drilling “钻孔” drill"钻进、钻入”

土木工程中,drilling和boring的区别和翻译

两个单词是有区别的,I think it"s the same as the difference between a rock and a stone。你可以drilling出一个孔,然后在这个基础上boring它(就是扩孔)。所以drilling叫钻孔,boring叫挖井。而且drilling比较强调过程,boring比较强调精确度。以上为个人见解

英语高手进 相互学习哦 The machine is drilling a hole.

the 是特指,a是指“一个”的意思。英语中名词前有几种情况,可数名词单数时,要有定冠词the或不定冠词a和an修饰;可数名词复数时,可以不用定冠词the或不定冠词a和an修饰;如果是不可数名词,也可以不用定冠词the或不定冠词a和an修饰。这句话是主系表的结构,主语为The machine 系动词 is 系动词后的成分就做表语drilling a hole。要注意,这不是主谓宾的句型,主要是看这句话的动词,即系动词be, become, appear, seem,look,sound,feel,get,smell等词,而系动词后的成分就相应的成为了表语。如she buy a apple。这句话中,buy不是系动词,所以a apple就不可以说是表语,它应是宾语

Rotary Drilling

Rotary drilling is a method used to drill deep boreholes in rock formations of the earth"s crust. This method is comparatively new,having been first developed by a French civil engineer,Rudolf Leschot,in 1863. The method was initially used to drill water wells using fresh water as the circulation fluid. Today this method is the only rock drilling technique used to drill deep boreholes ( greater than 3000 ft) . It is not known when air compressors were first used for the drilling of water wells,but it is known that deep petroleum and natural gas wells were drilled utilizing portable air compressors in the 1920"s . Pipeline gas was used to drill a natural gas well in Texas in 1935 using reverse circulation techniques.Today rotary drilling is used to drill a variety of boreholes. Most water wells and environmental monitoring wells drilled into bedrock are constructed using rotary drilling. In the mining industry rotary drilling is used to drill ore body test boreholes and pilot boreholes for guiding larger shaft borings. Rotary drilling techniques are used to drill boreholes for water, oil,gas,and other fluid pipelines that need to pass under rivers,highways,and other natural and man-made obstructions. Most recently,rotary drilling is being used to drill boreholes for fiber optics and other telecommunication lines in obstacle ridden areas such as cites and industrial sites. The most sophisticated application for rotary drilling is the drilling of deep boreholes for the recovery of natural resources such as crude oil,natural gas,and geothermal steam and water. Drilling boreholes for fluid resource recovery requires boreholes drilled to depths of 3000 ft to as much as 20000 ft.Rotary drilling is highly versatile. The rotary drilling applications given above require the drilling of igneous, metamorphic, and sedimentary rock. However, the deep drilling of boreholes for the recovery of crude oil and natural gas are almost exclusively carried out in sedimentary rock. Boreholes for the recovery of geothermal steam and water are constructed in all three rock types. The rotary drilling method requires the use of a rock cutting or crushing drill bit.To advance the drill bit in rock requires the application of an axial force on the bit ( to push the bit into the rock face) , torque on the bit ( to rotate the bit against the resistance of the rock face ) ,and circulating fluid to clear the rock cuttings away from the bit as the bit generates more cuttings with its advance ( Figure 14. 1) .Figure 14. 1 The three necessary components for rotary drillingRotary drilling is carried out with a variety of drilling rigs. These can be small “single”rigs,or larger “double” and “triple”rigs. Today most of the land rotary drilling rigs are mobile units with folding masts. A single drilling rig has a vertical space in its mast for only one joint of drill pipe. A double drilling rig has a vertical space in its mast for two joints of drill pipe and a triple drilling rig space for three joints. Table 14. 1 gives the API length ranges for drill collars and drill pipe.Table 14. 1 API length ranges for drill collar and drill pipeSingle rigs can be fitted with either an on-board air compressor,or an on-board mud pump. Some of these rigs can accommodate both subsystems. These rigs have either a dedicated prime mover on the rig deck, or have a power-take-off system which allows utilization of the truck motor as a prime mover for the drilling rig equipment ( when the truck is stationary) . These small drilling rigs provide axial force to the drill bit through the drill string via a chain or cable actuated pull-down system,or hydraulic pull-down system. A pull-down system transfers a portion of the weight of the rig to the top of the drill string and then to the drill bit. The torque and rotation at the top of the drill string is provided by a hydraulic top head drive ( similar to power swivel systems used on larger drilling rigs) which is moved up and down the mast ( on a track) by the chain drive pull-down system. Many of these small single drilling rigs are capable of drilling with their masts at a 45° angle to the vertical. The prime mover for these rigs is usually diesel fueled.Typical double rigs have the capability to drill to depths of approximately 10000 ft and are used for oil and gas drilling operations,geothermal drilling operations,deep mining and geotechnical drilling operations,and water wells. Double rigs typically use Range 2 drill collars or drill pipes. These rigs are fitted with an on-board prime mover which operates the rotary table,drawworks,and mud pump. The axial force on the drill bit is provided by drill collars. The torque and rotation at the top of the drill string is provided by the kelly and the rotary table. The double drilling rigs have a “crows nest”or “derrick board”nearly midway up the mast. This allows these rigs to pull stands of two drill collars joints or two drill pipes joints. These rigs can carry out drilling operations using drilling mud ( with the on-board mud pump) or using compressed air or gas drilling fluids ( with external compressors) . A fewof these drilling rigs are capable of drilling with their masts at a 45° angle to the vertical. The prime mover for these rigs is usually diesel fueled,but can easily be converted to propane or natural gas fuels.Triple drilling rigs are available in a variety of configurations. Nearly all of these drilling rigs are assembled and erected from premanufactured sections. The vertical tower structure on these drilling rigs is called derricks. The smaller triple land rigs can drill to approximately 20000 ft and utilize Range 2 drill collars and drill pipes. Very large triple drilling rigs are used on offshore platforms. These rigs can utilize Range 3 drill collars and drill pipes.The schematic layout in Figure 14. 2 shows a typical self - propelled double drilling rig. This example rig is fitted with a mud pump for circulating drilling mud. There is a vehicle engine that is used to propel the rig over the road. The same engine is used in a power-take-off mode to provide power to the rotary table,drawworks,and mud pump. For this rig,this power-take-off engine operates a hydraulic pump which provides fluid to hydraulic motors to operate the rotary table,drawworks,and mud pump. The “crows nest”on the mast indicates that the rig is capable of drilling with a stand of two joints of drill pipe. This drilling rig utilizes a rotary table and a kelly to provide torque to the top of the drill string. The axial force on the bit is provided by the weight of the drill collars at the bottom of the drill string ( there is no chain pull-down capability for this drilling rig) . This example schematic shows a rig with on- board equipment that can provide only drilling mud or treated water as a circulating fluid. The small air compressor at the front of the rig deck is to operate the pneumatic controls of the rig. However,this rig can easily be fitted for air and gas drilling operations. This type of drilling rig( already fitted with a mud pump) ,would require an auxiliary hook up to external air compressors to carry out an air drilling operation. Such compressor systems and associated equipment for air drilling operations are usually provided by a subcontractor specializing in these operations.Figure 14. 2 Typical self-propelled double drilling rig schematic layout

