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.

Use and maintenance method of KOSUN SP series shear pump.

Oil drilling fluid (mud) is mainly composed of four parts: water, active solid phase, inert solid phase and chemical treatment agent. According to the proportion and interaction of each component, different components and different properties of mud can be formed. Therefore, mud composition is the key factor to adjust the performance.

In the preparation and treatment of mud, the traditional preparation method is difficult to achieve the high shear force required for direct hydration of soil and polymer, so it requires a long preparation and treatment time. The SP shear pump developed by KOSUN can quickly prepare high performance mud, greatly shorten the preparation time of mud and improve the economic benefit of drilling.

Use and maintenance method of KOSUN SP series shear pump:

1. After each use, circulate the pipeline and shear pump with clean water to avoid debris blocking the flow path and nozzle of the impeller;

2. Check the machine oil level of the oil pool in the support before use. If it is insufficient, it should be replenished.

3 packing box packing and mechanical seal two.When the seal fails, it should be replaced in time.

4. When using the mechanical seal, it is strictly forbidden not to empty the liquid, so as to avoid damage to the mechanical seal. When the lubricating and cooling oil of the mechanical seal is insufficient, it should be timely supplemented.

Source of oily sludge

1. Oily sludge generated by crude oil exploitation

The oily sludge generated in the process of crude oil exploitation mainly comes from the ground treatment system. The oily sludge generated in the process of oil production sewage treatment, together with the flocs formed by the water purification agent added in sewage purification treatment, the corrosion products and scale of equipment and pipelines, and bacteria (corpse), etc., constitute the oily sludge. This kind of oily sludge generally has the characteristics of high oil content, high viscosity, fine particle size and difficulty in dehydration, which not only affects the quality of crude oil, but also affects the water quality of injection in profile control of injection Wells and leads to the difficulty in reaching the standard of effluent.

2. Oily sludge is generated in the process of oilfield technology

Oily sludge may also mainly come from oil storage tanks, sedimentation tanks, sewage tanks, grease trap bottom sludge, oil sands and sludge removed from oil and water treatment facilities of refinery, light hydrocarbon processing plants and natural gas purification devices, as well as crude oil and oily sludge landed from drilling, operation and pipeline perforation. When storing oil in oil storage tank, a small amount of mechanical impurities, sand grains, soil, heavy metal salts, paraffin and asphaltene and other heavy oil components in oil products are deposited at the bottom of oil tank, forming oil sludge at the bottom of tank. In addition, the sewage from primary settling tank, secondary settling tank and well washing water recovery tank can also produce oily sludge.

3. Oily sludge generated from the sewage treatment plant of the refinery

The oily sludge in the sewage treatment plant of the refinery mainly comes from the bottom sludge of the oil separation tank, the scum of the flotation site and the bottom sludge of the original oil tank, commonly known as “three mud”. These oily sludge consists of different compositions, usually with an oil content of 10%~50%, an moisture content of 40%~90%, and a certain amount of solids.
