Embodiment Construction
[0006] (1) Preparation of anti-high temperature and anti-salt anti-shearing agent for drilling fluid:
[0007] The preparation method of the anti-high temperature and anti-salt anti-shearing agent for drilling fluid in this embodiment comprises the following steps:
[0008] (1) Raw material preparation: alkali metal, water, starch, organic sodium salt and reduction initiator, calculated with the addition amount of every 100 milliliters of water: alkali metal 18.8 grams, starch 24.7 grams, organic sodium salt 13.3 grams, reduction initiator 0.15 gram;
[0009] (2) Mother liquor preparation: according to the raw material ratio of step (1), alkali metal and water are reacted, and starch is added after completion of the reaction;
[0010] (3) Chelate copolymerization: add organic sodium salt to the mixture obtained in step (2) under stirring, then heat to 80°C, and react for 1h;
[0011] (4) Adding auxiliary materials: adding a reduction initiator to the mixture obtained in step...
