Abstract:

After 8 yearl,high speed and high efficiency exploitation in Block 1/2/4 Sudan,it has entered high water cut development,and there will be more complex problems to be faced,such as the obvious decline of oil field production and more difficulty in stabilizing production.According to this situation,comprehensive research on reservoir geology,dynamic analysis on development performance and fine reservoir numerical simulation is conducted to determine that remaining oil mainly distributes vertically on the top of the reservoir,and horizontally in sparse pattern areas,high positions of local structures and near faults.Comprehensive adjustment strategies and measures,such as well pattern infilling,horizontal well,lifting with electric submersible pump,water plugging,reperforating and sidetrack low effect well etc.are implemented on this basis,and oilfield application acquires preferable effectiveness.A whole set of high efficiency development technology for strong bottom water driving block-shaped reservoirs is formed.

Key words: Sudan, bottom water driving reservoir, remaining oil, high efficiency development, numerical simulation, fine reservoir description
