Esun acid fracturing fluid additive be used as a self generated acid fracturing fluid additives, this product is blended with other agents as acid fracturing fluid,after the acid fracturing fluid injection into oil well, in a certain temperature conditions, lactic acid ester dissolve into carboxylic acid and water, carboxylic acid react with underground rock, which can open a lot of holes channels.During the process of fracturing,it can further improve the reservoir permeability and enlarge the drainage area. Eventually, ethyl lactate degrade into carbon dioxide and water. in a certain temperature and humidity, safe environmental protection.
Esun temporary plugging agent
is made from special polymer and varied natural material,through a special process to develop into series of oil(gas) exploitation specialized product. This product with other processing agent together is injected into the well under, 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.
