During the“11th Five-Year”, the Jiyang depression has integrally entered into the concealment reservoir exploration stage.Under the conditions of more complex and more concealed exploration targets, and facing more and more difficult exploration situation,the Jiyang depression always maintained a good exploration development situation，and consolidated the resource base for the development of Shengli oilfield. It has important referential significance for further exploration of Shengli oilfield by summarizing exploration features and exploration experience of Jiyang depression in the“11th Five-Year”period. Therefore, through the summary of the distributing characteristics of well types, drilling purposes strata, drilled depth, reservoir types and types of traps that drilled by wells in Jiyang depression in the“11th Five-Year”period，the results showed that the breakthrough from prexploration and risk exploration is important to realize the sustainable development; the upper section of Es4 and the strata above it are still the main exploration target strata system, the Ek and the lower Es4 deep layer have become the reserves focus; the conglomerate reservoir in steep slope, turbidite sand reservoir in the sag slope, beach bar sandstones of gentle slope and the Neogene fluvial sand body such as a lithologic reservoir have upgraded to be the major exploration targets, moreover, the proportion of deep buried hill reservoir also increased significantly as exploration targets. The detailed exploration is the key for a high matured area to obtain progress, and new crucial district to obtain breakthrough. The evaluation of the reservoir and transporting conditions are the main exploration risks for Jiyang depression at present and in the future.
