New ideas and methods in the paper:1 The formulas on perforated casing collapse strength were deducted, which offereda convenient method to analyze the relationship between casing collapse strength and perforation;2 The stress and displacement formulas on the system of casing, cement anddeformation under the non-uniform load were deducted, which offered the theoretical found for designing optimally casing string;3 The relationship between structure in-situ field of whole oil field and casing failurewere studied, which offered the scheme for the prediction of casing failure. The process of study in the paper:1 For simulating the relationship between the structure in-situ field and the casingfailure in the oil-deformation, the tests of the uniaxial tensile, compress, tnaxial compress and dilatability were made on the samples of the drill cores from deformation of casing failure position in Yuejing II oil field.

本文的主要创新： 1推导出了射孔套管抗挤强度的解析式，为分析射孔与套管强度的变化关系提供了简便的方法； 2推导出了非均匀地层载荷作用下套管、水泥环和地层组合体的应力和位移解析式，并非均匀作用下套管柱优化设计提供了理论依据； 3研究整个油田区块构造应力场与套管损坏关系，为预测套管损坏提供了可行方案；本文的研究过程如下： 1为模拟构造应力场与油层段套管损坏关系，做了大量的岩石单轴抗拉、单轴抗压、三轴试验以及岩石遇水膨胀试验，获得了研究区块岩石的弹性模量、泊松比、内聚力、内摩擦角以及岩石的线膨胀系数，这此数据为本文研究油层段套管损坏机理研究的理论分析和有限元法提供了实验数据。

Consistent with the rift of the Eurasian plate and the northwestward spread of the Pacific plate, the stress field from large scale of mantle convection displays a skeleton of dumbbell shaped with sinistral compresso-shear at the north, dextral compresso-shear at the south and slip in the middle. Energy converge strong at the south is attributed to the northward movement of the Indian ocean.

Jostling with unemployed labourers of the lowest class, ballast-heavers, coal-whippers, brazen women, ragged children, and the raff and refuse of the river, he makes his way with difficulty along, assailed by offensive sights and smells from the narrow alleys which branch off on the right and left, and deafened by the clash of ponderous waggons that bear great piles of merchandise from the stacks of warehouses that rise from every corner.

到处都是最低级的失业人员、搬运压舱货的脚夫、煤船装卸工、浪荡女子、衣衫褴楼的儿童，还有河滨的渣滓废物，你在中间挤来挤去，吃力地往前走。无数的小巷左右岔开去，巷子里不断涌出令人恶心的景象和气味。笨重的马车装载着堆积如山的货物，从遍布每一个角落的堆栈、库房里哐啷哐啷地开出来，叫人什么也听不见。

Curwood's Dave Engen, market manager for cheese, describes the Curpolene 7202 film as a 2.6-mil, two-ply, coextruded lamination of oriented polyethylene terephthalate, laminated to a proprietary ethylene vinyl alcohol/nylon coex that offers superior resistance to heat and abuse, as well as superior machinability, and barriers and esthetics for nonrespiring sliced cheeses like Provolone and Cheddar.

The disturbing rields caused by the speedup and quietude of upper crustal movement in Tibetan Plateau indicate that, when the upper crust movement is speedup in Tibetan Plateau and keeps the boundary condition unchanged, the energy stored in upper crust is released, the driving force by Indian plate increases the horizontal compression stress and movement in other layers in Tibetan Plateau, and increase the horizontal compression stress in the whole geosphere in North China area Comparing the disturbing distribution of horizontal compression stress in the upper mantle layer, the value in North China area is only about one twelfths of that in south part of Tibetan Plateau.

3青藏高原地区地壳非均匀活动在中国大陆岩石层引起扰动场的研究结果表明，在保持板块边界作用强度不变的情况下，青藏高原地区岩石层上部地壳运动的增强，增加了其岩石层下部的向前推挤，同时也增加了对其它块体的推挤作用，以上地幔盖层内最大水平主压应力的扰动值为例，华北地区比青藏高原南部地区小一个量级。
