Downhole motor is a kind of downhole dynamic drilling tool upon the power of drilling mud. Mud stream from the outlet of mud pump flows through a by-pass valve into the motor. This stream produces pressure loss at both inlet and outlet of the pump, to push the rotor into rotating, and to transmit the torque and speed onto the bit. The downhole motor property mainly depends upon its property parameters.
ADVANTAGES OF DOWNHOLE MOTOR
Increased rate of penetration.
Better hole deviation control.
Reduction in drill string failure rate.
Reduction in wear and tear of the swivel, Kelly, and rotary drives.
Reduction in fuel cost, since compared to rotary drilling, less energy is required to power a downhole motor.

Benefit:Improved bit durability and directional responsiveness
Advantage:Higher nozzle counts and/or fixed ports to best serve cleaning,cooling and cuttings evacuation requirements with available hydraulic flows.Allow for higher flow rates with minimal increase in pump pressure.
2. Detailed introduction to Bit breaker
1) Bit breaker is mainly used to screw on or off a rock bit to the bottom of drill string.
2) It can also prevent the rock bit from dropping into well hole.
3) The price of it is cheap and the use of it is safety and reliable.
4) It is easy to operate. First, the bit breaker is placed on well hole and then put the rock bit onto it. Turn it to screw on or off the bit by turnplate.
1. About the Manual
The Lake Drilling MOTOR is a powerful and reliable positive displacement motor. The motor generates an optimum balance of rotational speed and high torque to drive a variety of drill bits at speeds that maximize tool life and performance. LAKE MOTORS offers a choice of flow rates, speeds, and torques to match a wide range of operational parameters. LAKE MOTORS are used in applications such as straight hole drilling, directional (steerable) drilling, horizontal drilling, hole opening, and re-entry(work over).

Usage It is one kind of positive displacement downhole motor, with working principle is to convert the high pressure fluid power of mud into mechanical energy for bit rotation. It is widely used in oil field and mine directional well and horizontal well, cluster Wells and vertical Wells, drilling, deflecting, adjusting azimuth, coring, reaming, side tracking and workover treatment, and also applied in some special operations as compound drilling and traversing, etc.
A Variof Types &ety the Capabilities In accordance with the actual drilling needs, we push out high, midiem and low speed downhole motors, of a variety of types with different functional configuration and application for all working conditions.
1.The Quick-operating Thread Protector is a manually-operated device for protecting external pin-end threads on casing. It is simple, tough and secure, The fast and easy operation of Quick-operating Thread Protectors saves casing screw time, saves rig time and saves your money.
2.The Quick-operating Thread Protector consists of a high strength spring-steel band molted inside strong, abrasion-resistant rubber. An adjustable cam-type latch assembly is incorporated for manual locking and unlocking of the protector. To operate the Quick-operating Thread Protector, place the protector on the pin-end threads of pipe, push the handle firmly toward the center of the pipe and the locking action securely closes it in place. Pull the handle out to release.
A mud cleaner is a combination of desanders and/or desilters mounted over a shaker with a fine mesh screen. A mud is fed to the inlet of the hydrocyclone (desander and/or desilter) to separate particles and the underflow passes to the fine screen mesh where in particles larger than barite are discarded and thrown away. In most drilling operations, a mud cleaner is installed in its mud systems. It is usually located in a mud tank in the same location as with the desilters.

We can produce all types of drilling rods such as HDD drilling rods, oil drilling rods, geological drilling rods, anchoring drilling rods and other special drilling rods, and trenchless special drilling tools such as pilot guide bits, swivels, ream bits, reducer unions,pneumatic pipe-rammer,hydraulic power break out tong for drill pipe.
We supply slick drill collars, spiral drill collars and non-magnetic drill collars; their sizes are from 3-1/8 to 11 inches. Besides the drill collars in the table below, we can supply other drill collars at customers' request.
Materials:
Drill collars are manufactured from AISI 4145H modified steel, and are supplied in the "as rolled" surface finish condition. Alternative surface finishes are available.
Trepanning and Heat Treatment:
Drill collars are trepanned and drifted to API Spec 7-1. Full-length heat-treatment processes ensure that mechanical properties meet or exceed API Spec 7-1 requirements. A hardness range of 285-341, Brinell hardness and Charpy "V" notch minimum impact strength of 40 ft-lb at 70 F are guaranteed one inch below the surface.
Traceability:
Drill collar material and process traceability are maintained from receipt of the mill's certified raw material to completion of manufacturing. Serial numbers are die stamped on bar bodies.
Rigid Inspection Procedures:
We inspect all our drill collars to ensure compliance with API SPEC 7-1 standards. These inspections include visual dimensional checks as well as ultrasonic inspections over the entire body of the drill collar.
Cold Rolling:
Drill collar thread roots, as well as elevator recess upper radius, are cold-rolled. Cold rolling creates a compressive recess upper radius stress condition that increases fatigue life by minimizing crack initiation.
Phosphate-coated or Copper Plating:
All connections are phosphate-coated or copper plated to improve resistance to corrosion.
Slip Groove, Elevator Groove and Size:
Lake offers optional slip and elevator recesses to improve handling efficiency and safety. Unless otherwise specified, slip and elevator recesses are machined in compliance with API spec 7-1 guidelines.
Thread Protectors:
Our company offers steel, cast steel and plastic steel thread protectors for its drill stem products.
