Screw Pump

Screw pump is an ideal pump for feeding to decanter centrifuge without shearing or agitating the drilling mud. The main parts are screw shaft (rotor) and screw shaft bushing (stator). Because of the special geometry shape of the two parts, they form pressurize capacity separately. The fluids flow along with the shaft, inner flow speed is slow, capacity remains, pressure is steady, so it will not generate vortex and agitating.

Key Features:

●Compared with the centrifugal pump, screw pump does not need to install the valve, the flow is stable linear flow.

●Compared with the pneumatic diaphragm pump, screw pump can transport a variety of mixed impurities containing gas/ solid particles/ fibers of the media, as well as a variety of corrosive substances.

●Compared with the gear pump, screw pump can transport high viscosity material.

●Compared with the plunger pump, diaphragm pump and gear pump, screw pump can be used for chemical filling and metering.

Centrifugal pump

Centrifugal pump is the ideal equipment to provide impetus for Desander、Desilter and Jet Mud Mixer. It can also be used as Charge Pump auxiliary perfusion for mud pump and Trip Pump for drilling well head. Centrifugal pump is also called sand pump.We considered completely the set equipment can work in excellent condition in the process of designing parameters).Most parts can be exchanged , with convenient operation and maintenance、less seal leakage、reliability、long life and other advantages.

Vacuum Degasser

Vacuum Degasser is also called mud/Gas separator. Mud/gas separators (Degasser) is  the first units of solids control equipment arranged to treat drilling mud. As such, they process all of the drilling mud from the flow line before the mud reaches the primary shale shakers. The units have no moving parts and rely on the density difference between the gas and the mud for removal. The process is simple, yet very effective for well drilling fluids processing system.

Vaccum Degasser  is used to remove the small entrained gas bubbles left in the mud by the mud/gas separator. These units are positioned downstream from mud/gas separators, gumbo removal equipments (if utilized), shale shakers and mud conditioners (if utilized), while hydrocyclone desander and Decanting centrifuges follow in the arrangement.

Key Features:

●Self-priming device enables it to pump drilling fluids without centrifugal pump

Drilling mud cleaner

Drilling mud cleaner is also called Desander and Desilter assembly,which is the combination of desander,desilter and an underflow screen.Namely,mud cleaners consists of a two-stage separation process using a combination of hydrocyclones mounted over a shale shaker to operate as a single unit. Designed to handle the entire circulating volume, Drilling cuttings cleaners are effective on both weighted and unweighted drilling-fluid systems in removing and drying solids while retaining the expensive liquid. The hydrocyclones(desanders and desilters) make the primary separation with underflow directed onto the shaker’s vibrating screen. Used correctly, the drilling mud cleaner lower both drilling-fluid and disposal costs.

In oilfield solids control,drilling mud cleaners are very efficient for oil gas well drilling  mud purification system.Mud Cleaners are one of the important equipments for solids liqiud separation system.

Drill bits

LUHAI PDC bits are designed professionally for different formations to meet with various drilling applications. ROP and durability improvements are ensured by advanced cutting structure layouts, high performance PDC cutters and superior hydraulic design.

LUHAI core bit uses tungsten carbide matrix with a steel skeleton in it. The bits adopt parabolic, double cone, tapered step crown profile, and diamond inner and outer gauge. We can provide possible quick ROP, high core recovery, low cost, excellent durability core bits in various formations under all drilling conditions combined with other types of core tools.

LUHAI rock bit is the most popular one in use. When working, the cogging touch the bottom alternately, breaking torque and the contact area both are small, thus the unit pressure is high, so it can penetrate into the layer easily, The length of the blades is longer, which can
reduce the abrasion. The rock bit can adapt to a variety of formations from soft to hard.

STABILIZER

LUHAI provides integral straight blade stabilizer, integral spiral blade stabilizer, replaceable sleeve stabilizer, non-rotary stabilizer, diameter changeable stabilizer etc. There are Five kinds of hard facing(HF1000,HF2000,HF3000,HF4000,HF5000). All above products are manufactured according to API Spec 7 standard.

The working surface has five kinds of hard facing:

HF1000

Crushed tungsten carbide held in a nickel bronze matrix. The 3mm grain size ensures greater concentration of carbide which is ideal for drilling soft formation.

HF2000

Trapezoidal tungsten carbide inserts held in a sintered carbide nickel bronze matrix. This will give a great depth of carbide coverage-ideal for high deviation drilling in abrasive formations.

HF3000

Tungsten carbide inserts sets in a powder spray deposit ideal for abrasive formations.97% bonding guaranteed,certified by ultrasonic reports. This kind is recommended for non-magnetic stabilizer.

HF4000

Tungsten carbide inserts (button type), The inserts have been developed to allow cold insertion and maintain close fit. A great concentration of inserts on the bottom third of the blade and leading edge will increase surface contact to reduce wear in highly abrasive formations.
