背斜

The stress properties of the upper horizon are different from the lower horizon in anticlines and synelines, which exerting effect on reservoir physical properties. Besides it is related to oil and gas accumulation.

中和面的上、下层位在背斜、向斜构造中应力性质不同，影响着储层的物性，也与油气的聚散有关。

Anticlines are arch-shaped folds in which rock layers are upwardly convex.

典型地背斜是岩层向上凸起的褶曲。

But the author was strangely silent on such details-indeed, silent on everything but anticlines, synclines, axial faults, and the like.

但作者却非常奇怪，对此类细节缄口不言，只谈论些背斜、向斜、地轴偏差类似的东西。

Neotectonic movement in the Jiyang depression mainly formed faults and anticlines, especially, the large revived faults and its fractures. These structures play an important role in the processes of oil and gas accumulation.

摘 要：济阳坳陷新构造运动的构造形迹主要表现为断裂和背斜构造，特别是复活性大断裂及其裂缝，在济阳坳陷油气成藏过程中起着关键性作用。

The distribution of structure fracture is very different, near the hinge of structure and fault, fracture is well developed. On the map, on the structure highpoint of Changchunling anticline and Chaoyanggou terrace fracture is well developed, and strike of fracture is NNW.

平面上，在长春岭背斜构造高部位和朝阳沟阶地构造高部位裂缝较为发育，裂缝发育主要呈北北东向条带状分布，在构造低部位，裂缝发育主要以近东西向和北西向为主。

As to the deeper level structures of Kuche rejuvenated foreland thrust belt, fault-bend folds typified the Northern Linear Anticlinal Zone (Yiqikelike segment, east part of Kelasu segment and Tubei segment) and Qiulitage Thrust Front.

深层构造在北部线性背斜带的依奇克里克段、克拉苏段的东段以及吐北段主要为断层转折褶皱，而在克拉苏段的中西段则主要为被动顶板双重逆冲构造。

Up to date the reserves discovered at shallow targ ets has exceeded 70% of total in Bohai Sea.Neotectonismis chara cterized by:(1)different Q and N center of subsidence,and angular unconformity b etween Q and N;(2)basalt effusion and magma activities frequently;(3)regular dis tribution of earthquake center;(4)intensive later faults (15-2Ma)forming multit ude anticiline in Nm-Ng formations.

目前浅层的油气储量占总储量的70%以上，这是由于海域新构造运动控制了晚期成藏，表现为：第四纪沉降中心与Nm晚期沉降中心不吻合，使得Q与N之间地层呈角度不整合；玄武岩喷发及岩浆活动频繁；沿渤南及郯庐断裂带天然地震震中有规律分布，晚期(15～2Ma)断裂极其发育，在Nm—Ng组地层内形成众多的背斜圈闭。

In the view of sedimentology, the conditions favorable to form rollovering anticlines are interbedding of sandstones and mudstones without too large sedimentary rate.

从沉积学角度看，形成滚动背斜应以不太大的沉积速率为宜，但不能给出绝对值，因为必须考虑下盘与上盘沉积速率的比值，岩性则以砂泥岩互层最为有利。

In respect of exploration practices and based on the studies of evolution mechanisms of the structural deformation in eastern Sichuan, the author, for the first time, clearly states that the best prospects for primary gas reservoirs in eastern Sichuan are the plunged ends of the high and steep anticlines and their neighboring synclines.

在勘探实践上，根据川东高陡构造变形演化机理的研究，首次明确提出了川东高陡背斜倾伏端及相邻向斜区是今后川东寻找&原生气藏&的最佳勘探领域。

Based on analysis for paleostructural characteristics of above four areas,the paper proposed that there developed a series of paleostructure belts under the background of regional uplifting in latest Mesozoic at the front of south Qilian Mt,and those paleostructures are characterized by NWNNWstriked anticlines and synclines,whose wavelengths are 15～20 km and middlescaled. At the same time,the paper also points out that most areas in western China are lack of upper Cretaceous,which implies the existence of a broad Late Cretaceous plateau in central Asia.

通过这4个地区古构造特征的研究，提出南祁连山前区中生代晚期在区域性隆升的背景下，形成了一系列古构造带，古构造活动的特点是形成北西-北北西走向的背斜和向斜构造，这些褶皱的波长为15～20 km，为中尺度规模。

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。
