增压型走滑转换带对大型圈闭的控制作用
Control of contractional strike-slip transfer zone on large traps:a case study of Penglai 19-3 Oilfield
摘要
Abstract
The Penglai 19-3 ultra large integrated oilfield is one of the typical representatives of oil and gas accu-mulation of the Bohai oilfields in the Tan-Lu Fault Zone.At present,tertiary petroleum geological reserves of the oilfield have reached one billion tons,but there is no targeted report on the formation mechanism of its large-scale traps.To clarify the formation mechanism of traps in Penglai 19-3 Oilfield,geological data were analyzed based on 3D seismic,drilling,structural forward simulation,sandbox physics simulation,and so on.It was believed that the contractional strike slip transfer zone controlled the formation of large traps in Penglai 19-3 Oilfield,and the controlling effect was further explored.The Penglai 19-3 Structure is a large-scale antiform structure controlled by multiple levels and types of transfer zones,characterized by"intermittent contractional uplifting"and"structural finalization during hydrocarbon expulsion".The large traps formed have a good spatiotemporal configuration rela-tionship with late hydrocarbon expulsion from cap rocks and source rocks.The study of the transition zone has certain reference significance for finding large and medium-sized oil and gas fields in the strike-slip fault zone in the future.关键词
