This paper integrates the engineering fact, founding models for calculating and analyzing, including the thereinafter several aspect:This paper founds a model for load on a rod in deviated well, according to the theory of rod designing put forward by American Petroleum Institute, doing research on the program realization of the designing sucker-rod.

本文结合工程实际，对有杆抽油系统进行建模计算和分析，主要包括以下几个方面的内容：(1)建立了斜井抽油杆柱载荷计算数学模型，按照修正的美国石油学会抽油杆柱设计理论，研究了斜井抽油杆柱的设计方法的具体实现。

Then the migration was mainly driven by buoyancy in adjusting periods of reservoir after Neocene, it is difficult to form high continuous oil column, because of the reservoir bed being over tight.

提出了古近纪前、后的&跷跷板&式成藏模式，即明水期—古近纪油气主要由源区向西南方向运移，而新近纪后的油气运移主要靠浮力驱动，但因储层已致密化，难以形成较高的连续油柱，油、水的分异程度低。

When the protruding part of the cam switch over, the role of force in the spring, the plunger downward movement, the upper plunger space have a vacuum, when the plunger on the end to put the plunger into the After the open hole, filled with oil in the upper body inside pump diesel pump oil through hole into the room, plunger movement to the next stop point, the end into the oil.

当凸轮的凸起部分转过去后，在弹簧力的作用下，柱塞向下运动，柱塞上部空间产生真空度，当柱塞上端面把柱塞套上的进油孔打开后，充满在油泵上体油道内的柴油经油孔进入泵油室，柱塞运动到下止点，进油结束。

The visco?-elastic fluid hydrodynamic theory was applied to the wear-resistance experiment on sucker rods.The values of normal stress in suck string generated by visco?-elastic fluid and eccentricity brought out by sucker string were measured quantitatively.The partial abrasion of sucker string and tube in oil well was caused from the normal stress of visco?-elastic fluid.A module for bending analysis of sucker rod in cross direction and wire direction was developed.

大庆油田实施聚合物驱油以后，出现了抽油杆受力状况恶化、抽油杆柱严重偏磨的现象，为此开展了粘弹性流体水动力学理论和试验研究，得出了粘弹性流体在抽油机井筒内的流动规律及对抽油杆柱法向应力的影响规律，定量测出了粘弹性流体对抽油杆柱的法向应力值和抽油杆柱产生的偏心率。

With 4 cavities, for example, generally, the left and right chamber of the oil column in the 20 ~ 25mm between hole diameter of 0.25 ~ 0.4mm.

以4腔为例，一般下、左、右腔的油柱在20～25mm之间，小孔直径为0.25～0.4mm。

The oil chamber when the spindle is not installed, all the oil out of the mouth of the oil column must be consistent, if not, should be taken to change the restrictor aperture approach, to change its flow.

各油腔在不装主轴时，各个出油口的油柱必须一致，若不一致，应采取改变节流器孔径的方法，改变其流量。

On the basis of study of fault seal history, together with the obtained achievement of structural stress field and fluid potential field, it is discovered that for the pool-forming process of oil and gas in the studied area the fault seal of nowadays is better than that of the Ed and Ng stages, it plays an important role to determine the oil column height and hydrocarbon preservation.

在断层封闭史研究的基础上，结合构造应力场及流体势场的研究成果，揭示了研究区油气的成藏过程，阐明了现今断层的封闭性优于Ed、Ng期断层的封堵性，并对油气的保存以及油柱高度的最终定型具有重要意义，而Ed、Ng期断层的封闭性对油气的分布态势有重要的影响。

Biodegradation is a dynamic process, where the diffusion of hydrocarbon to oil water contact, the diffusion of metabolites away from the reaction site to the oil column. Late charging and mixing occurred in the reservoir also control on the degree of biodegradation.

生物降解是一个动态过程，烃类不断向油水界面扩散，降解过程中新形成的代谢物从油水界面向油柱扩散，后期充注及油藏内的混合作用也是控制生物降解作用程度的重要因素。

While the current features of fault seal decide the conservation of reservoirs and heights of oil accumulations.

现今断层的封堵性则对油气的保存以及油柱高度的最终定型起到了重要作用。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
