The physical properties of the reservoirs and the crude oil in the district are very good, and great single reservoir output was obtained in the early stage of production. At present, the district has intered into the medium later stage of production.But the recovery percents of the reservoirs are different because their types are many and complicated. There is still remaining oil in unexploited and exploited reservoirs. Detailed secondary oil recovery technology and measures are proposed after the analysis of geological condition, reservoir characteristics, and the present situations in well drilling, well completion, downhole operation and oil production technology.
