Method to Improve Flooding Effectiveness in the North 16 Water Wells

The North 16 Water Wells has the characteristics such as,complicated geologic structure,strong heterogenousity of pay zones.In the waterflood development of the reservoir,some injectors were under injection,some had big injection-production pressure,big flow resistance,and other issues.We have taken the high-pressure injection,injectors,converted,separated water profile controlling,which have been implemented to adjust production injection structure and improved production injection system.After implementing these measurers,the increasing speed of water cut is effectively controlled,and sweep efficiency and volume efficiency is increased,and the development results are improved.
