砂屑的

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。

Physical simulation of clastic sedimentary system is an important resort of studying sedimentary process,it is also one of efficient methods of forecasting oil-gas sandbody distribution.

碎屑沉积体系的物理模拟是研究沉积过程的重要手段，也是预测油气储集砂体分布的有效方法之一。

Firstly, the volcanics and shaly sand were separated with FMI static images and conventional logging data. Then, the image characteristics of all typical volcanics were analyzed with the dynamic FMI images to establish the FMI image patterns of volcanic lava (including rhyolite, dacite, andesite, and basalt) and volcaniclastic rock (including volcanic breeds and tuff).

首先利用FMI静态图像和常规测井曲线将砂泥岩与火山岩区分开来；然后利用FMI动态图像分析了火山岩各种岩性的图像特征，归纳总结出火山熔岩类（流纹岩、英安岩、安山岩、玄武岩）和火山碎屑岩类的FMI图像模式。

Studies show that it is a set of turbidity sedimentary under the condition of deep-water environment in rift deep depressing period with the characteristics of multiphase and mutability, The lithology of reservoir is chiefly mid-fine grained conglomerate and lithic mixed sandstone, as well as the gravel-bearing sandstone next. Sand bodies in the plane are controlled by water channel obviously, resulting in NW-oriented banded distribution.

研究表明，大凌河油层是裂谷深陷期深水环境条件下形成的一套浊流沉积物，沉积物具有多期性和突变性，主要岩性以中－细砾岩和岩屑质混合砂岩为主，次为含砾砂岩，砂体在平面上受水道控制明显，呈北西向的条带状展布。

When palaeoclimate became arid, the content of authigenic carbonate increased, and the proportion of aeolian silty sand in terrigenous clast increased distinctly too.

在高频旋回中，当气候偏干旱时，页岩中的自生碳酸盐含量增加，同时风成粉砂在陆源碎屑中所占的比例也明显升高。

Its food mainly consisted of various smal l planktons and organical fragments and the animals had no obvious kind selectio n of food.

营埋栖生活，潜居砂质底，洞穴的深度与贝类长度相当，依靠水交换滤取食物，饵料以各种小型浮游生物及有机碎屑为主，对种类没有明显的选择性。

The fold cambers in plane which protrudes to the south. Regional tectonic pattern show bigger hiberarchy, which mainly is composed of roof -slippage-fault-fold. The tectonic pattern of shallow hiberarchy which includes middle-upper Triassic's fragmentary rock is fault-propagation and low-angle faults fracture, its roof rock is mainly pelyte. The tectonic pattern of midding-deep hiberarchy which includes upper Paleozoic's carbonatite is possibly thrust and broad-tempered fold.

研究区的构造样式表现出较大的层次性，总体为盖层滑脱式逆冲褶皱型，其中，以中、上三叠统碎屑岩为主的浅层次，其构造样式主要为紧密型断滑或断展褶皱低角度逆冲断裂，其滑脱面为三叠系下部泥质岩或粉砂质泥岩；以上古生界碳酸岩为主的中深层次，其构造样式推测以冲断和宽缓褶皱为主。

During well drilling, LWD monitoring device, comprehensive logging device, cutting logging, seismic interpretation, geologic models, and many other technical measurements had been used for real-time monitoring and comprehensive analysis. What had been done helped geosteering, and the putting forward of drilling track. The horizontal wells drilled in ultra thin single sand layer with the thickness of less than 2m, and the penetration rate for sandstone was higher.

在现场钻井过程中，采用LWD监控仪、综合录井仪、岩屑录井、地震解释、地质模型等多种技术手段相结合，实时监控，进行综合分析，为地质导向提供依据，并准确地指导了钻井轨迹运行，实现了在不到2m的超薄单砂层中穿行，达到了较高的砂岩钻遇率，并成功的穿越了小断层，实现了二次着陆。

Nowadays, sheet pile wall has been widely used in the field of civil engineering.

桩板墙在土木工程领域应用较为广泛，但在粒状碎屑溜砂坡防治工程中的应用却不多。

The Xujiahe formation in south Sichuan basin is featured by continental clastic sedimentary, thin sand mud interbed, and the welldeveloped sandstone in this area, however, its lithology is tight and its physical properties is poor. In the case of gas bearing, the acoustic velocity difference between the sandstone and the shale is too little to make clear responses on seismic data, as a result, it is very difficult to conduct the gasbearing prediction and to analyze the gasbearing range distribution by means of conventional impedance inversion and hydrocarbon detection.

四川盆地蜀南地区上三叠统须家河组为一套砂泥岩互层的陆相碎屑岩沉积，砂岩发育，但岩性致密，物性较差，砂岩储层含气后的速度与页岩速度相差不大，在地震剖面上无明显的响应，因而采用常规波阻抗反演和含气检测技术不能有效解决该类含气储层识别问题和含气范围展布问题。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
