摘　　要：利用BasinMod-1D软件恢复了北部湾盆地福山凹陷代表井的埋藏史和热史,结合流体包裹体均一温度,确定福山凹陷始新统流沙港组和渐新统涠洲组油藏为一期成藏,成藏时间为中中新世末期至上新世早期。油气主要成藏时间与源岩大量生排烃期和圈闭形成期很好地匹配,有利于该区油气的充注成藏。The reconstruction of burial history and thermal history of the Fushan depression, Beibuwan basin, by the BasinMod-lD program, in combination with the homogenization temperature of fluid inclusions, reveals that the Eocene Liushagang Formation and the Oligocene Weizhuo Formation are reservoirs with only one episode of hydrocarbon charge and are formed during the late Middle Miocene-the early Pliocene. The main charging timing of the reservoirs matches well with the hydrocarbon generation and expulsion periods, which is favorable for hydrocarbon accumulation in the area.