是不是你新建的文件名或打开的文件名叫Drilling,如果是就跟钻孔的模板文件同一个名字冲突了。

DRILLING的汉语意思是什么

如图

drilling是什么意思

drilling的意思是:钻孔。钻孔是指用钻头在实体材料上加工出孔的操作。这里讲述了勘探工作里的钻孔工作,以及钻孔需要的辅助工具以及部分应急措施方法。在地质勘查工作中,利用钻探设备向地下钻成的直径较小深度较大的柱状圆孔,又称钻井。钻探石油和天然气以及地下水的钻孔直径较大些。钻孔直径和深度大小,取决于地质矿产埋藏深度和钻孔的用途。通常指用尖锐的旋转工具在坚硬的物体上钻穿。如:在木板上钻孔。在数处给一块金属板钻孔。用凿岩机钻孔洞。在花岗岩上钻孔。指为了装饰、识别或便于分开而打一排小孔或花样。形似独木舟有时钻孔作为垂饰的船形宝石。用钻头在实体材料上加工孔叫钻孔。各种零件的孔加工,除去一部分由车、镗、铣等机床完成外,很大一部分是由钳工利用钻床和钻孔工具(钻头、扩孔钻、铰刀等)完成的。在钻床上钻孔时,一般情况下,钻头应同时完成两个运动。主运动,即钻头绕轴线的旋转运动(切削运动);辅助运动,即钻头沿着轴线方向对着工件的直线运动(进给运动),钻孔时,主要由于钻头结构上存在的缺点,影响加工质量,加工精度一般在IT10级以下,表面粗糙度为Ra12.5μm左右、属粗加工。
