GF PDC Bit

PDC drill bit is a new type of cutting bit made by artificial polycrystalline diamond cutting inserted

on bit matrix. It has sharp, high wear -resistance and self- sharpening diamond as its original cutting

parts, which can get high drilling depth in low drilling pressure. It is much safer than teeth wheel drill

bearing, which can greatly improve the work efficiency and reduce the cost of well drilling.

Model LZ Downhole Motor

Model LZ Downhole Motor is a kind of downhole dynamic drilling tool upon the power of

drilling mud. Mud stream from the outlet of mud pump flows through a by-pass valve into the

motor. This steam produces pressure loss at both inlet and outlet of the pump, to push the rotor

into rotating, and to transmit the torque and speed onto the bit.

Model YTLX Hydraulic Adjustable Stabilizer

Specifications

Model YTLX hydraulic adjustable stabilizer is a new kind of adjustable

stabilizer for well drilling. The adjustable stabilizer pushes out its piston by the

drilling pressure to adjust its diameter. When drilling or lifting the drilling tools, its

piston will retract automatically to prevent blockage or jamming phenomenon.

Because of simple structure, good abrasion resistance, and wider adjustable

diameter range, the stabilizer can be used to expand the hole, especially suitable for

directional drilling and horizontal drilling.

Model NCQ Torque Impactor

Specifications

Model NCQ torque impactor can convert the fluid energy of the drilling fluid into the high-

frequency circumferential mechanical shock energy, and directly pass the energy to PDC bit, so

that the drill bit can cut the formation frequently and continuously without waiting for enough

energy of the drilling rod torque, while the torque passed by the whole drill rod is stable and

balanced, the torque can be completely used to cut the formation of no waste, which can reach

the purpose of improving the mechanical drilling speed.

Model ZTX highly-efficient vibration resistance reduction tail pipe running tool

Specifications

Model ZTX highly-efficient vibration resistance reduction tail pipe running tool is connected

to the drill string, so that the drill string at upper end of the tool can individually rotate independent

of the drill string at the lower end. When any blockage or obstruction occurs to the drill string at the

lower end, the tail pipe can eliminate the resistance and friction which is caused by the rotation of

the drill string at the upper end, and reduce the helical distortion of the drill string. A "pressure

activated clutch" is set inside the tool to form some differential pressure to hold the pressure in the

central tube, and the shear pins inside the tool make the upper part and lower part to reform

recombination and synchronous rotation, transferring the torque of the upper drill string to the

drill string at the lower end.

Model LM-TX Rotating Spear

For LM-TX rotating spear, a bearing system is installed between the

mandrel and spear rod. During the cutting operation, the mandrel joint

drives the tubular column at the lower end of the mandrel to rotate

together through the connecting screw threads, which greatly reduces the

friction resistance in the process of rotation and improves the cutting

efficiency.

Junk Mill Type MXP

Specifications

Junk Mill Type MXP can be divided into three kinds: flat-bottom (or

concave-bottom) milling shoe, guide milling shoe and cone milling shoe,

according to its structure and shape. At the milling surface, the carbide

particles are built up by welding, which plays a part of self-milling. It is

used to mill the fallen substances, such as tooth wheel, slipdog, fittings for

deep-well pump, etc. with the advantages of anti impact and longer

service life.
