DRILLING JAR

Specifications

DRILLING JAR

LHBZ mechanical  is a full mechanical drilling jar, it also can be used as fishing tool. It generates upward jarring as well as downward jarring which can solve tight pull or sticking troubles during drilling. It is the first optional drilling jar for vertical well, deep well, directional well and complicated well operations

Luhai drilling motor is a positive displacement motor. High pressure drilling fluid fl ows into the , thereby enabling the hydraulic energy to be converted into mechanical energy, at the same time, the rotor drives the shaft and bit to rotate to achieve the purpose of drilling.

Luhai produces LZ73, LZ89, LZ95, LZ102, LZ120, LZ127, LZ146, LZ165, LZ172, LZ185, LZ197, LZ203, LZ216, LZ244, LZ286 and other types of drilling motors. They are for drilling diameter of 88.9-660mm. Luhai also design and develop drilling motors with special sizes, different structural features and operating characteristics in accordance with the user's requirements, thus forming different varieties. At present, in addition to ordinary straight drilling motors, Luhai can also provide the following types of drilling motors:

1. Bent drilling motors: The bent angle on the universal shaft can meet different kickoff requirement, there are single-bent and double-bent available.

2.Bent angle adjustable drilling motors: The bent angle of the drilling motors can be adjusted on well surface which enhance the extension of kicking off.

3.Extension drilling motors: On the basis of the ordinary drilling motor, improve motor torque to make the bit drilling quickly by increasing motor stage.

4.Hollow drilling motors: To meet the needs of high fl ow rate solids carrying in drilling, hollow rotors with carbide nozzles of different sizes are adopted, which can increase the input fl ow rate and the horsepower of drill bit..

5.Drilling motors with high kick-off rate: Unique structural design, shorter body, bent point closer to the drill bit, and kick-off rate of up to >1°/m.

6.Saturated saltwater mud-resistant drilling motors: To maintain long time operation of drilling motors in saturated saltwater mud, special rotor coating is adopted to provide better corrosion and wear resistance.

7.High-temperature drilling motors: In order to improve the high temperature resistance of the stator rubber of the drilling motors, to meet the drilling requirements in high geothermal gradient region and deep and ultra-deep well drilling requirements, high-temperature resistant rubber is adopted to increase the temperature resistance of motor above 150℃.

8.Sealed driving shaft drilling motors: The ordinary mud lubricated driving shaft is replaced with oil lubricated seal driving shaft, which improves the working conditions of the thrust and radial bearings, thus extending the service life of the drilling motors.
