There are three types of mud shale shaker motion.

In the process of oil drilling drilling fluid from internal carotid out through shale shaker, then in other solids control equipment, in the solid phase removal equipment of shale shaker is itself a filterability spate separation equipment, in the mud of a complete set of cleaning system, it has the first, the characteristics of fast drilling fluid solid phase separation, at the same time is also a kind of economic, efficient spate separation equipment.

There are three types of mud shaker motion: circular, elliptical and linear motion, the oscillator in the center of gravity, will produce circular motion; When the oscillator is above the center of gravity of the system, elliptic motion is generated. However, for elliptic motion, the screen surface must have a slope in order to utilize the conveying cuttings, but the screen capacity will be reduced. The linear motion is to put the oscillator in front of the center of gravity of the system, making the screen frame produce linear motion, thus clearing the solid phase. The vibrating screen moves in a straight line with its fixed cuttings transfer speed. The screen surface can be flat or slightly tilted.

The ES series elliptic vibrating screen of KOSUN adopts the long tube vibrating motor as the power source, the performance is superior, the structure is reasonable, the operation is stable, the life is long, the maintenance cost is low. Under the same conditions, compared with other types of shaker, drilling mud processing capacity and sand transport and discharge capacity can be greatly improved, and can effectively overcome the “screening”, “screening paste” phenomenon.

KOSUN LS series linear vibrating screen using the vibration motor excitation to cheer for the vibration source, make the material being thrown up on screen, at the same time, forward a straight line with low consumption, high output, simple structure, easy maintenance, fully closed structure, no dust overflow, and the advantages of automatic discharge, more suitable for assembly line, at the same time family newsletter QZS linear vibrating screen can also be adjusted through the AWD regulating series of solid separation effect.Linear vibrating screen has obvious advantages in the treatment of large displacement drilling fluid. In this condition, the strong excitation force output by the linear vibrating screen can quickly remove a large number of solid phases through efficient linear vibration trajectory, which can effectively remove large particles in the drilling fluid.

Drilling fluid linear vibrating screen in the processing of drilling fluid.

The linear vibrating screen USES the short or long tube vibration motor as the power source, the performance is superior, the structure is reasonable, the operation is stable, the life is long, the maintenance cost is low. Under the same conditions, compared with other types of shaker, drilling mud processing capacity is stronger, sand transport chip capacity is greater.

Purpose of linear vibrating screen: LS series vibrating screen is the first stage solid control equipment for the processing of drilling mud, which is more suitable for the occasions requiring large handling capacity. Solid particles with particle size greater than 76 microns in drilling mud can be separated. Application: large oil rig, large trenchless rig, shield engineering, river dredging engineering, etc.

Drilling fluid linear vibrating screen in the processing of drilling fluid if the phenomenon of running mud?It is understood that this is mainly related to the high solid content in the drilling fluid, mud viscosity, cuttings dispersion and other screening material factors;It is related to the condition of small vibration force, high mesh number and small screen area of drilling fluid vibrating screen.It also has a lot to do with the direction and position of the input buckle of the vibrating screen during the field installation, which can be analyzed step by step from the following points:

1. Regularly check the steering of the motor;

2. Unreasonable mesh number;

3. The formation and mud conditions affect the treatment capacity;

4. Check the amplitude of the shaker;

5. Check whether the distribution of liquid flow on the screen frame is reasonable.

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.

Xi ‘an KOSUN drilling fluid solid-liquid separation treatment system can recover and treat drilling fluid waste, reduce treatment costs, recover useful mud or water, realize resource reuse, avoid waste pollution to the environment, and meet the local government regulations on waste environmental requirements.

Features:

1. High integration of the system and equipment to meet the needs of centralized processing while drilling or after drilling;

2. Strong mobility, compact assembly, easy transportation, easy operation, high processing efficiency;

3. The daily treatment capacity can reach 300m, the treated solid moisture content is between 15% and 17%, and the solid oil content is less than 5%. The effective separation can recover a large amount of drilling fluid, which can be reused in the mud circulation system;

4. Integrated programmable logic controller, with automatic alarm indicator, can monitor temperature, torque, oil quantity and running time, easy to operate, safe and reliable;

5. Mild treatment conditions, low treatment cost, wide application, economic and practical;

6. Highly adaptable, able to handle drilling waste under different mud systems.
