Abstract

The Xindong area is located at the conjunction of several structural belts, among which the Xinzhen structure constitutes the principal structural belt of the research area.The faults of the area display obvious growth and succession, and reached the acme in their development during the deposition of Es₃-Es₂ and Ed.Based on the analysis on balanced cross-section evolution of 4116 survey line, the Cenozoic tectonic evolution of this research area could be divided into three stages :pre-Es₃ embryonic stage, Es₃-Ed shaping stage, and Ng-present decline stage.The oil resource of this area mainly came from the nearby Minfeng and Niuzhuang sags.Ed and Ng-Nm are two oil and gas reservoir forming phases, and the latter is the main one.The generated oil and gas migrated laterally in the vicinity and accumulated in deep trap consisting of Es₄ and Es₁^1-2x-Es₂; then, the oil and gas continued to migrate through large-scale accumulation body and active faults to the research area and concentrated in the Paleogene fault blocks involved in wing and core parts of structures near sags.Long-term development of active faults led to the change in condition for formation of oil and gas, so part of the generated oil and gas migrated upward along the active faults and formed secondary hydrocarbon reservoir in the Neogene beds.
