Downhole Tools For Oilfield

1. About the Manual The Lake Drilling MOTOR is a powerful and reliable positive displacement motor. The motor generates an optimum balance of rotational speed and high torque to drive a variety of drill bits at speeds that maximize tool life and performance. LAKE MOTORS offers a choice of flow rates, speeds, and torques to match a wide range of operational parameters. LAKE MOTORS are used in applications such as straight hole drilling, directional (steerable) drilling, horizontal drilling, hole opening, and re-entry(work over). 2. 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. 3. 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 -

Cementing Head Type The cementing head is special tool for pumping slurry and releasing plug and can be connected with casing. Features: * Main parts are made from AISI4145H alloy steel. * Quick-latch adapter is designed to offer easier, faster and safer makeup for two-stage cementing. * It is manufactured utilizing API grade steels with API threads. * Positive lever indicates plug releasing. * Balance pipe is developed.

As a manufacturer and a supplier we produce cementing tools since 1997, and now we have almost 400 workers, the products cover cementing head/plug, stage collar, float equipment, centralizer and so on. Please contact me if you have need, and my email is

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.
