The desander cleaner is used in the solid phase control system of drilling fluid.

The desander cleaner is used in the solid phase control system of drilling fluid. It is a combination of cyclone desander and vibrating screen.

Desanding cleaner designed according to the principle of particle sedimentation, the drilling fluid separation medium through sand pump produce certain pressure and velocity, along the spiral into the cyclone wall, coarser particles under the action of centrifugal force and gravity walls along the hydrocyclone vortex sink, from the
underflow port , falls below breakdown vibrating screen separation, has risen in a spiral along the hydrocyclone, the rest of the media from the overflow mouth into the third grade separation equipment desilter further purification treatment.

Installation and debugging of desander cleaner:

The desander cleaner is m+ainly composed of a vibrating screen, a shunt manifold and a cyclone. The inlet pipe and overflow pipe of the desander cleaner are symmetrical at both ends to facilitate installation.

Features and advantages of KOSUN’s vertical cuttings dryer.

In oil and gas drilling, water based mud is used in shallow Wells and oil based mud is used in deep Wells. Conventional solid control equipment can effectively recover heavy metal and useful drilling fluid items. If these solid phase parts containing heavy metals and compounds are discharged randomly without treatment, long-term precipitation will cause great harm to the surrounding vegetation, soil, groundwater and other natural environment and human survival environment.

With the constant improvement of the environmental protection requirement, puts forward higher requirements on drilling field cuttings nursing, the emergence of drilling waste purification system, not only can very good to solve the environmental problems, at the same time to the waste of the solid control system to produce secondary recycling, can maximize the retention of mud is useful at the same time, to focus again after processing of drilling cuttings curing processing, reduce on-site damage to the surrounding environment.

Features and advantages of KOSUN’s vertical cuttings dryer:

1. Self-suction device, which does not need centrifugal pump to supply drilling mud;

Daily maintenance of centrifuge

Centrifuge must have special operating and maintenance personnel, operators should check per class, record the flow rate of the machine the vibration of the main bearing, bearing temperature, working current, voltage and other data, before each downtime should be in the drum and spiral of sediment is rinsed clean, lest drum and spiral internal product materials caused by the vibration of the machine, the next time you start in the process of work, in case of sudden high electric current, should be immediately shut down feed valve, open the purge valve cleaning spiral to the working current lie screw can continue through material, after returning to normal say failure lie screw have been conversely, need to find out the reason behind the discharge fault to boot up again.

Before the centrifuge is shut down for a long time, the material in the drum should be carefully removed. Grease should be added to each lubricating part and the machine should be cleaned. Rust prevention oil should be applied to the relevant parts.

Xi ‘an KOSUN series of horizontal spiral discharge settling centrifuge is my company to introduce and absorb advanced foreign technology developed on the basis of and improvement, to develop a series of centrifuge products, mainly used in urban life waste water, industrial waste water, chemical, video, pharmaceutical, nonmetalliferous ore and similar areas of solid-liquid separation in production process.

Mud tank as an indispensable equipment in the solid control system

As the mud carrier, the mud tank is an indispensable part of the mud circulation system, which can in turn complete the weight of mud, slurry distribution, solid-liquid separation, degassing and other processes; The mud tank carries the mud circulation from the wellhead to the mud pump, and the solid phase particles in the mud are separated step by step through the corresponding solid control equipment on the tank, and the mud weight mixing system is deployed to meet the drilling process requirements.

The degassing equipment on the mud tank can remove the harmful gas in the mud, so as to ensure the environmental requirements and mud weight of the work site; Mud tank adopts electrical centralized control. In polar regions, the tanks are equipped with heating and insulation systems.

Mud tank on the supporting equipment generally: drilling fluid shale shaker, vacuum degasser, desander, desilter. Sand and mud removal machine, liquid and gas separator, mud agitator, sand pump, shear pump, centrifuge, electronic ignition device, mixing funnel, jet mixing device, mud gun, etc.

Mud tank as an indispensable equipment in the solid control system, the use of the need to pay attention to: do not let the mud tank sediment attached to the tank wall, reduce the capacity of the tank, is not conducive to cleaning.

Xi ‘an KOSUN manufacturing series mud tank is mostly square tank, the base of i-steel as the main beam plus other profiles, on the basis of meeting its strength requirements made of skid-mounted structure.

Liquid-gas separator is mainly used to deal with large bubbles in drilling fluid.

Liquid-gas separator is mainly used to deal with large bubbles in drilling fluid. Throttling and exhaust operation should be carried out after gas invasion; When overflow occurs, kill the well. Drilling fluid from the throttle manifold into the liquid gas separator, degassing treatment. The drilling fluid separated from the above two conditions also has small bubbles, which go into the vibration screen for degassing, flow to the sand bin, and then go into the vacuum degassing device for routine degassing.

During the drilling of ultra-high pressure gas Wells, the amount of gas and liquid entering the wellbore varies greatly. This requires the Liquid-gas separatorto have a wide range of handling capacity, and its handling capacity of gas and liquid volume must meet the needs of well killing construction. The following factors should be taken into consideration in the scheme design:

1. The task of the separator is to deal with continuous gas phase and large bubbles;

2. Provide appropriate dwell time to enable small bubbles to gather in a certain depth range below the liquid surface;

3. Solid cuttings cannot be deposited in the separator;

4. The separator can work normally except that the air column reaches the wellhead.

Features and advantages of the liquid and gas separator:

1. Separation and discharge of a large number of free gases in the mud system, including toxic gases, such as hydrogen sulfide;

2. The separated gas is discharged to the safe area of the wellsite through the discharge nozzle path for combustion;

3. The equipment is coated with anti-corrosion coating, which can extend the service life when dealing with corrosive gases.
