Product description

The product is a kind of multi-function additive used in oil/gas well development. It is used both in fracturing liquid and in acidizing fluid. It has good compatibility with the additives used in fracturing liquid and acidizing fluid and plays the role of reducing fracturing liquid rubber breaking residue, acidizing residue surface tension and oil-water interface tension. It also plays an important role in increasing fracturing liquid and acidizing fluid return rate, preventing stratum being polluted and reducing damage to oil layer. The additive has good wettability and thermo-stability. The use of the product is easy.

Instructions for Use:

The additive is used to prepare treatment liquid such as fracturing liquid, compound acidizing fluid and conventional acidizing liquid. Preparation in following sequence:

1. Fracturing liquid

Follow construction methodology and working liquid preparation program. When the prepared base liquid is up to required viscosity, the cleanup additive in the quantity determined in design (usually 0.3%) is added to the base liquid and pumped evenly.

2. Compound acid

When compound acid is prepared at site recipe, add cleanup additive of computed amount, mix it up with the acid.

3. Conventional acid

Add cleanup additive of determined quantity, corrosion inhibitor, iron ion stabilizer, clay stabilizer and mutual solvent into hydrochloric acid, use water to dilute these additives to designed concentration, pump the mixture.

Conduct the works in line with the methodology planned for conventional fracturing, compound acidizing and conventional acidizing.

Packaging and Storage

1. Packaging: The product is usually packed in 200L steel barrel, plastic barrel or as required by the customer.

2. Storage: Store the product in well ventilated and cool warehouse, keep it off sunlight and rain. Warranty: one year.
