In many of the modern rigs, a rack will vertically hold various sections of drill pipe along the side of the derrick. Each is then added to the drilling string as the bit 

been completed and is used to control the flow of oil and gas. Circulate (v): to cycle drilling fluid through the drill string and wellbore, returning to the mud pits. Oil Rig. Your rigs, pipes and oilfield tubulars are vulnerable to corrosion, cracking , third-party damage and manufacturing flaws. Our rig inspection, drill pipe  As drilling proceeds, and the well gets deeper, the drilling crew adds new sections of drill pipe to the ever-lengthening drill string. Hydraulic devices keep constant  Find out more about how a drilling company locates and drills for oil or gas, using rigs, The drill is rotated by a top drive on the rig floor, and as the drill string is 

of drill pipe materials, and the corrosion challenges that need to be overcome for drilling ultra-deep oil and natural gas wells. Keywords deep drilling 

Drill string consists of various drill string components, we will discuss about every drill string components and their functions. without drill string there is no concept of drilling. Drill swivel - large handle that holds the weight of the drill string; allows the string to rotate and makes a pressure-tight seal on the hole. kelly - four- or six-sided pipe that transfers rotary motion to the turntable and drill string. turntable or rotary table - drives the rotating motion using power from electric motors. The drillstring means the tubulars and the accessories used to run the drill bit to the bottom. The drill string is composed of drill pipe, heavy weight drill pipe, drill collars and other components like stabilizers and drilling jars. Degasser (not pictured) is a device that separates air and/or gas from the drilling fluid. It is typically mounted on top of the mud tanks. Derrick (#14) is the support structure for the equipment used to lower and raise the drill string into and out of the wellbore. This consists of the sub-structure A drill string on a drilling rig is a column, or string, of drill pipe that transmits drilling fluid (via the mud pumps) and torque (via the kelly drive or top drive) to the drill bit. The term is loosely applied to the assembled collection of the smuggler pool, drill collars, tools and drill bit. Introduction to Rig Types and Basic Drill String Components The first Oilwell Drilling module covers basic oil and gas well drilling principles. Different types of drilling rigs are presented, the difference between a kelly/rotary table and a top drive system is explained, and the components of a drill string are described in detail.

Such a drill string would be used on large drilling rigs. At the bottom of the drill string is the drill bit. The drill bit is threaded (made-up) to a bit sub. The drill bit has

Downhole Oil Tools, Inc. provides Slick Drill Collars Or Spiral Drill Collars, manufactured from 4145H MOD Q&T steel with a hardness range of 285-341 BHN. The drillstring means the tubulars and the accessories used to run the drill bit to the bottom. The drill string is composed of drill pipe, heavy weight drill pipe, drill collars and other components like stabilizers and drilling jars. Used to rotate the drill string during the drilling process, the top drive is a motor that is suspended from the derrick, or mast, of the rig. These power swivels boast at least 1,000 horsepower Drilling | Offshore Drilling Rigs Many of the world’s potential reserves of hydrocarbons lie beneath the sea, and the hydrocarbon industry has developed techniques suited to conditions found in the offshore, both to find oil and gas and to successfully produce it.
