The Penglai 19-3 and Penglai 25-6 fields are the most typical examples among the fields found in the Tan-Lu fault zone. The structures related to the two fields are fault restraining bends produced by dextral strike-slip movement on faults within the Tan-Lu fault zone. The structures initiated at the late depositional stage of the third member of the Eocene Shahejie Formation (ca. 40 Ma) after the deposition of the main source rocks of the basin. They then experienced a main development stage during deposition of the second and first members of the Eocene Shahejie Formation and the Oligocene Dongying Formation (40–25 Ma). During the Neogene, the structures continued to be enhanced slightly because of continued strike-slip until the early to middle Pleistocene. These structures were characterized by the absence of the preponderance of the reverse separations on faults and might represent the restraining bends in a divergent wrench deformation zone. This study shows that restraining bend structures along intrabasinal strike-slip systems formed after the deposition of the source rocks are very favorable for hydrocarbon accumulation.
