Polylactic acid applications
Oil extraction (gas) special soluble steering temporary plugging agent---PLA (Poly lactic Acid) Product SpecificationThis 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.
