Based on indoor measurement of rock acoustic velocity,drillability, rigidity ,uniaxial compressive strength,the relationship between acoustic velocity and fragmentation parameters of rocks and that between the surface acoustic velocity and the underground mine logging acoustic velocity were explored by regression analysis.

在室内测定岩石声波速度、可钻性、硬度、单轴抗压强度试验的基础上，利用回归分析方法，探索声波速度与岩石机械破碎性能参数之间、地面声波速度与井下测井声波速度之间相关关系，建立了利用测井声波速度预测地层岩石机械破碎性能参数的数学模型，介绍了预测剖面及资料验证结果，并将这一方法用于计算PDC钻头可钻性以及中国南方海相碳酸盐岩地层的岩石力学参数。

The velocities of ultrasonic wave and rock drillability are measured in perpendicular and parallel directions of the bedding plane of core samples which were cut from the approach hole of Chinese continental scientific drilling. Rock drillability index and P-wave velocity anisotropy coefficient are calculated from the testing data; and the results are discussed.

通过室内实验分别测定了岩芯垂直于和平行于地层层面方向的可钻性及声波速度，得到了岩石可钻性各向异性指数和波速各向异性系数，并对结果进行了讨论。

The colour photo shows the new ultrasonic driller/corer penetrating a sandstone while the drill is held only from its power cord.

彩色照片显示，这种新型的超声波凿岩机/岩芯钻取器穿透了一块砂岩，而钻小得只能通过它的电源线来支住它。

Oil exploration practice and researched results indicate that most of hydrocarbon reservoir forming related to gyp- sum and salt rock formation,and the hydrocarbon is also associated with it,so,successfully drilling through gypsum and salt rock formation has been become one of drilling dif- ficult problems.

石油勘探实践和研究结果表明，许多油气藏的形成都与膏盐岩地层有关，也常与膏盐岩地层伴生，成功钻穿膏盐岩地层是钻井难题之一，录井技术成为钻进安全监测、膏盐岩地层准确预报的重要手段。

According to the features of fracture and vug carbonate reservoir in the Tahe oilfield,application effects of horizontal and side wells are analyzed in terms of development practice s such as well design,parameter details and development effect.

针对塔河油田碳酸岩岩溶洞裂缝型油藏特点，从水平井的部署、设计、参数优化、开发效果及利用水平井挖潜等开发实践方面，总结了水平井和侧钻水平井在本油藏的应用情况后得出：利用水平井开发并非塔河碳酸盐岩油藏开发唯一的选择和最佳选择；水平井相对于直井开发的优越性在该油藏并未得到充分体现；因此认为在储层预测、流体识别和缝洞系统定量描述满足不了水平井设计要求时，不易大规模实施水平井开发，尤其是对于复杂特殊性油藏更是如此。

The physical chemistry properties of evaporite beds in Bachu area are analysed.On the basis of the feature of salt beds,the undersaturation salt water drilling fluid is determined.

塔里木盆地复合盐层地层分布广，在不同构造的钻探中都钻遇盐层，盐层厚度一般几十米到几百米，岩性以盐岩与膏岩、泥岩、泥质粉砂岩等不等厚互层。

As for the air percussive rotary drilling, because of its advantages of high ROP, long bit life, light WOB, reduced wear of drill collar, large cuttings, low drilling cost, low formation damage and no lost circulation, it has gained acceptance.

空气冲击回转钻井在一些特定的地层和井眼条件下具有高机械钻速、长钻头寿命、小钻压、较轻钻具磨损、大岩屑、低钻井成本、较轻油层污染和避免井漏等优点，因此很早就被钻井界接受。

我厂集产品开发，生产制造及产品销售与服务于一体，通过引进，吸收，开发，创新，采用专业技术生产的自钻式中空注浆锚杆系列产品及专用配套机械(潜空钻，凿岩机，注浆机，喷射机，注浆泵，锚杆机等)广泛应用于地下工程（交通隧道，水工隧道，矿山巷道和各类用途的锚固支护）岩土工程（边坡，堤岩，深基坑的锚固支护）修复加固工程（隧道，海堤，大坝，房屋建筑）。

The research shows that there is not any published article introduce stablizer that used in gas drilling, thus there is no evaluation about the conventional auger drill stabilizer's impact on cutting-carrying and lifting ability of the annulus gas.

调研发现，公开发表的文献中，目前没有文章介绍专用于气体钻井的钻柱稳定器，也没有就气体钻井使用常规螺旋钻柱稳定器对环空气体携岩举升能力造成的影响进行评价。

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。
