Two kinds of cation polymer anti-swelling agents/ sand
controllers were prepared , and their anti-swelling and sand
controlling performance were studied compared with common anti-
swelling agents/ sand controllers applied in oil field , the results
suggested that the production possessed relatively good anti-
swelling and sand controlling performance. At the same time ,the
effect on its performance of sand partiial-size and flooding
medium viscousity were studied also ,the results suggested that ,
when sand partical-size was bigger than 013mm ,flooding medium
viscousity was higher than 50mPa·s ,the production prepared in
this article nearly losed its sand controlling performance.
