首先研究了第三系沉积物来源和前期热力史的统一性,然后在用裂变径迹法对代表性钻井古地温和地温梯度进行研究和测定的基础上,查明不同时期的温度及梯度和决定该区古地温场变化的主要因素,在恢复地层沉积埋藏史的前提下,综合分析了该区的古地温场和热力史。最后,对该区油气勘探方向和古地温研究方法提出了建议。
Firstly, the origin of the sediments in the Tertiary system and the unity of previous thermal history are studied. Based on the study and determination of the gentle geothermal gradient of the representative drilling well by using fission track method, the temperature and gradient in different periods and On the premise of restoring the burial history of the stratum, the paleogeothermal field and thermal history of the area are analyzed synthetically. Finally, some suggestions are put forward for the research directions of oil and gas exploration and paleo-geothermal in the area.
