Downhole motor

Down-hole motor is a positive-displacement motor. It converts high fluid energy into mechanical power of bit rotation. Down-hole motor is commonly utilized for drilling, deflecting, azimuth control, coring, reaming, facet monitoring drilling and workover for horizontal well, cluster wells and straight well of oilfields and coal mines. In addition, it is suited for complex drilling

CZPTtek gives numerous dimensions of down-hole motors for hole dimensions from 1 7/eight” to 26″. Common dimensions are 1 11/sixteen”, 2 7/8″, 3 1/8″, 3 1/2″, 3 3/4″, 4″, 4 3/four”, five”, 5 5/sixteen”,five 7/eight”, 6 1/4″, 6 1/two”, 6 3/4″, 7 1/4″, 7 3/four”, 8″,eight 1/4″, 8 1/two”, nine”, 9 5/8″ and eleven one/four”.

CZPTtek is able to offer down-gap motors of specific dimension, higher-speed, medium-pace and low-pace, in accordance to customer’s needs

Downhole Motor Doing work Theory

Downhole motor is a kind of downhole dynamic drilling device upon the power of drilling mud. Mud stream from the outlet of mud pump flows by means of a by-go valve into the motor. This stream creates pressure decline at equally inlet and outlet of the pump, to push the rotor into rotating, and to transmit the torque and speed onto the little bit. The downhole motor property mainly relies upon on its residence parameters.



 Constitution of Downhole Motor 


Downhole motor is composed of 5 assemblies of bearing, electricity segment, coupling, anti-fall and bypass valve.





Attributes of Large Flow Rate Down-gap Motor

Functions of Uniform Wall Thickness Down- gap Motor

The adoption of hollow rotor cooperating with tough alloy jet nozzle of distinct dimensions increases enter stream fee and proppant carrying capability.

This down-gap motor can effectively fix the difficulty of uneven thickness of motor’s rubber. Its attributes are as follows: high stress enduring for single quality, large output power, vast range of high performance, and so on.

Characteristics of Bent Angle Adjustable Down-hole Motor

Functions of Near Bit Down-hole Motor

The bend angle of down-hole motor can be adjusted on wellhead. Stabilizers of various shapes and dimensions can be changed according to various specifications.

Measure stage of measuring instrument is set up in downhole motor, which is nearer to drilling bit. Drill track is much more accurate and trustworthy.

Features of Common Down-gap Motor

Features of Saturated Saltwater Mud Resistant Down-gap Motor

Regular energy section the transmission shaft is lubricated by drilling fluid accessible in vertical, single-bend and double-bend sorts maximum functioning temperature is 120°C.

The particular coating layer of rotor has more robust potential of corrosion and use resistance, enabling down-hole motors to work a long time in saturated saltwater mud.

Features of Oil-sealed Transmission Shaft Down-hole Motor

Features of Higher Temperature Resistant Down-hole Motor

The functioning environment of thrust bearing and radial bearing is improved, and the operating time of down-hole motor in the course of one one trip is elevated.

The stator is equipped with outstanding quality higher temperature resistant rubber, which enables down-gap motor to perform stably for a long time underneath the hole exactly where temperature even reaches 150°C and180°C.

Characteristics of Prolonged Down-hole Motor

Functions of High Deflection Down-gap Motor

The torque is improved by thirty% to sixty% in contrast with regular down-hole motors the transmission shaft is lubricated by drilling fluid accessible in vertical, single- bend and double-bend types optimum functioning temperature: 120°C.

The special construction can make the motor shorter, the bending position nearer to drill bit, and higher construct-up charge.
