摘要:

断层是裂谷盆地重要的油气运移通道。对渤海油区大量成功与失利探井的深入分析表明,单纯断面的运移能力并不强,大断层只有与烃源岩内的“中转站”砂体配合,才能为上部圈闭提供充足的油源;凹陷内小断层根部无“中转站”,只能形成小油藏;直立的走滑断层下部无“中转站”,其上部无油藏。深入研究断层的运移能力,会大幅提高勘探成功率。

Abstract:

Oil-gas migration is regarded as one of the most difficult problems encountered in researches of petroleum geology in the world and currently a frontier subject as well. Faults are an important pathway for oil-gas migration in rift basins. A thorough analysis of the success or failure of many exploratory wells in the Bohai oil province demonstrated that oil-gas migration is inefficient simply depending on faults, only in concert with sand bodies within source rocks serving as an “oil-gas transfer station”, can large faults provide traps above with an ample source of hydrocarbons. In sags, small faults without “oil-gas transfer station” at root can only form small oil reservoirs, while vertical strike-slip faults without “oil-gas transfer station” at root can not form oil reservoirs in upside. It will greatly improve the success ratio of exploration to make further studies on oil-gas migration capacity of faults.
