海上油田注水引起的地层损害及增注措施

国外海上油田开发比较早，注水也有较长历史，对产出水回注造成地层损害的主要原因，损害的机理已有较深入的研究，国内海上油田回注产出水的工作起步较完，对产出水造成的地层伤害及补救措施经验不足。随着我国海上油田产能建设和开发规模的不断扩大，急需借鉴国外的先进经验，该文对国外海上油田注水造成的地层损害及增注措施进行了较为系统地调研和分析，其对于国内海上油田注水开发有一定的参考价值。

Formation damage caused by water injection and the corresponding measure of augmented injection in offshore oilfields

Main reasons and mechanism of formation damage caused by produced-water reinjection in foreign offshore oilfields have been studied thoroughly due to the earlier development and longer waterflood history. Little experience on the formation damage caused by the produced-water reinjection in domestic offshore oilfields was accumulated. It is badly in need of using the experience of other countries for reference along with continuous production increasing in our offshore oilfields. The formation damage and the corresponding measure of augmented injection in the foreign offshore oilfields are investigated, studied and analyzed systematically and the result is of some reference value to waterflood development in the domestic offshore oilfields.
