摘要
Abstract
Tanlu Fault is the most important strike-slip fault in East Bohai; Cenozoic Tanlu Fault here has experienced three stages: extended faulted rift, fight-rotated strike slip and re-moving of late structure. Early Palaeogene extended rift and Late Palaeogene fight-rotated compresso-shear strike slip in Tanlu Fault provide super oil-genera-ting and much better entrapping conditions in Eastsouth Bohai. And furthermore the above structural movements control the formation of Eocene and Oligocene lacustrine source rocks, thus in the end enormous hydrocarbon traps have generated. Multi-stage movements of these faults directly dominate the distribution of hydrocarbon and its enriched layers. The studies show that the syndepositional fault and strike-slip fault belts of long-term inherited movement nearby the oil generating sags are the favorable plays for hydrocarbon accumulation, and moreover the sub-heave belt and the strike-slip fault belts in the eastern margins of Qingdong and Laizhou Bay Sags are predicted to be favorable petroleum exploration play in this this region.关键词
