sieve to obtain a powder product. Product quality inspection (according to enterprise standards). Actually achieved: appearance of tan powder, dry base product content 95.15%, wat...

Embodiment 2

[0021] Proportion: 60kg of ammonium lignosulfonate, 40kg of petroleum pitch, 15kg of solvent oil, 8kg of surfactant, 3kg of sorbitol, and 5kg of sodium sulfite; in this example, nitro thinner is used for solvent oil, and AEO or JFC is used for surfactant.

[0022] Reaction: Weigh each component according to the proportion, sulfonate reaction at 90-100°C for 7-8 hours, spray granulate, and sieve to obtain

[0023] Powdered product. Product quality: brown powder in appearance, dry base product content 94.5%, water insoluble matter 2.5%, 1% aqueous solution pH value 9.5, moisture content 14.5%, 80-mesh sieve residue 1.0%, viscosity reduction rate 99.3%, and the rest are implemented in the same way example 1.

Embodiment 3

[0025] Proportion: 50 kg of ammonium lignosulfonate, 30 kg of petroleum pitch, 13 kg of solvent oil, 8 kg of surfactant, 2 kg of sorbitol, and 4 kg of sodium sulfite; aromatic oil is used for solvent oil in this example, and OP-30 or K12 is used for surfactant.

[0026] Reaction: Weigh each component, carry out sulfonation reaction under stirring at 95-100°C for 7-8 hours, spray granulate, and sieve to obtain a powder product.

[0027] Product quality: tan powder in appearance, dry base content 93.7%, water insoluble matter 2.1%, 1% aqueous solution pH value 9.0, moisture content 13.7%, 80-mesh sieve residue 1.4%, viscosity reduction rate 99.8%, and the rest are implemented in the same way example 1.

Abstract

The invention relates to a petroleum super active powder prepared from lignin acid amine, petrolene, solvent oil, surface active agent, sorbitol and sodium sulfite. The petroleum super active powder is a mixture prepared from the following components according to weight percentage: 45-60 percent of lignin acid amine, 25-40 percent of petrolene, 10-15 percent of solvent oil, 6-8 percent of surface active agent, 1-3 percent of sorbitol and 3-5 percent of sodium sulfite. The petroleum super active powder is physic-chemically characterized in that the power is chocolate brown, the content of a butt product is larger than or equal to 90 percent, water insoluble is less than or equal to 3 percent, the pH value of water solution of 1 percent is 8-9.5, the water content is less than or equal to 17 percent, 80-mesh screen floating is less than or equal to 2 percent, and the viscosity reduction rate is more than or equal to 99 percent. The surfactant refers to Tween series, Span series, AEO, JFC, OP-30 or K12. The solvent oil refers to kerosene, nitro thinner or aromatic oil. The petroleum super active powder is applied to viscosity reduction, condense solution, washing, cleaning, diffusion, rap solution or petrolene degradation in the petroleum exploitation. The petroleum super active powder has the advantage of high viscosity reduction rate which can be larger than or equal to 99 percent in practice and can satisfy the requirements of the oil producing operation and environment-friendly property.

Description

technical field [0001] The invention belongs to the category of viscosity reducer in petroleum oil recovery, and particularly relates to a petroleum super active powder compounded by ammonium lignosulfonate, petroleum pitch, solvent oil, surfactant, sorbitol and sodium sulfite. Background technique [0002] In the prior art oil recovery operations, it is customary to use iron-chromium salt viscosity reducer; although the effect of the iron-chromium salt viscosity reducer is good, but the chromium salt is harmful to the environment, and its use has been restricted. [0003] The market expects a new viscosity-reducing agent with high efficiency and low price, simple preparation method, easy popularization and easy implementation to come into the market. Contents of the invention [0004] The purpose of the invention of this application is to provide a new viscosity reducer which has the same effect as the iron chromium salt viscosity reducer and is environmentally friendly. ...
