AN APPLICATION OF THE INTEGRATED PROJECT IN WELL STIMULATION AND PROFILE CONTROL IN TIGHT RESERVOIR

The problems faced to development engineering are how to improve the effect of well stimulation and profile control in low permeability reservoir and high permeability sandstone payzone in Huabei oilfield.By using the technology of deepen acid treatment,temporary plugging and hack wash of residual acid in integrated project,the problems mentioned above have been solved successfully and the good effect have been obtained.This article introduced the technology principle,case of history and effect analysis,comparing of results to other wells treated with other technology,the advantage have been shown.
