Abstract
With the development of oil drilling and the increase of the deep ocean drilling,the requirements of drilling additives were also promoted to satisfy the high temperature resistance and salt resistance.2-Acrylamido-2-methylpropane sulphonic acid is an acrylamid derivatives with -SO3H and -CH2=CH2- in its molecular structure.The copolymers of AMPS with other monomers were a new kind of drilling additives with many specific characteristics and have been widely used in oil fields.It is a new kind of high temperature resistance and salt resistance filtrate reducers,and it will be an important development direction in the oil fields.
