地层的

A mong the thin-layer -sequence of 12 layers, the thickness of thinest layer is 5 meters.

其中在由12个薄层构成的薄层序列中最薄的地层厚度为5米。

The structure is a nose-shape monocline that descents toward the center of hydrocarbon occurring from the northwest to southeast. The distribution of oil and water in the Zhaowa-Anpeng Oilfield is relatively complex. There is deep-basin oil pool that the oil/water contact occurs at the updip end of the accumulation in the horizontal continuous reservoir. It is a tight-sandstone oil pool, the reservoir has a low permeance, and the formational pressure is lower than normal.

构造呈现单斜背景上的鼻状，自西北向东南生油中心倾没；赵凹安棚油田深层系内油水分布较为复杂，在横向连续储层内，出现了油水关系倒置的深盆油；储层属非均质低渗透储层；从深盆油观点看，属一种动态致密砂岩油藏；地层压力异常低，甚至负异常压力。

In this paper experiments of image segmentation on Quaternary strata are made on RS image by morphologic methods.

利用数学形态学的方法对遥感影像的第四系地层进行了影像分割实验。

The conventional development fashions for the gas condensate fields mainly are natural depletion and cyclic gas injection: using the method of gas injection require know clearly about the formation and need more investment, so this method is used few in our country; although a good deal of condensate oil is loss in the formation because of the appearance of retrograde condensation by the method of natural depletion, it is the main development method in China because of the lower investment and lower perception level abut the formation .

凝析气藏主要有衰竭或循环注气两种开发方式：注气开发对地质条件以及资金投入要求较高在我国仅有少数气田采用该方式：虽然采用衰竭开发方式大量的液态烃由于反凝析而损失在地层中，但是由于其低的投资费用、对地质认识程度要求不高，该方式在我国仍然是主要开发方式。

Attapulgite deposits are rare and valuable in the world. Large iodic attapulgite deposits with total reserves of 2 500 million tons were found in central and western Gansu Province. High iodine exists in attapulgite ores. There is about 0.0418% iodine in western attapulgite ore and 0.0425% in central ore, which are almost the same as the iodine content of niter in Chile.

凹凸棒石矿为稀有的非金属矿种，近年来，在甘肃中、西部第三纪地层中发现了大型凹凸棒石矿，矿石总储量可达2.5亿吨，矿石中碘含量较高，西部凹凸棒石含碘约为0.0418%，中部平均含量约为0.0425%，与智力碘硝石的含碘量（0.04%）相当。

Based on a comprehensive study of drilling and log data, sequences of short-term base-level cycle of turbidite fan in Yanchang Formation of Triassic in Longdong area are divided into three basic structure types: up - deepening non - symmetry, up -shallowing non ?symmetry and symmetry ones according to recognition sign of the interface of the short - term base - level cycle.

以高分辨率层序地层学理论和技术方法为指导，以钻井、测井资料的综合研究为基础，运用短期基准面旋回界面的识别标志将陇东地区三叠系延长组浊积扇短期基准面旋回层序划分为向上"变深"非对称型、向上"变浅"非对称型和对称型3种基本结构类型。

Downhole accidents frequently occurred due to the factors such as complicated formations, low automation degree of drilling equipments and nonproficiency of operation, and so on. High drilling cost or even the abandonment for a well will probably occur owing to those downhole accidents.

在钻井过程中，受地层多变性、钻井设备、仪器仪表自动化程度以及钻井操作技术熟练程度的制约和影响，井下往往会发生各种各样的复杂钻井事故，有的复杂事故会造成钻井成本急剧升高，甚至导致一口井报废。

Especially in nonresistant strata,in order to keep borehole wall stability we usually raise the drilling fluid density,but it seriously impede the rate of penetration.

尤其是不稳定地层，常常靠提高钻井液密度来保证井壁稳定，严重的制约了钻速的提高。

It is an intracontinental deformation system resulting from the structural stress caused by the collisions of the Huaiyu terrane moving westwards and the Cathaysia block moving northwestwards.

江南古陆与华夏古陆拼接带北西侧前震旦纪地层中存在着近东西向褶皱叠加在早期近南北向褶皱上的现象，这是怀玉地块向西拼贴、华夏古陆向北西碰撞拼接过程中构造应力向陆内传递时形成的构造变形系统。

Therefore it is very important to estimate production layer and determine planar distributions of reservoir dynamic permeability and press and residual oil.

因此对产层进行评价，确定地层动态渗透率等参数及剩余油的平面分布，由此研究其特点具有十分重要的意义。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
