Drilling Tool Luhai drilling motor is a positive displacement motor. High pressure drilling fluid fl ows into the drilling motors, 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.

Float shoes contain a backpressure valve that prevents fluids from entering the casing while the pipe is lowered into the hole and prevents cement from flowing back into the casing after placement, while enabling circulation down through the casing. Float collars are placed one to three joints above the guide shoe or float shoe. They provide a seat for the cement plugs, the bottom plug pumped ahead of the cement and the top plug behind the full volume of slurry. Once seated, the top plug shuts off fluid flow and prevents over-displacement of the cement. The space between the float shoe and the float collar provides a containment area to entrap the likely-contaminated fluids from the wiping action of the top cementing plug, securing the contaminated fluid away from the shoe where a strong cement bond is of primary importance. Float collars include a backpressure valve and serve basically the same function as the float shoe. Features: The Aluminum Alloys used in this product are PDC Drillable. Available in 5 1/2â?� to 20â?� sizes. Customized sizes are also available. Applications:In all applications ranging from close tolerance liners to full casing strings. Standard float shoe is provided with round cement nose to deflect offledges or obstructions. Customizable options including nose types, ports/jets, and ball deflector. Can be supplied either in Single Valve or in Double valve.
Sucker rods are manufactured according to API 11B Specifications. Currently, we market 3 types of API sucker rods Grade D Alloy and Grade D Special which are formulated from different alloysï¼?AISI 4130 (Grade D), AISI 4142 (Grade D) and AISI 4720 (Grade KD). Manufacturing Process: 1. Rod Bar The incoming rod bars are inspected for any damage, fault and discontinuities.Before arranging the rod bars for production process, carry out chemical composition testing, dimensional inspection & surface quality inspection. High quality standard is maintained at various stage inspections. 2.Manufacturing Rod bars are manufactured from hot rolled alloy steel. Rod bars are machine straightened and cold drawn to the required size. The rod bar ends are hot forged according to API designed sizes. The rods are then heat treated over the full length.As per requirement of mechanical properties, the rods are normalized and tempered to the specified level or quenched and tempered to the required hardness and strength. Care is taken to achieve metallographic structure with no residual stresses in the rod.A sample specimen is cut from the heat treated material and is tested for ultimate tensile strength, yield strength and elongation. The rod is then again checked for straightness. The forged ends are properly aligned with its body. Rods are cleaned by shot-blasting to remove any scale and oxidation. The forged ends are machined on C.N.C. Lathe machines as per API dimensions and checked with API approved gauges.
