| 摘 要： | 磷灰石裂变径迹是研究沉积盆地地热史的强有力工具。胜利油区东营凹陷磷灰石裂变径迹分析表明该盆地的古热作用比现今热作用强。盆地形成初期经历的热事件使其具有较高的热流，随后热流缓慢衰减；３号样品径迹长度的混和型分布说明东营组（Ｅｄ）和馆陶组（Ｎｇ）之间的沉积间断曾引起了盆地古地温的降低。东营凹陷磷灰石裂变径迹退火带位置在２０００～３４００ｍ左右，和生油窗是一致的。

| Abstract: | Apatite fission track is a powerful tool to study the thermal history of sedimentary basin. Apatite fission track analysis of Dongying depression in Shengli Oil Field indicates that the thermal action was stronger in past than at present in this depression. The depression had high heat flux at the beginning of its formation, then the heat flux was attenuated. The mired distribution of confined fission track length of sample No. 3 indicates that the interruption of sedimentation between Dongying formation (Ed ) and Guangtao formation (Ng) has caused the reduction Of paleo-geotemperature. The annealing zone of apatite fission track is located between 2000m and 3400m, and is consistant with the oil generation window of this depression. |
