厄瓜多尔奥连特盆地Main-M1砂岩储集层是该盆地近年来重要的构造-岩性圈闭勘探目的层系,寻找砂体和岩性尖灭带是Main-M1砂岩勘探的关键。该盆地为晚白垩世弧后热沉降盆地和新生代前陆盆地的叠合盆地,在构造上分为西部逆冲褶皱带、中部前渊带和东部斜坡带,在前渊带发育一系列近N-S走向长轴背斜。综合观察和分析发现,在研究区内长轴背斜上生长了1个碳酸盐岩建隆,地震上具有明显的边界反射形成丘状外观和较连续的弱振幅内部反射,测井上具有厚层、近箱型低GR响应特征。该建隆表明在其沉积的坎潘阶时期,长轴背斜已经开始抬升,将背斜顶部推升至古水面附近,形成建隆局部生长的条件。压实回剥方法恢复古地貌证实,长轴背斜在坎潘阶早期开始发育,构造抬升幅度为7~10 m。由于构造抬升和建隆发育始于Main-M1沉积前,抬升古地貌可影响砂岩沉积。根据背斜上数十口已钻井Main-M1砂体厚度统计,发现背斜顶部砂岩储集层整体较发育,但古建隆顶部砂层厚度减薄或者缺失,在背斜的南部延伸段,构造顶部砂岩缺失,仅在东部侧翼富集。提出了近N-S向背斜古地貌影响Main-M1砂体沉积,使砂岩于富集于构造下倾方向的控砂模式。该模式可形成上倾尖灭型构造-岩性圈闭,从而提供了通过古地貌恢复在奥连特盆地前渊带寻找新圈闭的勘探思路。

深水非造礁石珊瑚(Ahermatypic coral)中的扇形珊瑚属(Flabellum)在东海大陆架海区不仅数量多,而且是优势种。因扇形珊瑚属自第三纪的始新世至今都有生长,所以不但引起现代底栖生物学者的关注,而且也是第三、第四纪古生物工作者常常提及的种属。自Lesson 183.年建立Flabellum以来,不断有新种报导,但也有不少学者对这些新种提出异议,认为是同物异名,时时在合并。有分有合,意见纷纭。因此,这一属的种类庞杂,相当混乱。我们这次调查中发现的红色扇形珊瑚(Flabellum rubrum)和***-

【研究目的】潮汕坳陷构造隆起部位受砂岩储层发育程度和构造条件的双重控制,其侧翼洼陷为其提供烃源,是油气聚集最有利区。利用地震反演的弹性参数进行含油气性预测的潮汕坳陷中生界砂岩储层具有明显的低密度特征,而其他岩性的密度偏高。【研究方法】利用叠前地震全道集资料直接反演密度、泊松比等弹性参数,通过密度反演成果预测砂岩储层发育情况和烃类分布,实现对中生界含油气性的预测。【研究结果】泊松比对烃类比较敏感,储层含烃后具有明显的低泊松比特征。【结论】利用地震反演的弹性参数进行含油气性预测表明,烃类异常特征明显,预测构造隆起部位具有较好的含油气性。叠前弹性参数反演技术使无井区域储层预测的多解性与不确定性大大降低,提高了反演结果的准确性和可靠性,这项技术的应用对于类似研究新区的储层预测和烃类检测工作,具有很好的应用推广价值。

The rapidly changing Antarctic sea ice has garnered significant interest. To enhance the prediction skill for sea ice and respond to the sea Ice Prediction Network-{3.'s latest call, this study presents the reforecast results of Antarctic sea-ice area and extent from December to June of the coming year with a Convolutional Long Short-Term Memory(Conv LSTM)Network. The reforecast experiments demonstrate that Conv LSTM captures the interannual and interseasonal variability of Antarctic sea ice successfully, and performs better than the European Centre for Medium-Range Weather Forecasts. Based on this, we present the prediction from December 2.2. to June 2.2., indicating that the Antarctic sea ice will remain at lows, but may not create a new record low. This research highlights the promising application of deep learning in Antarctic sea-ice prediction.

目前,填海工程动态监测主要采用陆域RTK测量与水下侧扫测量相结合的监测手段。文中在填海工程动态监测过程中开创性地使用无人机低空遥感监测手段,通过获取填海过程中高分辨率遥感影像,结合实测填海坡脚线数据,能更直观地展示填海过程中的界址与面积变化情况。同时也可以对已形成陆域部分进行动态监测,可以作为填海工程动态监测的有效补充手段。今后,随着机载激光测深技术的发展,将激光测深设备搭载到无人机平台上,可以对填海工程进行海陆一体化监测。

Recent studies on the role of carotenoids in aquaculture have investigated their function in regulating pigmentation, growth, survival, and immune activity of aquatic animals. These carotenoids include astaxanthin, canthaxanthin, lutein, zeaxanthin, and tunaxanthin. Astaxanthin and canthaxanthin are the main synthetic carotenoids used world-wide in the aquaculture industry. They play an important role in protecting cells and organisms against photosensitized oxidations. Direct evidence of carotenoids functioning as antioxidants in vivo has been reported in animal models. In addition to their established biological effects as antioxidants, carotenoids appear to have a great variety of cellular actions that make them remarkable physiological modulators. Consequently, recent attention has been focused on improving our understanding of carotenoids on the physiology and metabolism in aquatic animals with a view to enhance the efficacy of astaxanthin as a carotenoid pigment. This review aims to summarize the function and re{2.rch progress of carotenoids in aquaculture. We discuss the methods used to study the absorption, transport, metabolic transformation and deposition of carotenoids, and their spatial and temporal expression.
