“趋势厚度法”在塔里木盆地阿克库勒凸起地层剥蚀量恢复中的应用
|
摘要
恢复地层剥蚀厚度是定量研究构造演化史和油气地质定量分析的重要基础工作。由于受资料程度及区域地质等条件的限制,许多传统方法都具有局限性。这里结合阿克库勒地区海西期构造运动剥蚀量较大,且形成的侵蚀面在地震剖面上极易识别的实际情况,提出了利用趋势厚度恢复剥蚀量的方法。并利用此方法对阿克库勒凸起的志留系和中~上奥陶统被剥蚀的地层进行恢复,其结果对这一地区的构造发展史和油气成藏研究,具有一定的指导意义。
The restoration of denuded cover is of great importance to the study on the tectonic development,evolution and the petroleum-controlling geological conditions.Being restricted by the detailed of data and the regional geological conditions,many methods can not be used.An easy method of denudation recovery "trend thickness",based on the facts that the erosion-thickness is tremendous and the erosion surface formed through the early Hercynian tectonic movements in Akekule lobe are very distinct is put forward in this paper.Recovery of the denudation of Silurian and Middle Upper Ordovician is tried with this method and the results are valuable for guiding the development history of geology and hydrocarbon accumulation in this area.
