The geology of the ocean basins has been investigated by geophysical methods and by sampling deepsea sediments. The theory of seafloor spreading, the geothermal evolution of ocean lithosphere, the subsidence history of ocean floor, the hot-spot theory, the theories on the development of active and passive ocean margins, formulated on the basis of geophysical considerations, have been confirmed by drilling investigations. Studies of samples from beneath deepsea floor provided evidence for climatic cooling...

The geology of the ocean basins has been investigated by geophysical methods and by sampling deepsea sediments. The theory of seafloor spreading, the geothermal evolution of ocean lithosphere, the subsidence history of ocean floor, the hot-spot theory, the theories on the development of active and passive ocean margins, formulated on the basis of geophysical considerations, have been confirmed by drilling investigations. Studies of samples from beneath deepsea floor provided evidence for climatic cooling during the Cenozoic, and yielded data for the recognition of crisis in ocean environments and for the reconstruction of paleoceanographic circulations.

1968年以前,研究洋底地质学的手段主要是地球物理学和海洋地质学.1968年,联合海洋研究所深部取样组织(JOIDES)成立,并在同一年发起开展深海钻探计划(DSDP).从1968年到1983年,格拉玛挑战者号钻井船做了多次环球航行,在96个航次中总共完成了624个钻孔.这些工作使海洋地质学发展成为一门可以与大陆地质学并驾齐驱的学科.现在,我们不仅可以通过深钻或直接研究深海岩芯来验证早先根据地球物理调查提出的各种理论推测,钻探本身还带来了许多意想不到的新发现.这些新数据、新思想和新结论极大地加深了我们对海洋演化历史的认识.本文试图就我们在深海钻探计划实施15年以后获得的主要成果作一总结.

The major source beds in the oil— bearing basins of Xinjiang are Paleozoic formations, therefore, it is rather important to study the paleogeothermal regimes of the basins.For the further study of the geothermal histories of the basins, the method of fission scar tracks in apatite is adopted, which suggests that the annealing temperatures (70~125℃) of fission tracks in apatite are within the temperature range (60~110℃) of substantial oil generation. Besides, the method is also used for solving the thermal history and some basic geological problems of sedimentary basins. The age of fission tracks represents the geological age of uplifting and erosion, s(?) it can be used for the timing of uplifting and erosion. The authors suppose a method of reconstructing geothermal history using enclosure temperature.The geothermal evolution of the Junggar Basin is divided into three major phases: a) the geosynclinal phase (Carboniferous Period) with paleothermal gradients, of 8~5 C/100m, b) the foredeep phase (Permian to the end of Triassic Period) with paleothermal gradients of 5~3℃ 100 m, and c) the platform phase (Jurassic to Paleogene) with paleothermal gradient of 3~2℃ 100 m. The Carboniferous and Permian source beds in a few major depressions of the basin reached the oil generation peak stage during Permian and Triassic Periods,therefore, the authors suggest that emphasis should be placed on finding Cenozoic reservoirs coupled with Paleozoic source beds.

新疆含油气盆地的主要生油层是古生界,研究盆地的古地温显得尤为重要。 为进一步研究盆地的热史,引进了裂变径迹法,即磷灰石裂变径迹退火带上—下限温度为70~125℃。同石油主要形成于60~140℃之间相接近。此方法还可解决沉积盆地热历史及某些基础地质问题。裂变径迹年龄代表抬升剥蚀以后的地质年龄,可推断抬升剥蚀作用发生的时间。提出了用包裹体溫度认识地热过程。 准噶尔盆地地溫演化可分为三个主要阶段:地槽期(石炭纪时期)古地温梯度8~5℃/100m:山前坳陷期(二叠—三叠纪末)古地温梯度5~3℃/100m:地台期(侏罗—早第三纪)古地温梯度3~2℃/100m。盆地中几个主要凹陷内石炭、二叠系生油岩在二叠、三叠纪时就进入了生油高峰期,因之应特别重视寻找古生新储的油气藏。

The restoration of geothermal history is one of important parts in basin modelling. However, in present analysis on geotherms of extensional basins by geophysical techniques, the influence of radioactive heat generation within the lithosphere is neglected in general. In this paper, therefore, a model of heat generation by radioactive elements of the lithosphere is developed and formulae for geothermal history and subsidence history are proposed. A fact is obvious that the geothermal history of extensional basins is much affected by the heat generation of radioactive elements, therefore, it can not be overlooked in the analysis cf the geothermal evolution of extensional basins.

恢复盆地地热史是盆地模拟中的一个重要部分。目前,用地球物理方法恢复拉张盆地的地热史都忽略了岩石圈放射性元素生热的影响。本文中,我们研究了放射性元素的生热效应模式,给出地热史和沉降史计算公式,发现放射性元素的生热效应对地热史影响很大,不能忽略。用这些公式恢复苏北盆地一口井的古热流和古地温,并模拟镜质体反射率(R~0),与实测值吻合较好。同时,用不含生热效应的模式恢复该井的热流,则与实测值相差很大。所以,用地球物理方法恢复大陆内部拉张盆地的地热史不能忽略岩石圈内放射性元素的生热效应,必须用含放射性元素生热率的地热史模式。
