Contrary to this usual behavior, the Bohai Bay Basin of eastern China,34 which evolved as a Cenozoic rift basin, experienced intense tectonic reactivation during the 2004; Gong et al, 2010). However, results from these earlier studies simply recognized the 39 two tectonic events (strong faulting and anomalously high rates of tectonic subsidence) and 40 noted their role in determining the hydrocarbon habitat of the basin.…”

“…Oil and gas exploration in recent years has confirmed that predominant migration pathway and communication with trap is the key to hydrocarbons accumulation. The predominant migration pathway has three characteristics: ① Along the Tan-Lu fault zone there are still very frequent natural earthquakes, distributed in an active region of major fault , and the late-stage fault is still active (Gong et al, 2010). ➁ The central inversion structures and the large boundary fault are predominant migration pathways.…”

The Liaozhong Sag is one of the major oil-bearing areas in offshore Bohai Bay Basin and is obviously characterized by late-stage hydrocarbon accumulation. In this paper our study was focused on strong activities of tectonic movement in the Liaozhong sag. In terms of source rock thermal history analysis, generation, migration and accumulation of hydrocarbon, late-stage hydrocarbon accumulation and enrichment pattern were summarized. Apatite fission track analysis and evolutionary history of the Easy% Ro model simulation of source rock showed that major source rocks became matured rapidly at the time 5.1Ma from the present. Fault analysis, showed that hydrocarbon migration in the study area was mainly the result of fault transportation. Fluid inclusions indicated that the accumulation period of oil and gas reservoirs was 5.1Ma from the present. Our study showed that late-stage rapid hydrocarbon generation, late-stage vertical fault transportation, hydrocarbon accumulation near source rocks and late-stage rapid in-filling are the main features of hydrocarbon accumulation in the Liaozhong Sag. The abnormal high pressure and fluid inclusion homogenization temperature anomaly are indications of late-stage episodic reservoiring and in-filling. Regional reservoir-cap rock combination of Eocene Shahejie Formation and Oligocene Dongying Formation, predominant transport channels and relevant traps formed by the complex tectonic movement of the Tan-Lu Fault are major factors controlling hydrocarbon accumulation. Episodic reservoiring of formation overpressure, near-source accumulation and fault control constitute the oil and gas enrichment pattern of the Liaozhong Sag.
