The downhole motor is a kind of downhole power frilling tool by mud. The mud output by the mud pump will enter the motor through the bypass valve, and a certain pressure difference will be formed at the inlet and outlet of the motor, to push the rotor of the motor to rotate, and transfer the torque and the RPM to the drill bit via the universal shaft and the driving shaft.

• Increased rate of penetration.
• Better hole deviation control.
• Reduction in drill string failure rate.
• Reduction in wear and tear of the swivel, Kelly, and rotary drives.
• Reduction in fuel cost, since compared to rotary drilling, less energy is required to power a downhole motor.
• Big torque, high effective, wide flow rate range, running stable and long using time.

Drill Collar is the basic component in the BHA which provides weight on the bit for drilling and keeps the drill string in tension.  JX Petro Drill Collar is manufactured from AISI 4145H modified quenched and tempered steel and is heat treated along its entire length for uniform toughness and durability. Strict metallurgical tests are performed per specifications to ensure that the heat treatment produces consistent and maximum hardness through the depth of the bar.

• Hardness range of 285 to 341 BHN and a Charpy impact value of 40ft/lbs is guaranteed for evenly distributed 16 points in any cross sections at room temperature.
• Connections as phosphate coated father machining to protect the threads from corrosive elements and to prevent galling upon initial make-up. Thread roots are cold rolled on API and H0-90 connections.
• Pressed steel thread protectors are supplied to all drill collars that is equipped with standard connections.
• Manufactured strictly according to API standards.
• Widely used in oil, gas, HDD, and a geothermal field.

Kelly is the main driver of the whole drill string. It transmits torsional energy from the rotary table through the drill string to the bit at the bottom of the hole. Petro Kelly is a long square or hexagonal, precision machined heavy steel bar that is supported by the swivel through the rotary table and is connected to the first joint of the drill pipe in the drill string. The flats are precision-milled to API specifications. All milling processes are performed on specially designed rigid Kelly mills to ensure tight tolerances and high-quality drive sections. Each Kelly is furnished with pressed steel thread protectors.

Full Opening Safety valve ( FOSv) is a ball-type safety valve used to stop flow through the drill string when the drill string is being withdrawn from the well. FOSv is a dual body full-opening safety valve, that does not interfere with the running of tools such as core barrels or survey instruments. It is designed to be stabbed into the top joint of drill pipe or tubing string at the rig floor and closed quickly in case a well kicks.

• Available with a wide variety of sizes and end connections
• Operating wrench and thread protectors included
• Major repair kits available for every valve
• Comes with certified test report
• Identifiable open and close markings
• Can be H2S corrosion resistant as per NACE MR0175

Float valve Sub is an important tool in petroleum exploration and drilling engineering. The float valve sub is connected at upper part of drill bit. The float valve sub is near the bit connecting thread. The float valve sub can also be used at different necessary position of drill string when required. The main application is, when connected with single piece pipe, it prevents mud from coming in and up blocking the hole. When blowout takes place, blowout in drill string will be avoided because nozzle is closed automatically by valve cap of the float valve assembly. The working pressure of float valve is supposed to be 5000psi or 10000psi. Float valve sub has two types:

• Available with a wide variety of sizes and end connections
• Operating wrench and thread protectors included
• Major repair kits available for every valve
• Comes with certified test report
• Identifiable open and close markings
• Can be H2S corrosion resistant as per NACE MR0175

Heavy Weight Drill Pipe ( HWDP) is an intermediate weight drill stem component that is used in conjunction with the drill pipes and drill l collars.   HWDP is available in standard, spiral, and nonmagnetic designs. In some applications, heavy-weight drill pipes also can be used instead of the drill collars.Our HWDP is made from one-piece AISI 4145H modified quenched and tempered steel. It is designed for tough drilling environments in vertical and directional wells. HWDP is a transition member between drill collar and drill pipe. For directional holes, HWDP provides weight on-bit and additional stiffness to prevent buckling.

• Made of 4145H alloy structural steel.
• Production complies with the provisions under the Standard SY/T 5146-1997. Connector screws comply with the provisions of the Standard API SPEC 7-1.
• The tube section has a larger diameter at mid length to protect the heavy weight drill pipe from wear.
• Hardbanding and Internal Coating can be provided on customer’s request.

When the drill tool is lifted out of the hole, a blowout could happen due to suction. In event of a blowout, the open position of the IBOP valve allows backflow, easing the installation process. Upon successful installation, the valve can be promptly closed with a relief rod to prevent further backflow. Fluid can then be pumped in from the surface to discharge the IBOP and drill string. The purpose of blowout prevention can be achieved by the following generic steps: discharging the relief sub; regulation of fluid; commence pump circulation.We produce H2S resistance Inside Bop Valves, which adopt high-quality import sulfur-resistance material.

Kelly valve is a manually operated ball-type valve for the drill stem, divided into upper and lower sections. The upper Kelly valve is connected between the lower end of the swivel and the upper end of Kelly. The lower Kelly valve is connected between the upper end of the drill pipe and the lower end of Kelly or the lower end of Kelly saver subs. The Kelly valve can be opened or closed off by simply turning a special operating wrench 90° according to the indicated direction.

• Available with a wide variety of sizes and end connections
• Two piece body with full drift bores
• Operating wrench and thread protectors included
• Major repair kits available for every valve

A drill bit is a device attached to the end of the drill string that breaks apart, cuts or crushes the rock formations when drilling a wellbore, such as those drilled to extract water, gas, or oil.The drill bit is hollow and has jets to allow for the expulsion of the drilling fluid, or mud, at high velocity and high pressure to help clean the bit and, for softer formations, help to break apart the rock.

• API 7-1 Standard connection
• Tricone bit is suitable for any rock formation.
• Tricone bit is versatile and can handle changing formations.
• PDC Main cutters are high performance PDC cutters to insure service life of the bit while improving ROP.
