摘要: The effects of guar gum polymer and lime powder addition on the fluid loss rheological properties bentonite dispersions have been investigated. Eleven different formulations prepared according to American Petroleum Institute procedures their characteristics determined using a rotational viscometer. Four models used describe pseudo-plastic behavior dispersions. It has observed that all increase with pH show maximum at value about 11.5. effect also extremely increases
