背斜

Outcrop oil accumulation is a special accumulation which is located in the wing of an outcrop anticline or in a monocline in the edge of a basin and is controlled by water table .

露头油藏是一种形成于露头背斜翼部或盆地边缘单斜上依靠潜水面控制的特殊油藏，是今后石油勘探的一个新领域。

Anticlines and synclines are the basic deformation forms of sedimentary basins,as well as neutral plane s are the important interface of strata deformation.

背斜、向斜褶皱构造是沉积盆地的基本形变，中和面也是地层变形中的重要界面，在传统的石油地质理论中，一直忽视了这一重要界面。

Anticlines and synclines are the basic deformation forms of sedimentary basins, as well as neutral planes are the important interface of strata deformation. But the neutral plane is paid no attention in the traditional petroleum geological theory.

背斜、向斜褶皱构造是沉积盆地的基本形变，中和面也是地层变形中的重要界面，在传统的石油地质理论中，一直忽视了这一重要界面。

The intervals under the neutral plane at the axial part tensile and also favorablc for oil and gas accumulation, which are the same as those above the neutral plane at the anticline.

向斜轴部中和面以下层段与背斜轴部中和面以上层段一样，都是张性区域，也是油气的有利聚集区。

The results show that structure curvature is negatively related to coalbed gas content,relative gas emission rate,outburst gas and coal amounts which reflect No15 coalbed of Ji is above the neutral plane of folds.That is,the No15 coalbed of Ji Group is compressed in incline and is tensed in anticline,and the higher structure curvature is,the higher stress is.

结果表明，构造曲率与瓦斯含量、瓦斯相对涌出量、突出瓦斯量、突出煤量呈负相关关系，反映研究区己15煤层位于褶皱中和面以上，即煤层在向斜轴部受挤压而背斜轴部受拉张，正曲率值反映煤层受到拉张应力作用，负曲率值反映煤层受到挤压应力作用，曲率绝对值越大，受力越大。

Focusing on them, author has been investigating in open country and collecting, arraging and analyzing material for one and a half year. After having done the study on the new deep prediction, author presents new opinion on the base of part of precious geological opinion .1, Xiaohe deposit direction and turn are mainly controlled by the second structure rochet vault in the back of Bigsnown mountain. It is conjectured that the axis extent with the current direction to the 180# exploring line and turn to northwest-southeast direction. During the extension, the deposit body would extend from deep to low instead from low to deep. The turning place was level corresponding to the core of rocket vault.2, There are a chain of radiate blind regmagenesis controlled by the rocket vault.

笔者针对这两个问题，通过一年半的野外实地调查和室内资料收集整理分析，在进行了新的深部找矿研究工作之后，在认同前人部分地质观点(即小河～石门坎矿带的连续是存在的)的基础之上，又提出了新的观点，即： 1、小河矿床矿体的走向及转向位置主要受大雪山背斜的次级构造火箭山穹隆控制，推测其轴线将沿现在的走向，延伸至180#勘探线附近发生转向，轴线方向逐渐转为北西——南东方向，同时矿体从由浅至深逐渐变为由深至浅的延伸状态。

On the basis of analyzing the forming conditions, establishing reservoir forming pattern of vertical migration-fault sealing, developing petroleum reservoir types of fault sealing and fault together with anticline, it is pointed out that the traps near the deep depression and non-piercement salt dome should be the first choice of exploration target area.

在对该区油气成藏条件分析基础上，建立了研究区盐上层系垂向运移－断层封堵型成藏模式，形成断层遮挡型及断层与背斜组合型两种油藏类型，并指出距离盐上深洼陷较近的、盐丘非刺穿构造上的圈闭是首选的勘探目标区。

Through the analysis of southern, middle and northern sections in combination with the stereographic projection, the authors identified geometric features of the anticline.

中文摘要：阿其克背斜是塔里木盆地西南坳陷南缘的一个横向转换构造，该构造的特殊性在于其枢纽走向与造山带总体是垂直的，而非平行。

The formation of Luye fans cause eastward shift of Beinan Rive. The strath surface developed by lateral erosion was subsequently incised and distributed along the eastern side of the Hua-Dong valley.

这些河阶地受南北延伸的四条主要活动构造线影响而发生变形，自西而东分别是鹿野逆断层、背斜、向斜和利吉断层。

Results Gas accumulation dynamics researches focus on anticlinal trap （including updip structure and stratigraphic trap）, synclinal trap and coalbed gas trap.

结果对天然气成藏动力学机制的研究主要围绕背斜圈闭气藏（含上倾型构造及地层圈闭）、向斜圈闭气藏及煤层气藏3类气藏进行，但是，研究的侧重点差别很大。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
