Drill slips can accommodate drill pipe from 2 3/8 to 5 1/2inch (60.3139.7mm) O.D.. They are classified as type short (SDS), medieum (SDML) and extra long (SDXL) according to gripping length. SDS slips are designed for shallow hole drilling, SDMLslips are the perfect choice for all medium depth drilling, SDXL slips are designed for deep drilling.

ZQ drill pipe power tong is an ideal wellhead tool for oil drilling, widely applied in

Slip type casing elevators/spiders are tools for handing casing from 4? 14inch O.D.

make-up and breaking-out for well drilling and repairing on offshore and land. Openthroat design of the ZQ series with high mobility allows escaping from drilling pipe freely. The tong is a combination of spinning tong and torque tong. It substitutes cathead, suspension tong and spinning rope in making-up and breaking-out.

Structure features and applications of the bit The bit is optimally designed with medium contour which is suitable for soft to medium soft stratum. Cutting structure is force balanced, blade is asymmetrically designed, spiral blade and spiral gage are designed so that the load on drill bit is balanced, get better stability. Multiple types of high performance PDC cutters are strategically arranged on the bit for improved service life of the bit. Shock absorbers are designed to make the bit capable of drilling through formations with hard stringers. Erosion on bit surface is effectively prevented by utilizing hardfacing material of highly erosion resistant and applying advanced base metal enhancement technology. Ports on bit are also optimally designed to prevent erosion of water courses inside the bit.

The ZJS type jar intensifier is a down hole fishing jar designed to increase jarring energy to

The DJ Type Surface Bumper Jar is an effective tool for resolving the problem of stuck drill

up jar .Therefore ,it must be run in conjunction with CSJ type super jar or YSJ type hydraulic

tool in down hole.It is connected with the surface section of drill string, the device to

adjust the tonnage shall protrude from the rotary disc face, the violent down jarring to the

free jarring stroke .With a special function ,the intensifier is essentially a fluid spring which

stuck catch can be clearly seen when the surface jar makes jarring operation. The jarring

not only can accelerate the up jarring action but also make the jarring action directly to

strength for the tool can be easily adjusted and it is a easy operated, unique designed tool

which can make continuous down jarring .The surface jar, which not only can bear heavy load and strong torque but also owns a good sealing property and can withstand the mud

SJ Type Shock Absorber Shock Absorber Type SJ should be connected with the drilling string close to the bit. It can reduce or absorb both longitudinal and circumferential vibration of the drilling string in drilling operations. It can achieve the optimum combination of drill pressure and drill speed, reduce the drilling cost and promote the drilling efficiency.
