地层

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。

In steep rock strata, where the strata sequence is normal and the gentle section is lack of a large number of strata

在岩层陡区，层序正常，缓区断面缺失大量地层的情况下

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。

As for coseismic deformation of Chi-Chi earthquake, the footwall of Chelungpu Fault moved southeastwards 0.3-1.5 m, and the value was increasing toward the fault; the hanging wall moved northwestwards 1.4-7.0 m, but the value was smaller south of the Choshui River. After the Chi-Chi earthquake, the hanging wall of Chelungpu Fault was still moving west-northwestwards and kept uplifting, while the footwall gradually changed direction from ESE to WSW or even WNW, clockwise resuming to inter-seismic deformation pattern. It is interesting to notice that despite the largest coseismic deformation in the northernmost segment of Chelungpu Fault, the post-seismic deformation peaked around the epicenter of Chi-Chi earthquake.

集集地震之同震变形，在车笼埔断层下盘向东南方向位移0.30~1.5 m，且越靠近断层位移量越大；车笼埔断层上盘则向西北方向大幅位移约1.4~7.0 m，浊水溪以南的位移量较小；集集地震以后之震后变形型态，以车笼埔断层为分界，上盘在震后向西北西方向位移的型态仍与同震时相同，下盘由同震时一致性的向东南东方向，逐步向西北西或西南西方向位移，亦即在车笼埔断层下盘有逐步依顺时针方向回归至震间的滑移型态；另就位移速率而言，虽然同震变形最大地区在车笼埔断层北端，但其震后的变形量最大地区，却集中於震央位置附近；就地震循环而言，震后的6年期间仍处於地层压密重整阶段，尚未回归至该区震间阶段的位移状态。

In this paper, for the data character of exploring and developing area in oil-area, I propose a sub-area, multi resolution and level model and create effective management mechanism on stratum grid data organization with index managing and organizing data linear octonary trees.

本文针对油气田的勘探、开发领域的数据特点，提出了分块的多分辨率层次模型，结合线性八叉树索引管理和组织数据，建立有效的地层网格数据组织管理机制。

One that is held over, especially an officeholder who is retained after an expired term of office.

还有一直挖通到下面的地层的鼠洞，后被继发的洪水所填满。

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。

Thus a complete section of stratigraphic sequences from Oligocene to Quarternary is obtained, showing 5 second order sequences and 20 third order sequences.

自 1985年起，中国海洋石油东部公司微体古生物分析鉴定人员对珠江口盆地近 5 0口钻井的有孔虫化石进行了定量统计，为高分辨率生物地层划分与对比提供了丰富的资料。

In the second formation of the Langshan group in the Dongshengmiao polymetallic pyrite deposit, metamorphic basic volcanic rock s have been discovered,except quartz keratophyre, with a blastoporphyritic texture containing albite and oligoclase and minor, pyroxen and hornblende.

东升庙硫－多金属矿床狼山群二组含矿地层中，除已发现的变质石英角斑岩之外，又找到具有变余斑状结构（斑晶主要为钠质斜长石，另有少量辉石和角闪石）的变质基性火山岩和变质凝灰岩夹层以及火山岩屑与晶屑。

In these curves, the apexes are one to one correspondence with the reservoir oil-water interfaces.
