构造-热演化史是认识盆地形成及其动力学机制的重要窗口,也是烃源岩成熟生烃研究的核心问题。随着能源需求的增长以及陆地油气发现难度的增加,海域逐渐成为中国油气勘探的重要接替区与国家能源战略研究的重要领域。秦南凹陷位于渤海海域西北部,勘探前景良好,但勘探程度低,构造-热演化研究尚属空白。文章选取秦南凹陷3条地震剖面,建立25口人工井,进行了构造沉降史和热史模拟,恢复了秦南凹陷构造-热演化历史。研究结果表明:秦南凹陷新生代以来于孔店组—沙河街组四段沉积时期(65~42 Ma)、沙河街组三段沉积时期(42~38 Ma)以及东营组三段沉积时期(32.8~30.3 Ma)分别经历了3期裂陷拉张,总拉张系数为1.27~2.05;对应这3期拉张作用,秦南凹陷基底热流经历3期升高,在东营组三段沉积末期(30.3 Ma)基底热流达到峰值64.0~89.0 mW/m^(2),之后逐渐降低至今;秦南凹陷构造-热演化过程与断裂活动具有良好的耦合关系。研究获得的拉张系数、基底热流等参数对于了解渤海盆地构造演化的深部动力学机制以及指导研究区油气勘探具有重要意义。

Thermal-history reconstruction of the Baiyun Sag in the deep-water area of the Pearl River Mouth Basin, northern South China Sea

引用

Frontiers of Earth Science 2018年第3期12卷 532-544页

作者： xiaoyin tang Shuchun YANG Shengbiao HU Geothermal and Environmental Research Laboratory Xi'an Jiaotong University Xi'an 710049 China CNOOC Research Institute Beijing 100027 China Institute of Geology and Geophysics Chinese Academy of Sciences Beijing 100029 China

The Baiyun Sag, located in the deep-water area of the northern South China Sea, is the largest and deepest subbasin in the Pearl River Mouth Basin and one of the most important hydrocarbon-accumulation depression areas in China. Thermal history is widely thought to be of great importance in oil and gas potential assessment of a basin as it controls the timing of hydrocarbon generation and expulsion from the source rock. In order to unravel the paleo-heat flow of the Baiyun Sag, we first analyzed tectonic subsidence of 55 pseudo-wells constructed based on newly interpreted seismic profiles, along with three drilled wells. We then carried out thermal modeling using the multi-stage finite stretching method and calibrated the results using collected present-day vitrinite reflectance data and temperature data. Results indicate that the first and second heating of the Baiyun Sag after 49 Ma ceased at 33.9 Ma and 23 Ma. Reconstructed average basal paleo- heat flow values at the end of the rifting periods are -57.7- 86.2 mW/m2 and -66.7-97.3 mW/m2, respectively. Following the last heating period at 23 Ma, the study area has undergone a persistent thermal attenuation phase, and basal heat flow has cooled down to ～64.0-79.2 mW/m2 at present.

Tectono-thermal evolution of the Liwan Sag, deepwater area in the Zhujiang River Mouth Basin, northern South China Sea

The Liwan Sag, with an area of 4 000 km-2, is one of the deepwater sags in the Zhujiang River（Pearl River） Mouth Basin, northern South China Sea. Inspired by the exploration success in oil and gas resources in the deepwater sags worldwide, we conducted the thermal modeling to investigate the tectono-thermal history of the Liwan Sag,which has been widely thought to be important to understand tectonic activities as well as hydrocarbon potential of a basin. Using the multi-stage finite stretching model, the tectonic subsidence history and the thermal history have been obtained for 12 artificial wells, which were constructed on basis of one seismic profile newly acquired in the study area. Two stages of rifting during the time periods of 49–33.9 Ma and 33.9–23 Ma can be recognized from the tectonic subsidence pattern, and there are two phases of heating processes corresponding to the *** reconstructed average basal paleo-heat flow values at the end of the rifting events are -70.5 and -94.2 mW/m^2 respectively. Following the heating periods, the study area has undergone a persistent thermal attenuation phase since 23 Ma and the basal heat flow cooled down to -71.8–82.5 mW/m^2 at present.

Tectonic subsidence of the Zhu I Sub-basin in the Pearl River Mouth Basin, northern South China Sea

The Pearl River Mouth Basin, which is situated on the northern margin of the South China Sea, has attracted great attention not only because of its tectonic setting but also because of its abundant hydrocarbon resources. We have analyzed the Cenozoic tectonic subsidence history of 4 drilled wells and 43 artificial wells from the Zhu 1 Sub-basin of the Pearl River Mouth Basin by back-stripping, using newly interpreted seismic profiles. We also calculated the average tectonic sub- sidence rates of the four sags in the Zhu 1 Sub-basin. The rifting and post-rifting stages are separated by abrupt changes in the tectonic subsidence curves and average subsidence rates. In the eastem sags of the Zhu 1 Sub- basin, tectonic subsidence started to slow at ca. 30 Ma, compared with ca. 23.8 Ma in the western sags. This probably corresponds to the timing of break-up and suggests that tiffing in the Pearl River Mouth Basin ended earlier in the eastern sags than in the western sags. Anomalously accelerated tectonic subsidence occurred at 17.5-16.4 Ma during the post-tiffing stage, with average subsidence rates as high as 301.9 m/Myr. This distin- guishes the Pearl River Mouth Basin from classical Atlantic passive continental marginal basins, which demonstrate exponentially decaying post-rift tectonic subsidence.

Dear Editor,Available evidence regarding the most suitable treatment strategies for hepatocellular carcinoma(HCC)with inferior vena cava tumor thrombus(IVCTT)is extremely limited,and the median overall survival time for these patients after liver resection is only 17.76 months[1].Other local or systemic treatments for HCC with IVCTT result in a median overall survival time ranging from 5.88 to 15.36 months[1–3].Thus,new therapeutic strategies are urgently needed to improve the survival of HCC patients with *** antigen receptor(CAR)T-cell therapy has seen success in treating B-cell neoplasms with impressive outcomes[4].However,this therapy alone has shown limited efficacy on solid tumors,such as HCC[5].

大地电磁测深(MT)由于勘探深度范围较大,且对温度、流体、岩浆房和岩性等与热储相关的地质条件的敏感度较高,因而成为火山区地热勘探和岩石圈结构研究中常用的一种地球物理勘探手段。地壳和上地幔的电性结构与热结构之间存在着密切的联系,通过解读二者的关系,可以刻画更为精细的岩石圈结构模型,进而掌握火山区的构造特征和热演化过程,了解其岩石圈地球动力学机制。本文着重介绍了MT方法的原理以及从野外数据采集到后期数据处理的过程,综述了MT法的应用特点以及电导率与温度之间的关系,通过实例分析,介绍了国际上这一方法在火山区地热勘探和岩石圈热结构研究中的应用进展,展示了MT法在新西兰Taupo火山区Ngatamariki高温地热田0~3km地热资源勘探中的应用;以埃塞俄比亚Afar省的Tendaho地热田和Badi火山为例,分别讨论了0~20km和0~50km不同深度的电性结构特征及其与温度存在的内在联系,探讨了形成火山的驱动机制;以日本九州岛的Shinmoe-dake火山为例,介绍了大地电磁测深和温度监测在火山监测方面的应用。最后简述了国内MT法在火山区的应用进展以及存在的问题,并利用上地幔电导率与温度的关系以及岩石圈内硅酸盐熔体不同含水量引起的电导率随温度的变化关系,初步估算了长白山天池和阿尔山火山区的莫霍面以下的温度以及长白山天池火山区的高温岩浆房温度。
