| Abstract: | The reservoirs at Wenmingzhai Oil Fields in Zhongyuan are characterized by higher permeability, severe inhomogeneity and very low pressure and is contaminated in course of water flooding and in various chemical operations. For acidizing the producing wells at Wenminzhai a foaming acid system is developed. The acidizing fluid used is composed of following slugs: preflush foam, pad foaming acid (12-15%HCl, compounded), basic foaming acid(10-12%HCl 2%HF 2%HAc,compounded), overdisplacing fluid, and backflow aid fluid. The field uses of the foaming acid system in 26 acidizing operations (in 22 wells) are described. |
