地层学的发展推动油气地质理论研究的进步

自上个世纪50年代以来,地层学经历了彻底的变革,逐渐由“相模式”、“沉积体系”、“地震地层学”发展到目前的“层序地层学”,形成高分辨率层序地层学和事件地层学的理论体系和研究方法。文章围绕层序地层学、高分辨率层序地层学基本方法及理论体系,与含油气系统相关关系进行了讨论。

On the estimation of mooring line characteristic resistance for reliability analysis

The main aim of this work is to derive a correct formulation for the characteristic resistance of a mooring line segment with lognormally distributed component resistances and substitute an equation proposed by Vazquez-Hernandez et al. [Vazquez-Hernandez AO, Ellwanger GB, Sagrilo LVS. Reliability-based comparative study for mooring lines design criteria. Appl Ocean Res 2006; 28(6):398–406] in a paper published in this journal, which is not correct. The mooring line is considered as a series system and the resistances of individual components of a line segment are statistically independent and identically distributed; furthermore, the case of normally distributed component resistances is also discussed. A comparison with the corresponding equation proposed by DNV-OS-E301 is given. Results show that the formula proposed by Vazquez-Hernandez et al. [Vazquez-Hernandez AO, Ellwanger GB, Sagrilo LVS. Reliability-based comparative study for mooring lines design criteria. Appl Ocean Res 2006; 28(6):398–406] overestimates quite significantly the characteristic resistance of a mooring line segment.     

Limitations of the Korean conventional fisheries management regime and expanding Korean TAC system toward output control systems

In this paper, we focus on the status and trends of the current Korean fisheries management regime. Specifically, this paper briefly introduces the Korean conventional fisheries management regime (KCFMR) and discusses its problems and limitations. In describing policy evolution, this paper finds reasons why the Korean government has chosen a TAC system, an output control approach, besides input control approaches in force for almost a century. This paper also describes the evolution of the Korean TAC system, which is carrying out a pivotal role in Korean fisheries development, and analyzes problems of the Korean TAC system. Finally, this paper gives a perspective on expanding the Korean TAC system toward Output Control Systems (OCSs) such as Individual Quotas (IQs), Individual Vessel Quotas (IVQs), Individual Transferable Traps (ITTs), Community Quotas (CQs), and Individual Transferable Quotas (ITQs).     

油田水动力系统与油气藏的形成

油田水中存在“沉积承压水”和“地表渗入水”两个相对独立而又相互作用的水动力系统,前者由上覆地层重量所引起的地静压力以及地静压力等引起的异常孔隙流体压力所形成,具有内循环承压式水交替特征,后者为大气降水和地表水向储集层的渗入而形成,以外循环渗入或水交替为特征。这两大系统（尤其是前者）的作用在很大程度上控制了含油气盆地中油气的运移、聚集和保存,油气聚集区主要位于水文地质带中的交管阻滞一停滞带内,沉积交替强度的低值区是油气富集区,沉积水的离心流使凹陷中的油气围绕凹陷中心呈带状分布。     

雷州半岛灯楼角海岸地貌演变

灯楼角岬角位于雷州半岛的西南端,地处热带北缘.过去几次开展的区域地貌和第四纪地质调查及制图,均包括本区1),2),[1～2].宋朝景曾做过涉及本区海底的地貌与浅地层调查3),又指导学生研究本段海岸地貌4).近年赵焕庭等[3]开展该区珊瑚礁研究,使用了1960年版航空照片和1964年版1:10000地形图,结合野外调查,进一步研究了本区海岸地貌的演变.     

四川椎实螺属一新种(肺螺亚纲:基眼目,椎实螺科)

作者1987年于四川省乐山市大渡河尾段发现椎实螺属一新种,现命名为乐山椎实螺(Lymnaea leshanensis sp.nov.)。该种与日本琵琶湖产的 Lymnaea onychia 相似,但贝壳的形态、齿式、齿形、两性生殖系统的诸器官、外套膜的色带、个体大小、生活环境和动物区系均有所不同。前者属东洋区系,后者属古北区系。
