Maintenance and management of solid and liquid separation equipment and drilling waste disposal equipment produced by KOSUN

Equipment wear and maintenance

The concept of wear and tear: there are two types of wear and tear that can occur over a long period of time. One is material wear, refers to the use of mechanical forces caused by friction, vibration loss; The second is base wear. If the equipment is scrapped due to improper operation or other reasons, it cannot be used again. Or because of the progress of science and technology, the equipment with better performance and efficiency of the same purpose keeps appearing, which reduces the “value” of the original old equipment. Formally, the former is called visible wear and the latter is called invisible wear.

Equipment maintenance job category: equipment maintenance includes lubrication, corrosion protection, parts control and replacement, etc. Generally, equipment maintenance is classified as follows.

1. Daily maintenance. This is the external maintenance of the equipment, such as cleaning, inspection, refueling, etc., which is undertaken by the operator as part of the handover.

2. Primary maintenance. Inspection and maintenance of vulnerable parts of equipment. Including cleaning, lubrication, equipment parts and key disassembly, adjustment, etc., generally under the guidance of full-time maintenance personnel by the operator.

3. Secondary maintenance. Carry out strict inspection and repair of equipment. Including replacement parts, repair equipment precision, etc. By full-time maintenance technical workers.

4. Minor repairs. This is a minimal amount of local maintenance, with only local repairs, replacements and adjustments.

5. To repair. This is one of the biggest planned repairs. Including the total dismantling of equipment, inspection, repair, replacement, adjustment, and finally reassembled into a new machine, and the appearance of the equipment for repainting or painting. Usually only a few years or even ten years to carry out, can be completed by professional (repair) factory.

Principles of equipment maintenance work

Pay equal attention to maintenance and planned overhaul, and give priority to prevention. Adhere to good maintenance, can reduce the equipment “wear” degree; Timely maintenance and can prevent small problems into big problems.

Adhere to the principle of maintenance first, production later. Production must have good equipment, so cannot do without maintenance. In order to catch up with the production task, it is not allowed to make the maintenance equipment “operate with disease”, so as to cause serious damage or accident, which will bring greater loss to the production.

Adhere to the principle of combining professional repair with mass maintenance. Workers are the users of the equipment, they are most familiar with the performance and technical status of the equipment; And professional repair personnel has the advantage such as special knowledge and overhaul means, so equipment maintenance should be given priority to with major, group union only.

Recently, 2 sets of ZJ15 fixed control system produced by KOSUN were successfully sent to the Ukrainian project site.

Recently, 2 sets of ZJ15 fixed control system produced by KOSUN were successfully sent to the Ukrainian project site. Previously, KOSUN invited customers from the Ukrainian market to visit the factory to inspect the production process and work progress, and the customers gave a high evaluation of KOSUN’s professional products.

KOSUN production of ZJ15 drilling solids control system is a set of mechanical and electrical control of sludge treatment system, drilling mud can be hierarchical processing, at the same time, the drilling mud can be mixed, degassing, aggravating, mixing, can also be used to supply of wellhead mud, the Ukrainian market customer order system by mud mud tank, mixing tank, rotation of the crane and solids control equipment. The whole system includes vibration screen, vacuum deaerator two-stage solid control equipment, mud mix weight system, mud supply system, electrical control system, lighting system, etc. The surface coating of the system is durable, which can ensure that the system can be used in the wear and corrosion environment.

This ZJ15 drilling solids control system has several special designs of important processes, which can be used to grade drilling mud. The mud can also be weighted, mixed and stirred. Drug canisters and pipelines can provide slurry batching for the system; Mud system can be mixed and matched for system mud; Supply silo and supply line can supply mud supply for wellhead mud defect; Mud gun pipeline and mixing system can fully stir and mix in the mud tank; The clean water collection can provide water channel for slurry distribution and flushing tank surface.

ZJ15 drilling solids control system adopts multi-functional design, so that the system can meet the requirements of different mud systems, and each system and process can work independently or simultaneously.

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.
