Drill Collars are integral heavy-wall joints that are manufactured from a solid bar of modified alloy steel. The solid bars are quenched and tempered to obtain the required mechanical properties, then trepanned, drifted and threaded. All drill collars are heat-treated with hardness within 285 to 341 BHN, which are guaranteed one inch below the surface of the pipe. Lake Petroleum could supply slick type drill collar, spiral drill collar and Non-magnetic drill collar (NMDC).
Kellys are manufactured with one of two drive configurations, square or hexagonal. Square kellys are furnished as forged or machined in the drive section. Hexagonal or fully machined square kellys are machined from full length quenched and tempered round bars. Square Kelly and hexagonal kellys are fabricated as per requirements of customers. The kellys are made of AISI 4142H-4145H forged or rolled alloy structural steel. Quenching plus tempering thermal treatment will be conducted over the whole length. Its Brinell hardness can reach 285-341 on the basis of such thermal treatment. Charpy impact energy: >or =54J. The formulated process can ensure that the misalignment of the hole reaches the standard wall thickness. Kelly bars are manufactured according to API-7-1 Spec.
Lake Petroleum could supply a huge quantity of new drill pipe for sale, available in all standard sizes and weights, to quickly meet the drilling equipment needs of companies in the oil, gas and Geothermal industry.

Drill subs are an important integral part of everyday drilling. Not having the right thread adapter can make your life miserable. We have a large inventory of common and not so common sizes. Custom sizes are always available. Rotary subs have two primary applications. They can be used to cross over from one connection size to another, or as the disposable component used to extend the connection life of a more expensive drill stem member. Installing a float sub (with check valve) is always a good idea when drilling in wet situations.

DRILL RODS: The tool steel drill rod pieces (O-1, A-2, D-2, H-13, S-7, M-2, and W-1) are usually machined in the annealed state and then heat treated to make hardened, long lasting tools. The Applications Table below shows the classes, steel grades, hardening methods, and typical applications for Drill Rod. To use the table, find the class in the left column. To find out what is drill rod used for, find the steel grade in the table below and read the applications in the right column of the same row. DRILL PIPES: Available Ranges: Sizes : 3",3 ½", 4 ½" & 5 ½" Length : 5', 10', 13', 15', 20' & 30'
Drill Pipes A Drill Pipe is a tube shaped conduit made of steel that is fitted with specially made threaded ends that are known as tool joints.The Drill is hollow and thick walled tubing that is made of steel with a variety of uses. Pipe for drilling provides for the drilling of a well bore and is available in a number of sizes. Drill pipes also provide strength and weight and are typically 30 ft to 33 ft long

Drilling Tool Luhai drilling motor is a positive displacement motor. High pressure drilling fluid fl ows into the drilling motors, thereby enabling the hydraulic energy to be converted into mechanical energy, at the same time, the rotor drives the shaft and bit to rotate to achieve the purpose of drilling. Luhai produces LZ73, LZ89, LZ95, LZ102, LZ120, LZ127, LZ146, LZ165, LZ172, LZ185, LZ197, LZ203, LZ216, LZ244, LZ286 and other types of drilling motors. They are for drilling diameter of 88.9-660mm. Luhai also design and develop drilling motors with special sizes, different structural features and operating characteristics in accordance with the user's requirements, thus forming different varieties. At present, in addition to ordinary straight drilling motors, Luhai can also provide the following types of drilling motors 1. Bent drilling motors: The bent angle on the universal shaft can meet different kickoff requirement, there are single-bent and double-bent available. 2.Bent angle adjustable drilling motors: The bent angle of the drilling motors can be adjusted on well surface which enhance the extension of kicking off. 3.Extension drilling motors:On the basis of the ordinary drilling motor, improve motor torque to make the bit drilling quickly by increasing motor stage. 4.Hollow drilling motors: To meet the needs of high fl ow rate solids carrying in drilling, hollow rotors with carbide nozzles of different sizes are adopted, which can increase the input fl ow rate and the horsepower of drill bit.. 5.Drilling motors with high kick-off rate: Unique structural design, shorter body, bent point closer to the drill bit, and kick-off rate of up to >1°/m. 6.Saturated saltwater mud-resistant drilling motors:To maintain long time operation of drilling motors in saturated saltwater mud, special rotor coating is adopted to provide better corrosion and wear resistance. 7.High-temperature drilling motors: In order to improve the high temperature resistance of the stator rubber of the drilling motors, to meet the drilling requirements in high geothermal gradient region and deep and ultra-deep well drilling requirements, high-temperature resistant rubber is adopted to increase the temperature resistance of motor above 150 8.Sealed driving shaft drilling motors:The ordinary mud lubricated driving shaft is replaced with oil lubricated seal driving shaft, which improves the working conditions of the thrust and radial bearings, thus extending the service life of the drilling motors.
