Roller cone bits

Three cone bit is an important tool for oil drilling, its work performance will directly affect the quality of drilling, drilling efficiency and drilling costs. Three cone bit design is based on practical experience, combined with the test method, repeated design and calculation, and thus low design accuracy, long cycle, it is difficult to improve the design quality, and each calculation can only design a drill, low efficiency. Featured products SKV Series Six-Point Position Stabilization Motor Bit Cutting Structure The durability of premium tungsten carbide inserts is improved with new formulas and new techniques Gauge Structure Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone,tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life. Bearing Structure High precision journal bearing with two thrust faces,Balls lock the cone,Hardfaced head bearing surface.Cone

Super Fishing Jar

SCJ type super fishing jar is a fishing tool that provides larger jarriing force when compared with others of the same specifications. This jar's structure is compact, performance is reliable and is easy to adjust and operate under different drilling conditions. The SCJ type super jar is a new type of top jarring tool used in oilfield, geological exploration and drilling operation. Working principle of  Super Fishing Jar SCJ type super fishing jar achieves the top jarring action by means of hydraulic mechanism. When the drill tool attached directly above the super fishing jar is raised, there is sufficient time for the drill tool to store elastic energy due to the damping action between the tapered piston and the sealing body. When the taper piston slowly moves to the release bore, the drill tool suddenly contracts and produces an upward dynamic load by the instant unloading of the pressurized hydraulic oil. A reliable impact working surface is designed in the product structure

Hydraulic-mechanical Drilling Jar

Hydraulic-mechanical drilling Jar is a double acting jar, Hydraulic-mechanical drilling Jaris designed to deliver hydraulic delay when jarring in the up direction, and mechanical release when jarring in the down direction. It provides excellent functional stability and strong jarring forces in both jarring direction. It is used to free stuck drill string components and is recommended for directional/ deep wells drilling application. Working principle of Hydraulic Mechanical Drilling Jar Up Jarring Lower the drill stem to ensure that drilling jar is closed completely (in locking position).Up jarring is achieved by slowly increasing the lifting force on the drill steam,until there is sufficient pull force to overcome the spring resistance and initial hydraulic time delay. During the time delay, the overpull at surface can be adjusted to vary the desired impact force.When the mandrel reaches the trigger position, there is a sudden release in resistance, the elastic potential energ

Hydraulic Drilling Jar

The SQYZ type drilling jar is a kind of hydraulic jar that can be employed to release the drilling tools that are stuck . With this one-piece double acting hydraulic jar, a powerful force is available to the operator and ensure that normal drilling operations can be resumed as soon as possible. When operating the SQYZ type hydraulic jar, the operator can make adjustments to the jarring force and direction on the ground without the need to adjust torque. The SQYZ jar is reliable and can be operated with ease. It can applied widely in drilling, coring, fishing and cementing operations. Working principles of Hydraulic Drilling Jar ●  Upward jarring Lighting the drill stem gives the hydraulic jar an upward force, moving the upper hydraulic mechanism along with it. This generates an increased pressure in the working fluid. Thus, when the jar reaches a predetermined stroke, the fluid pressure is released, creating an upward jarring force, releasing the stuck drill stem . ●  Downwa
