In the process of oil exploration and development, a large amount of waste drilling fluid will be left at the drilling site.

In the process of oil exploration and development, a large amount of waste drilling fluid will be left at the drilling site. The solid-liquid separation technology of drilling fluid is faced with many difficulties that are difficult to solve objectively.Both domestic and foreign drilling fluid solid-liquid separation technology problems, are to go through a long period of practical application, in the process of practical use to obtain some applicable solid-liquid separation technology experience.

Drilling fluid solid-liquid separation technology includes: direct landfill method, land tillage method, injection formation method, solidification method, incineration method, cement slurry conversion method, solid-liquid separation method.Among these drilling fluid solid-liquid separation technologies, mechanical solid-liquid separation is the most promising one.This technique not only reduces the environmental pollution of liquid phase, but also reduces the environmental diffusion rate of pollutants in the residue and the degree of secondary pollution.

Mud curing treatment system is used to treat cuttings or drilling waste.

Mud curing treatment system is used to treat cuttings or drilling waste. Develop equipment to handle cuttings from oil field drilling, trenchless construction, municipal engineering and other fields. During the operation of the mud curing system, mechanical friction and wear will occur during the operation of waste and equipment. The maintenance and maintenance of the mud curing equipment should be aware of the following:

1. The vibration motor and the screw conveyor, the driving motor of stirring curing treatment equipment and other equipment shall be regularly added with lubricating oil, which can effectively protect the curing device: reduce mechanical friction, prevent mechanical wear, seal dust and metal corrosion. Prevent unnecessary friction and wear of curing equipment. Functions of grease: lubrication, protection and sealing. Reduce mechanical friction, prevent mechanical wear, seal dust and metal corrosion.

2. Regularly check the oil consumption of the mixer and screw conveyor and whether the seals are worn.

3. The abnormal operation of electrical components should be timely cut off the power supply, check the fault, repair the line, so as to avoid causing safety accidents.

Precautions for mud agitator

Precautions for mud agitator:

1. Check whether the selection of mud agitator is correct and whether the actual conditions are consistent with the specified conditions;

2. The cable protection of the mud agitator in the mud tank includes two kinds of hard steel pipe and metal hose to ensure the sealing of the pipe connection;

3. Use 0-500v megohm meter to check that the ground insulation resistance of the main cable of the motor should not be less than 5 megohm. Disable megohm meter to check the control cable to avoid damaging the electrical components inside the submersible mixer.

4. If the power supply is far away from the use of the mud agitator, line damage should be considered. The cross-sectional area of the cable should be increased.

5. Power cables, grounding cables and control cables on the mud mixer shall be connected with the wiring terminals of the control cabinet (box) one by one;

6. The earth wire of the mud mixer is a two-color wire (yellow/green), which is 50mm longer than other wires for safety;

7. Mud agitator control cables: 4 cables, 3 thin and 1 thick. Measure on and off with a multimeter.

8. Before the final installation of the mud mixer, it should face the impeller direction, and the impeller should rotate anticlockwise. If the rotation direction is incorrect, the position of any two lines in the three-phase line on the control cabinet or terminal box can be changed to change the rotation direction. If several mud agitators are connected to a control cabinet or terminal box, each mud agitator must be inspected separately.

9. After closing, don’t start the blender immediately, should through the control system to the introspection of mud mixer, such as found that failure occurs (electric control ark appear flashing alarm or alarm alarm), should check and troubleshooting, before you start, if the motor does not turn, should quickly decisively switch, should check and troubleshooting, so as to avoid damage to the motor;

10. After starting the mud agitator, pay attention to the observation of the motor, line voltmeter and ammeter. If there is any abnormal phenomenon, stop the machine immediately to find out the cause, and remove the fault before starting the switch again;

11. Several mud agitators cannot be started at the same time, and shall be started and stopped one by one;

12. Mud mixer shall not run empty tank for a long time.

As the “last mile” of sludge treatment, how to better treat sludge.

As the “last mile” of sludge treatment, how to better treat sludge has become a difficult problem for sewage treatment plants and local governments.

Sludge generally refers to the product of water purification in sewage treatment plants. As the product of sewage treatment, it mainly comes from the primary sedimentation tank, secondary sedimentation tank and other technological links. The sewage becomes clear after entering the sewage treatment plant, but the pollutants in the water are not eliminated completely, they are only concentrated and concentrated in the colloidal sludge deposited. It is understood that each cubic meter of sewage after treatment sludge production (according to the moisture content of 80%) is generally about 5 tons -10 tons, the specific output depends on the inlet water quality, sewage and sludge treatment process and other factors.

How much sludge does our country produce every year? Sludge as a byproduct of sewage treatment, its production is also increasing. Calculated with 80% water content, the total annual sludge production in China is expected to exceed 60 million tons by 2020.In addition, according to public information, about 30-50% of COD, 30%-45% of nitrogen and 90% of phosphorus in sewage were transferred to sludge. From the perspective of energy saving and emission reduction, if sludge is not treated in time, sewage treatment is equivalent to only one third of the process.

At present, China’s urban sewage treatment plants have basically achieved the initial reduction of sludge, but not the stabilization of sludge treatment. In the early stage, due to the absence of strict sludge discharge supervision, sewage treatment system and sludge treatment system were generally separated, and sludge treatment system was simplified or even ignored as far as possible. In sludge treatment industry, there are many treatment processes, different sludge often have different treatment methods. Traditional sludge disposal generally adopts sanitary landfill, incineration power generation, soil utilization and other methods.

The translational elliptical vibrating screen is the fourth generation of new mud vibrating screen.

The translational elliptical vibrating screen is the fourth generation of new mud vibrating screen. Before the mud vibrating screen mainly choose linear vibrating screen, but now more and more drilling companies choose translational elliptical vibrating screen.

With the development of drilling technology, drilling depth is deeper and deeper, and mud requirements are more and more strict. Some complex geological conditions under the ordinary mud shaker can no longer meet the requirements of use. Moreover, the performance of the ordinary drilling vibrating screen is not very stable, and the effect of drilling vibrating screen treatment can not be adapted according to the drilling geology, often there will be some run-slurry or “horseshoe effect”. The appearance of the translational elliptical vibrating screen has solved these problems.

Advantages of translational elliptical vibrating screen:

1. Treatment capacity is increased by 25%-30% compared with linear vibrating screen;

2. Can adapt to a variety of geological conditions drilling mud recovery and purification;

3. The excitation force can be adjusted;

4. Linear vibrating screen has the advantages of translational elliptical vibrating screen have.
