The Most Important Oilfield Mud Equipment- shale shaker

Oilfield drilling is a complex process involving multiple pieces of equipment to ensure proper extraction, cleaning, and safety. While the variety of oilfield equipment used can at first be overwhelming, we’ve listed out the most important pieces to become familiar with. It plays an important role in reducing costs, accidents, and environmental impact.

shale shaker 1

The most important part of the solids control/separation system on a rig, shale shakers separate the “cuttings” (large solids) from the “mud” (drilling fluids). After the mud is separated, it is used to keep the drill bit cool.

Ideally, these fluids can be reused more than once. This separation before the disposal of cuttings helps reduce drilling costs and environmental impact. Proper controlling of drilling fluids is correlated directly to the efficiency of all other downstream controlling equipment later in the process.

In order to supply the excellent shale shaker with high screening accuracy, low-energy and no dust pollution, DC Machinery controls quality strictly in each procedure.

Proper screen is important for shale shaker using

Shale shakers are devices that remove drill cuttings from the drilling fluid that is used for boring holes into the earth. Controlling the solids in drilling fluid is an important component of the cost of drilling, so research into improved shale shaker design is ongoing.

Shale shakers typically consist of large, flat sheets of wire mesh screens or sieves of various mesh sizes that shake or vibrate the drill cuttings, commonly shale, across and off of the screens as the drilling fluid (mud) flows through them and back into the drilling fluid system.

This separates the solid drill cuttings from the fluid so that it can be recirculated back down the wellbore. In oilfield industry, linear motion shale shakers are widely used.

Screen panels play a major role by removing particles larger than the mesh size. Screen selection is critical since shaking is the primary stage in the removal of solids.

Improper screen selection can lead to de-blinding, loss of drilling fluids, premature pump part failures, overloading of other solids removal equipment within the mud systems, decreased service life , reduced flow rate capacity, and serious problems in the wellbore.

The care and maintenance of Shale Shaker Excitation Motor

The care and maintenance of Shale Shaker Excitation Motor can increase shale shaker work efficiency, extend service life of shale shaker and reduce the operation cost.

1 The dust on the casing should be cleaned periodically.

2 Before operation the fix bolts of the motor should be checked to see if they are loosened. If so, they should be fixed tightly before use.

3 Check to see if the service cable is rubbed, buried or squeezed.

4 A good lubrication of the motors should be ensured during their operation.

An appropriate amount of high temperature lubricating grease has already be injected into the bearing before its assemblage, with working temperature between -40~200°C.

Not more than 25.8g lubricating grease should be injected into each bearing for every 2000 hours.

Usually the temperature of the bearing will rise for one or two days after lubrication. The lubricating holes should be sealed to prevent dust from entering into the bearing and damaging it.

5 The insulating test should be done to the coil of the motor after a long period of halting. It will not be operating until the resistance is less than 0.5 MSZ when testing with 500V megameter.

Attention:

The power supply should be cut off immediately when the motor is found not running with power supply connected to avoid damage the motor.

Observe the motor to see whether there are anything abnormal happened, such as intermittent or strange noise. If two motors are not running synchronically, it should be stopped immediately and restart after the problem has been solved.

Under cold state, the motor continuously starting should not be more than 5 times generally. And under thermal state, if the motor is started over again, it cannot be exceeds 3 times.

Suitable configuration of solids control system

Drilling fluid solid phase particles type, size and content are great influence to drilling fluid performance, so we must according to the drilling process requirements do suitable control. In solids control process, the matching of equipments is very important, directly influence the whole solids control effect.

Drilling fluid solids control system mainly includes three parts: drilling fluid circulating tank, drilling mud cleaning equipment, electronic control device.

Drilling fluid circulating tank should make tank size minimization under the situation of meeting requirements of drilling process, so it is easy to install and transport of equipment, and also can reduce floor space of equipment.

Drilling fluid circulating tank is composed of several chambers, can be equipped with shale shaker, desander, degasser, desilter, centrifuge, sand pump, mud agitator, etc. and also matched with all kinds of pipeline, valve, and other assist device.

According to requirement of drilling fluid purification cycle, the electronic control device is installed by the way of extension and centralization.

Before the solid control system leave factory, all of them should be installed and debugged in factory. Because the installation of solid control system is related to future drilling fluid solid control system whether can work normally and the service life of solid control equipments, so we must complete installation work strictly.

After installation must carry on the overall check, after passed examination can do the solid control system debugging. The equipments which needed to debug including shale shaker, vacuum degasser, mud cleaner, centrifuge, shear pump, sand pump, centrifuge feed liquid pump, drilling mud gun and mud agitator.
