Description
During the construction process of injection, operation, drilling, fracturing and acidizing, it will inevitably produce clay swelling and migration, which reduce the formation permeability, increase the technical difficult of water injection and production. According to the domestic and international data, we use the new methods to develop a new anti-swelling agent. It can emulsify fresh water or sea water with oil, depress the solid expansion of drill chips, control HTHP FL, produces thin and tenacious mud cakes, helps maintain low shearing rate under HTHP, cleans and stabilizes well holes that a great deal of collapsing shale.
APPLICATION METHOD
In the working solution by adding 2 ~ 4% clay stabilizer.
