General Introduction

JMS-I is polyether organic polymers with different molecular weight and molecular structure. It is the outcome product of polymerization of expoxyethane and expoxypropare monomers under different condition. It belongs non-ionic low molecular block copolymer, so it has features of ordinary copolymers as well as features of non-ionic surfactant. It has the characteristics of small amount of reference, low foaming rate, non-fluorescence, which is good for oil-gas bed, well bore stability, reducing friction, anti-sticking, preventing mud drum. It is a highly effective mud additive.
