Investigation of synthesized polymer on the rheological and filtration performance of water-based drilling fluid system

Emulsion stability was characterized by the T2 value and T2 distribution curve firstly. Based on the molecular structure requirement of the synthesized polymer resistant to high temperature and the lower cost demand of water-based drilling fluid system, the synthesized Poly(SSS/AM/AMPS) was used to improve the rheological and filtration performance of water-based drilling fluid system.295
