Abstract

The invention relates to a water-quality conditioner and a preparation method thereof. The water-quality conditioner is an aqueous solution of 25%-35% (by concentration) sodium hydroxide, wherein the aqueous solution comprises the following components in parts by mass: 1680-2520 parts of water and 720-1,080 parts of sodium hydroxide. The preparation method comprises the following steps of weighting each component in parts by mass and separately placing for later use; adding 65%-75% of the mass of clean water in a mixer, starting stirring for 3-5 minutes at a stirring speed of 100-150R / min; adding sodium hydroxide in a mixer, and starting stirring for 18-22 minutes at the stirring speed of 100-150R / min; and continuously adding sodium hydroxide in the mixer and simultaneously adding the residual clean water, starting stirring for at least 20 minutes at the stirring speed of 100-150R / min and stopping stirring until the chemical agent is uniformly mixed. By the product, the produced water can have same properties as those of formation water, the water-quality conditioner has good compatibility, the phenomena of scaling and blockage of the formation can be avoided and the production rate of crude oil in the oil field is ensured; and the product is produced by adding water, the heat is generated, the temperature is about 80 degrees and the product is relatively safe.

Description

technical field [0001] The invention belongs to the technical field of stabilizers, in particular to a water conditioner and a preparation method. Background technique [0002] In the process of oilfield sewage treatment, due to the treatment of oil removal, heating, sedimentation, and addition of chemical agents, the produced water has poor compatibility with formation sewage, which will lead to formation pollution and formation clogging, formation pollution and After clogging, the crude oil production will be reduced, and serious fouling will be caused.
