Product Description:
Working principle of screw drilling tools:
Screw drilling tools are a type of volumetric downhole power
drilling tools that use drilling fluid as power and convert liquid
pressure energy into mechanical energy. When the mud pumped out by
the mud pump flows through the bypass valve into the motor, a
certain pressure difference is formed at the inlet and outlet of
the motor, and the hydraulic energy is converted into mechanical
energy, and the speed and torque are transmitted to the drill bit
through the universal shaft and the transmission shaft, thereby
realizing the drilling operation.
Our company Huichi petro can supply screw drilling tools of
specifications such as LZ73, LZ95, LZ102, LZ120, LZ146, LZ165,
LZ172, LZ185, LZ7, LZ203, LZ216, LZ244, LZ286, etc., which are
suitable for drilling operations with a diameter range of
88.9-660MM. Various downhole motor assemblies for well size 1
7/8"~26" with 24 main dimension specifications (which are
identified by outer diameter of stator) : 1-11/16", 2-1/8", 2-3/8",
2-7/8", 3-1/8", 3-1/2", 3-3/4", 4", 4-1/8", 4-3/4", 5", 5-1/4",
5-7/8", 6-1/4", 6-1/2", 6-3/4", 7-1/4", 7-3/4", 8", 8-1/4", 8-1/2",
9", 9-5/8", 11-1/4". At the same time, we can also design screw
drills with special specifications and sizes according to user
needs, develop screw drills with different structural features and
working characteristics, and form a multifunctional series of
different drilling tools.
At present, in addition to the more common straight screw drills.
The following forms of screw drills can also be provided:
1. Bent screw drills: On the universal housing of the screw drill,
a structural bend is added to meet the needs of different
curvatures. It is divided into single-bend housing and double-bend
housing.
2. Adjustable angle screw drills: In order to improve the
requirements of bent screw drills for different deflection rates,
the bending angle of the screw drill can be adjusted on the well as
needed.
3. Extended screw drills: On the basis of ordinary screw drills,
the number of motor stages is increased to increase the torque of
the screw drill to achieve the effect of rapid rock breaking of the
drill bit.
4. Hollow screw drills: In order to meet the needs of large-volume
cuttings during drilling, a hollow rotor with nozzles of different
sizes is used to increase the input flow and increase the drill bit
water drive.
5. High-deflection screw drills: Unique structural design, the
length of the whole machine is shorter and the curvature is closer
to the drill bit.
Composition of screw drilling tools:
The composition of screw drilling tools is mainly composed of four
parts: bypass valve, hydraulic motor, universal shaft and
transmission shaft.
Product Features:
1. According to user needs, we can design screw drills with special
specifications and sizes, develop screw drills with different
structural features and working characteristics, and form a
multifunctional series of different drills;
2.Drilling Motor Increased rate of penetration;
3.Better hole deviation control;
4.Reduction in drill string failure rate;
