马都拉海峡盆地属特提斯构造域东段,晚渐新世至早中新世裂后稳定沉降时期沉积大面积碳酸盐岩,是区内最重要的油气储层之一.为探讨该时期盆地演化模式,依据马都拉海峡盆地钻遇库炯组的钻井数据和岩心照片以及约120 km长的二维地震数据,通过井沉积相和地震相分析,将盆地地震相划分为6种类型,识别出库炯组珊瑚生物礁以区内F6反转断裂带为界具有明显的南北分区特征.依据珊瑚生物礁生长发育所需特殊环境,认为马都拉海峡盆地裂后沉降期被一系列EW向正断层分为中南部浅海陆架开阔台地区和北部相对深水区,呈现出"南高北低"的古地理特征.

墨西哥湾盆地东南部位于北美板块与加勒比板块碰撞交汇区域,是墨西哥湾地区构造最为复杂区域。涉及两大板块,北美板块和加勒比板块;两个二级板块,尤卡坦板块和巴哈马-佛罗里达板块。在总结前人研究成果基础上,结合深海钻探计划(DSDP)钻井资料以及最新二维地震数据,通过地震相特征识别,分析研究区构造演化过程,探讨板块之间相对运动对墨西哥湾盆地东南部区域的控制作用。结果表明:(1)墨西哥湾盆地东南部现今包含北古巴前陆盆地以及盆地北部被动大陆边缘的不规则中央裂陷区;(2)该区域经历多期构造活动,早侏罗世至中侏罗世中期南美板块与北美板块之间背向分离,白垩纪加勒比板块逆冲北美板块,晚白垩世早期海平面上升以及尤卡坦台地与佛罗里达台地抬升,白垩纪末期加勒比板块北侧古加勒比弧与北美板块碰撞拼合;(3)在早白垩世晚期,由于北美板块内部尤卡坦板块与巴哈马-佛罗里达板块之间的张裂运动,发育大量张性断层,产生NW-SE走向的地堑、半地堑构造样式。

马都拉海峡盆地北部外陆架台地发育有E-W向一字排列的颗粒灰岩生物礁体。该生物礁是有孔虫(主要为抱球虫目)壳体经过各种沉积作用形成的堆积体,发育于早上新世挤压反转期盆地北部边缘区。由于生物礁生长发育所经历的特殊性,其岩石学特征等信息常常具有标志性的反映,因此礁体的剖面反射特征和地震属性相比于围岩会存在不小的差异。这些差异为人们利用地震解释和地震属性提取技术识别生物礁奠定了基础,如在地震剖面上,生物礁往往出现对称丘状外形反射、礁前斜坡前积反射、礁内部杂乱反射和不连续强反射的特征等等。以O-2井钻遇的存在抱球虫化石的马都拉海峡盆地上新统芒杜组沉积地层为研究对象,从地质背景入手,描述了盆地的新生代构造特征和发育各时期所对应的地层。通过进行层位标定和三维地震解释,结合地震属性提取技术,同时考虑到生物礁的发育形态与环境,最终获得了盆地抱球虫颗粒灰岩生物礁在空间上的分布。最后,本文结合盆地历史上的沉积构造活动,提出反转断裂带活动是研究区控制生物礁生长的重要因素,并据此总结了马都拉海峡盆地芒杜组台地边缘生物礁的发育模式。

Background: Emergence agitation (EA) is a common phenomenon observed in pediatric patients following general anesthesia. This study aimed to assess the efficacy of propofol and fentanyl in preventing EA and to compare their associated complications or side effects. Methods: This prospective randomized observational comparative study was conducted at Dhaka Medical College Hospital from July 2013 to June 2014. The study aimed to evaluate the effects of propofol and fentanyl on EA in children aged 18 to 72 months undergoing circumcision, herniotomy, and polypectomy operations. Ninety children were included in the study, with 45 in each group. Patients with psychological or neurological disorders were excluded. Various parameters including age, sex, weight, American Society of Anesthesiologists (ASA) class, duration of anesthesia, Saturation of Peripheral Oxygen (SPO2), heart rate (HR), respiratory rate (RR), Pediatric Anesthesia Emergence Delirium (PAED) score, duration of post-anesthesia care unit (PACU) stay, incidence of laryngospasm, nausea, vomiting, and rescue drug requirement were compared between the two groups. Results: Age, sex, weight, ASA class, and duration of anesthesia were comparable between the two groups. Perioperative SpO2 and HR were similar in both groups. However, the PAED score was significantly higher in the fentanyl group during all follow-ups except at 30 minutes postoperatively. The mean duration of PACU stay was significantly longer in the fentanyl group. Although the incidence of laryngospasm was higher in the fentanyl group, it was not statistically significant. Conversely, nausea or vomiting was significantly higher in the fentanyl group. The requirement for rescue drugs was significantly higher in the fentanyl group compared to the propofol group. Conclusion: Both propofol and fentanyl were effective in preventing emergence agitation in pediatric patients undergoing various surgical procedures under sevoflurane anesthesia. However, propo

文昌凹陷地处南海北部大陆边缘,是一个典型的断陷型含油气盆地,断裂十分复杂。而断裂构造的精细刻画对于不仅对油气勘探开发有着十分显著的影响,各种构造属性常常被用来描述断裂的几何属性,能够有效的反映断裂的几何学特征。本文以文昌凹陷区块为例,应用各种常规地震属性与最近几年新型的似然度属性相互对比,从各属性的基本原理出发结合相应的断裂图形对比,反映各属性的优劣特征,从而有效的避免各属性的缺点,提高断裂识别的能力,初步确定能有效识别断裂地震属性。然而单个的地震属性也会由于自身的局限性无法有效确认断裂以及地质的不连续特征,因此通过对多个地震属性加以结合,以断裂为地震目标进行有监督的人工神经网络识别能有效的改善单个地震属性的局限性。结果表明:多个地震属性对比结果表明似然度属性较其他地震属性上有较强的识别能力,更易突出断裂以及地质的不连续特征。多种属性通过人工神经网络加以识别后能增强断裂的连续性以及提高微小断裂的识别能力。
