Abstract

Abstract: A comprehensive study has been made on the descendent injectivity of injection wells in Rongxingtun oilfield, based on experimental data, in-situ sampling and analyses. The results show that the descendent injectivity could be largely accounted for by poor reservoir quality, poor quality of the injection wa-ter, the incompatibility of the water injected and that in the formation, and the improper intensity of injection. Conclusins made in the work provided valuable reference for the further in-jection measures in this field.

Key words: water injection well, injectivity, reservoir quality, compatibility, injection intensity
