越南近海的一些前新生代石油勘探局

越南近海前新生代地层在经历了多个演化阶段后,成为固结的大陆架基底。其后,它遭受沉降,并被较年青的沉积盆地所覆盖。在前新生代基底高中已发现一系列油田,如：白虎、曙光、红宝石、龙和其它构造等。广泛分布在沿岸和近海地区的断裂的古生代碳酸盐岩层系是很好的储层,特别在它们已被埋藏在中生代和新生代沉积之下时。一些属于中生代的断裂的碎屑岩系也是较好的储层。然而,中生代深成－火山岩断裂基底高是最重要的储层,并已成     

水深对超浅吃水拖轮系柱拖力的影响

超浅吃水拖轮在浅海对钻井平台进行拖带和井位定位时,必须了解超浅吃水拖轮浅水系柱拖力特性,才能充分利用海潮条件和自身能力完成钻井平台的拖带和定位任务。     

基于构造演化分析的古近系储层预测:以辽西凸起中段沙河街组为例

辽西凸起中段古近系沙河街组缺乏规模性圈闭,储层横向变化快、预测难度大,滚动勘探一直难有较大突破.针对构造、储层问题,采用基于构造演化分析的古近系储层预测方法,综合运用裂变径迹构造反演和空间平衡剖面技术,开展构造演化精细分析,改变传统地层沉积模式,提出辽西凸起高部位发育沙河街组地层的新认识,指导构造解释调整,新增沙河街组...     

AD-2型极谱仪

目前我国生产的极谱仪，虽然类型不少，但是应用性比较专一，按照一般教学和科研工作的实际需要，希望极谱仪能有较多的用途。例如，高等学校仪器分析实验课程中，需要进行经典极谱、单扫(示波)极谱、催化极谱和溶出伏安法实验；在物理化学实验课程中，

Parabolic Wave Propagation Modelling in Orthogonal Coordinate Systems

This paper presents a numerical model study of the propagation of water waves using the parabolic approximation of the mild-slope equation in the orthogonal coordinate system. Two types of coordinate systems are studied: (a) a general form of orthogonal coordinate system and (b) the conformal system, a special form of orthogonal coordinate system. Two typical examples, namely, expanded breakwaters and a circular channel, are studied to validate the model. First, the examples are studied by use of the general orthogonal coordinates. Then the same examples are computed by use of the confonnal system. The computational results show that the confonnal coordinate system generally gives better predictions than the general orthogonal system. A numerical technique for generating the conformal grid is combined with the numerical model to improve the practicability of the model. The comparison between the result from the numerical grid system and that from the analytical grid system shows that reliable computational results can be obtained by use of the numerical confonnal grid system.
