1. 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.
2. CONSTITUTION
Downhole motors differ in size and performance characteristics, but they share the same basic components as follows (Fig.1) :
Crossover Sub Safety Catch Sub Power Section Coupling Assembly Bearing Assembly
The sucker rod, an essential part in the rod production system, is used to connect the pumping unit on the ground and the oil well pump down in the well.Products comply with Specifications of Sucker Rods (API Spec 11B) and other related standards, and have acquired the authorization to use Official API Monogram.The company produces K, C, D or HL sucker rods with various specifications complying APIâ??s requirements.
Technical Performance & Characteristics
1,Advanced online fault detection, hardening, continuous overall tempering and ball blast techniques are incorporated so that mechanical strength and overall performance are enhanced. 2,Threads are processed on special numeral control lathes avoiding any rotation of the rod and then subject to roll forming so as to ensure high precision, reliable performance and extended service life.
1.Description:
The mechanical-hydraulic drilling jar is a jarring and stuck releasing tool. It integrates the up jar and down jar and can release the stuck accident occurring during drilling operation. The drilling jar is an ideal tool for directional well and deep well drilling.
Operating principle
1.Operating principle of up jar
Lifting drilling tool, slip assembly which bear the acting of dish reed elastic force and slip locking force compels latch mechanism of slip clasp slip mandrel. While slip mandrel up run with mandrel to overcome slip locking force and damping action between hydraulic valve assembly and spindle extension, jar
Make drill stem accumulate energy, delay time. When mandrel up run to the state of release constraint, elastic potential energy accumulated in drill stem will convert to upward kinetic energy, generate up jar. If need sequence up jar, you need fed off drilling tool till relock latch mechanism, reduplication above process,
Generate sequence up jar.
2.Operating principle of down jar
The loosen load of down jar lock can be transfer as per in demand .There are a certain ratio between up locking force and down locking force , and the ratio is adjustable. If down jar, fed off drilling tool until pressure reach to down locking force, jar should generate down jar force. If need to repeat jar, lifting drilling tool to anew securing position repeat above process.

Best quality pneumatic soft seal butterfly valve used in oil and gas
Product description
Butterfly valve is closed a disc, around the axis of rotation to achive a valve open and close, in the tube on the main cuttring and throttling. Opening and closing is a disc-shiped buttefly plate, the body is around its own axis rotation turn, so as to achieve the aim of opening and closing or adjust. Buttefly valve fully open to the barrier is usually less than 90â°c, butterfly valve and the adjusment rod itself-locking ability, for the sake of the butterfly plate positioning, to add worm gear reducer on the valve stem, the use of worm gear reducer, can not only make the butterfly plate with self-locking ability. Make the butterfly plate to stop at any position, can also improve the operating performance of the valve.
