Abstract

Through constantly deepening the understanding of the reservoirs and adopting effective measures of adjustment and control, the low permeability heterogeneous reservoirs, Xishanyao reservoirs of Cainan oilfield, have been developed for four years in succession at the rate above 2.5% while maintaining the water-cut increasing rate under 3.5%. It means that the development of the reservoirs of the has reached a high level in Cainan oil field.
