| Abstract: | In this paper the core plugging capability of selective water plugging agent CY 98, a ploymer/resin and water glass mixed gelling fluid, is presented and discussed and its field uses for water plugging in two high water cut production wells at a high temperature and high salinity reservoir of Pucheng, Zhongyuan, are briefly introduced. It is shown that CY 98 is a highly effective water plugging composition(water plugging rates in cores >99%) and is selective in some extent (oil plugging rates 14.7% and 67.7% in two sets of core experiments). The blockages formed in the core are resistant to water flush. The working life of the CY 98 gel blockages displaced into the reservoir zones is long. |
