Downhole Motor Configuration Option UnifromThickness:Reasonable to change the shape of stator housing, the statorelastomer layer of Unifrom Thickness downhole motor is thin and even. Thecharacteristics of the downhole motor are short length, high power, highpressure drop, low rotate speed, high cooling efficiency, even thermalexpansion, more widely used, more optimized structure and the lighter mass.Especially, the characteristics can prolong downhole motor's life and improvedrilling efficiency in the ultra-deep well, directional well and hightemperature well.
Resistance High-temperature And Oil BasedMud:The downhole motor is suitable for high-temperature, high oilbase mud system. In the conditions of less than 180°C and high oil, speciallyformulated stator elastomer owns high retention rates of strong force strength,tear strength and other properties. The oil-resistant elastomer with reasonablemagnitude of interference has better using effect in the high-temperature, highoil base mud.
Corrosion-resistance:Aftercorrosion spraying to form special coating, the rotor is better corrosion,erosion and abrasion-resistant. And downhole motor is suitable for long time inthe corrosive fluid.
Air Drilling:Airdrilling can protect reservoir well, improve rate of penetration, significantlyshorten drilling period, take precaution against mud loss and boreholecollapse, now is gradually widely used. Air drilling downhole motor is drivenby gas, foam and other compressible fluids, provide power for the downhole anddrives bit to penetrate rock. Air drilling downhole motor has higher technicalrequirements of the assembly structure, linear design of the motor stator andoperation specification.
