The PDC bit's compact cutting structure just utilizes the mechanical property of rock, and uses the efficient shearing way to break the rock, thereby achieving the purpose of fast drilling. When PDC bit in a formation with soft to intermediate hardness, the compact cutting teeth overcome the formation stress enter the formation and slide forward under the effect of WOB and torque, and the rock is broken along its shear direction under the action of cutting and plastic flow is produced. The cuttings produced by cutting are in large pieces, which are then brought by the mud jetting out from nozzle to the annulus between the drill bit and the borehole wall, are transported out of the well.
 

GLB single screw pump is a new type of mechanical oil extraction equipment, which is suitable for both low viscosity crude oil production and high viscosity oil, high condensation point oil, high wax oil, high sand oil and high gas oil extraction. It is an effective supplement to the conventional pumping pump with the features of low investment, high oil extraction efficiency, low energy consumption, convenient installation, operation and maintenance, and it will become a commonly used mechanical equipment in oil production in the future.

Weifang Shengde TC bearings, high strength, long life inlaid carbide radial bearings is our company's proprietary technology, is currently the earliest domestic production of radial bearings company. Radial bearings inside and outside the surface of the regular arrangement of cemented carbide blocks and special composition of solder, cemented carbide filler, through the special sintering treatment, so that it and the base parts fused into one. Its friction vice has the outstanding features of corrosion resistance, impact resistance, large load bearing and long service life, and its appearance quality and technical indexes have exceeded those of similar foreign products.

Reaming is an important procedure in horizontal directional drilling, reaming is a necessary tool for reaming, and rock reamer must be used in rock stratum, at present, Rock Reamers at home and abroad are divided into two categories according to their structural forms: HOB type and cone type. Hob type is only suitable for medium-hard rock, although the cone type is high in cost, it is safe and suitable for all kinds of rocks, according to the performance of this unit, a complete set of cone-shaped rock reamer is developed, which is matched with the machine.

Downhole Motor is a kind of volumetric downhole motor, which works on the principle of converting the high-pressure liquid energy of mud into the mechanical energy of rotating drill bit. It is widely used in oilfield and mining for directional wells, horizontal wells, clumped wells, straight wells, etc. for drilling, slanting, twisting azimuth, coring, reaming, window side drilling and workover operations, and can be used for special operations such as composite drilling and traversing.

Hydraulic disassembling and assembling frame is a special equipment for disassembling, assembling and repairing all kinds of drilling tools for petroleum and geology, which is developed by our company on the basis of absorbing the advanced technology of similar equipments at home and abroad, and combining with the status quo and characteristics of our use.
