Oil Drill Bit

The Purpose of drilling: drilling is an important link and means of exploration and development of petroleum and natural gas resources.


In petroleum geological work, the main purpose of drilling is to obtain the underground material data, that is, to obtain the core, ore core, cuttings, liquid, gas and other physical samples from drilling;




As a geophysical logging channel, it can obtain various geophysical data of underground rock and mineral layers.




As an artificial channel, it can observe the underground geological conditions and the underground fluid dynamics.




Using wellbore to exploit underground oil, natural gas, groundwater, geothermal resources.




The technique used in drilling boreholes for oil and gas exploration and development.




It mainly includes well design, selection of drill bit and mud, combination of drilling tools, coordination of drilling parameters, deviation control, mud treatment, coring, accident prevention, and treatment, etc.




The characteristics of diamond drill bit oil well technology are a deep hole, high pressure, high temperature, and many influencing factors.




According to the geological and geographical conditions and engineering needs of oil and gas exploration and development, there are two types of vertical Wells and directional Wells. The latter can be divided into general directional Wells, horizontal Wells, and cluster Wells.




The petroleum drill bits types include PDC bit and Tricone bit.




The PDC drill bits for oil and gas industry is also used in the most common petroleum drilling, which has high efficiency and stable effect.

GREAT has advanced optimized parameter drilling software, using electronic computer as the means, using optimization method, will affect the drilling speed of various controllable factors (such as drill bit type, bit pressure, rotation speed, mud performance, hydraulic factors), according to the minimum cost principle to establish a mathematical model, program.




Carry out optimization and coordination, so that drilling work to achieve high quality, fast, low cost.




Core extraction technology according to the design requirements from the hole drilling rock samples (core) required layer, for exploration and development of oil and gas reservoirs to obtain the first data.




Commonly used coring tools are mainly composed of Diamond core it, core barrel, core grab and joint, etc. During coring drilling, the drill bit continuously cuts the rock at the bottom of the well in a circular manner to make the drilled columnar core continuously enter the core barrel.




As the oil drill bit manufacturers, we provide the affordable oil well drill bit price. To meet special needs, there are also closed coring, pressure keeping coring and coring tools (rubber bushing coring tools) for extremely loose and broken formations.


As the great drill bits factory in china, Our brand is GREAT, founded in 2010, specialized in processing research of steel and diamond materials, is involved in the R&D, design, production, and sales of petroleum equipment, No-Dig. Up to now, we have to be the top material supplier of CNPC, SINOPEC, CNOOC. We have a 40,000 m² of production based in Hejian provincial development zone, Hebei, and several international advanced production lines featured in turning-milling compound, five-axis linkage, special for high-performance diamond processing, with the annual production capacity of more than 10,000 pcs. We provide the drill bits from 3″ to 36″, Rock reamer from 8“- 72“, Such as PDC bit, drill bits for rock and concrete, Tricone bit, Roller bit, Diamond Core bit, Bi-center bit, PDC reamer, Hole opener, etc.。


All our employees look like a big family and do our best effect to work hard and make our great drill bits. But also we all have a thankful heart, Firstly we thankful our customers choosing us, and we will supply our best service with great quality products. Secondly, we thankful we have a great team, they teach us and we bringing up from GREAT.
