The statistics show that most casing failures occur in argillaceous rock salt areas.

套管损坏是国内外油田普遍存在的问题，通过对江汉油田王广地区 30 0多口套管损坏井的资料进行了统计分析，得出套管损坏绝大多数发生在泥盐岩地层，套管设计载荷偏低，高压注水是加剧套管损坏以及射孔是射孔段套管损坏的主要原因，并针对泥盐岩的特点分析了套管损坏的机理。

The strata inside and outside the cave are argillaceous bedded limestone and wormkalks of late Cambrian, that is, 490—500 million years before present.

洞内外地层为距今4.9亿年—5亿年的晚寒武世泥质条带灰岩和竹叶岩状灰岩，它们都是在浅海中生成的，说明当时鱼谷洞地区曾是一片大海。

Red terrene and grey terrene are the main compositions of the Badong formation. The former (section 2 and 4) is mostly composed of elastic rock or arenaceous argillaceous rock and the latter (section 1, 3 and 5) is mainly composed of carbonate rock.

红色与灰色是巴东组地层的两大基本色调，红色系列的岩层，多见为碎屑或砂泥质岩类，而灰色系列的岩层，多见为碳酸盐岩类。

The lithology is a slight deterioration during the Cambrian argillaceous limestone strata.

其岩性是一种轻微变质泥质灰岩地层时代为寒武纪。

The Pb-Pb isochron of metamorphic argillite in Shuangqiaoshan Group is 1 490±68 Ma, while the Nd mode ages of Zhanggongshan Group, Shuangqiaoshan Group, Chenglang Group and Xiushui Group are 1.57 Ga, 1.89 Ga, 1.77 Ga, 1.60 Ga,respectively, less than 1.6-1.9 Ga, which suggest that they formed in Middle Proterozoic Subera.

研究结果还显示，双桥山群变质泥质岩的Pb-Pb等时线年龄为（1 490±68）Ma，而障公山群、双桥山群、程浪群和修水群的钕模式年龄分别为1.57 Ga、1.89Ga、1.77Ga和1.60 Ga，均分布在1.5～1.9 Ga之间，表明这些地层的形成年龄应小于1.9 Ga，是中—晚元古代的产物，同时表明扬子古陆南缘存在古元古代的基底。

Among all sequence strata of exploration target, it mainly developed medium-coarse clastic arkose in high water system, which overlies and underlies the primary sequence interface as well.

在各勘探目的层层序地层内，主要发育于高水位体系域中中粗粒岩屑长石砂岩发育带，同时也主要位于主要层序界面上下。

In go when country layer artesian well, often can happen to malign well leaks and break down collapse accident.

在潜山地层钻井时，往往会发生恶性井漏和垮塌事故。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
