PLA in oil exploration

Oil extraction (gas) special soluble steering temporary plugging agent---PLA (Poly lactic Acid)

 Product Specification

This Oil (gas) dedicated to soluble temporary plugging agent is made from special polymer (PLA) and varied natural material, through a special process to develop into series of oil (gas) exploitation specialized product. This product mixed with other processing agent together is injected into the oil well, under the conditions of certain temperature, when acidate or acid fracturing, it temporarily plugs high permeability area to ensure objective layer is equidistribution of acid; after 4-6 hours, it gradually degrade into a carboxylic acid, carboxylic acid get reaction with calcium, magnesium ion under well, further improve reservoir permeability and expand discharge oil area, in order to improve the oil recovery rate, eventually the product degrade into carbon dioxide and water at a certain temperature and humidity, safety and environmental protection. At present, the product is widely used in oil (gas) exploitation in China, Middle East, Europe, America.

 Product Specification

Product advantage

This product (PLA) is a special polymer, biodegradable, non-toxic, no pollution, no residue; good compatibility with other additives.

Recommendation  dosage

This product (PLA) is recommended dosage of 1-3%. can be added directly in acid with uniform mixing, but also can be segment injection with water.
