文章摘要
Cationic polymer fluid loss additive (CPFL)
was prepared by using the reaction of 2,3-epoxypropyltrimethyl
ammonium chloride (EPTMAC) (as cationic
reagent) with the amide group in the molecular structure of
the sodium salt of partially hydrolyzed polyacrylonitrile
fibers (HPAN-Na). The chemical reaction was determined
by studying the infrared absorption peaks of the materials
and the products. The results proved that the cationic
groups of EPTMAC were successfully grafted onto the
HPAN molecular chain. The composition of the molecular
chain of the product CPFL was determined by investigation
and calculation of the elemental analysis results of the
grafted HPAN and the final reaction product CPFL. The
drilling fluid performance was evaluated, and the result
showed that when the cation content was more than
0.27 mmol/g, the drilling fluid would have good resistance
to fluid loss and to pollution from calcium chloride.
