First, the use of products
Multiple solid acid KD-52 is prepared by a variety of organic acids. Mainly used for operations in the wellbore cleaning and descaling, nearly stratum well solution blocking, water injection pipeline and pipeline cleaning, with better yield increasing effect of injection, and has good retarding effect, can reduce the damage to formation and the pipeline.

Two, technical requirements

 

Project		Index

10%Aqueous solution	pH	2～4
	Soluble calcium content，g/100ml	≥4.0

Three, the use of methods
For shaft cleaning, generally formulated as 8-20% water solution to carry out the operation.

Four, storage and transportation
1 products are stored in a dry and ventilated place, avoid direct sunlight and rain, away from fire, kept separate from the base class.
2 transport and handling should be light light unloading, packaging to prevent breakage. Transport should be covered.

Five, matters needing attention
1 products belong to the corrosion products.
2 should be separated from the flammable or combustible materials, alkali, metal powder, etc.. Non mixed storage and transportation. When moving to light light unloading, prevent damage to packaging, packaging and handling operation should pay attention to personal protection.
3 in the use of the process, the staff should wear self absorption filter gas mask (full cover) or air respirator, wear rubber acid and alkali resistant clothing, wear rubber gloves. Solid acid is strictly prohibited to contact the skin, once contact, immediately wash with water.
