Tanlu Strike-slip Fault Zone Influence on Hydrocarbon Accumulation in Jiyang Depression

Tanlu fault zone in depression reservoir formation has a important control function, it is Feasible to guide oil and gas exploration through research the correlation of them. The giant strike-slip fault zone in the multi-phase activity is the main driver of oil and gas migration, multi-phase fault is generated from oil and gas in space and time, the main medium of mass migration. From region tectonic background, activity periold, and mechanical properties of three aspects, the basic structure, stratigraphy, hydrocarbon accumulation characteristics of research, obtained the Tanlu fault zone and distribution of oil and gas have relevance: From tectonic background aspect, Jiyang depression along the TanLu fault zone in the feather fracture formed longitudinally, transversely into clusters with, local patches of complicate oil system; From activity period aspect, it is relative oil enrichment in tanlu fault active period of Paleogene and Neogene reservoirs; From mechanical properties aspect, Paleogene dextral strike-slip background stretching, transtensional stress field, Neogene right thrust under the background of the E-W extrusion stress force field could have caused hydrocarbon accumulation.
