Abstract

Abstract: The technologies, FRZ and EYL, are comprehensive injection increase ones derived from analyzing production history and present situation of water injection development in waterflood production area, Xinjiang Oil Company Ltd. Throughout,and introducing foreign advanced Technology and the experi-
ence. The effectiveness from Lab test and in-situ application with FRZ+EYL comprehensive infection increase are described,the main reason resulting in reservoir plugging is analyzed,and solution is induced. Through 32 wells/times test in five years in Xishanyao Formation, Cainan Oilfield, a satisfactory
injection increase and plug removal effectiveness is achieved.

Key words: injection increase, plugging, plug removal, stimulation
