Abstract

High temperature and high salinity environments in deep well drilling can easily lead to the failure of drilling fluid performance, leading to accidents such as well collapse and leakage, and affecting drilling safety and effici...

A water-based fluid loss additive with temperature resistance up to 220 ℃ was prepared by using acrylamide(AM)，allyl polyethylene ether(APEG-1000)，sodium p-styrenesulfonate(SSS)，and octadecyl dimethyl allyl ammonium chloride(DMAAC-18) as pol...
