There are low permeability and poor crude oil physical property in the second-class oil layer of the eastern transitional zone, especially crude oil viscosity is high, and underground crude oil viscosity reaches 14mPa.s. After the weak-alkali ASP combination flooding was carried out, the liquid production dropped sharply in some oil production wells, during the initial effective stage of the oil production wells, by combining the analysis of fine geological research results and the dynamic and static reflection of oil production wells, fracturing transformation was implemented for oil production wells, and good oil increase and water decrease effect was achieved.
