Current status and improvement measures of drilling fluid solids control system

The drilling fluid solid control system is a method of controlling the solids in the drilling fluid during the exploitation of oil and gas resources. It is used to separate and control the drilling fluid to improve the drilling efficiency and realize the recycling of the drilling fluid. Therefore, it is also called the drilling fluid purification system.

With the gradual development of drilling work in the new era, the industry has gradually increased its attention to the improvement of the drilling fluid solid control system.

1. The significance of improving the drilling fluid solid control system

As an indispensable and important equipment system in the exploitation of oil and gas resources, the effectiveness of the system operation is directly related to the overall efficiency and economic benefits of oil and gas resource exploitation.

First, the improvement of the drilling fluid solid control system can improve the drilling efficiency.

As a control system that acts on the drilling fluid during the drilling process, the drilling fluid solid control system has a purification function for the drilling fluid, and timely separates and treats impurities such as cuttings and mud in the drilling fluid to avoid the decrease in drilling efficiency due to the performance of the drilling fluid.

Secondly, the improvement of the drilling fluid solid control system can reduce the drilling cost consumption.

In drilling construction, drilling fluid is one of the important cost input contents. If the consumption of drilling fluid can be reduced, the drilling cost can be controlled.

Finally, the improvement of the drilling fluid solid control system can promote the sustainable development of the drilling process. By improving the drilling fluid solids control system, it is possible to effectively save resource loss in the drilling process and improve the efficiency of the drilling process, thereby achieving sustainability of the drilling process and promoting the modernization of the drilling industry.

2. Main equipment structure of the drilling fluid solids control system

The drilling fluid solids control system is composed of a variety of equipment, and the most important of them is that the equipment system mainly includes three parts:

(1) Vibrating screen equipment.

The vibrating screen is the core equipment of the drilling fluid solids control system and the main processing equipment of the drilling fluid solids control system. The actual operation effect of the vibrating screen is directly related to the purification effect of the drilling fluid. At the same time, the scientific operation of the vibrating screen can extend its service life and avoid damage to the vibrating screen, which will cause the drilling fluid solids control system to fail to operate and increase the construction cost of drilling.

(2) Cyclone equipment.

The cyclone equipment of the drilling fluid solids control system is mainly used to separate the sander and desilter for particle size. However, in the actual operation of the cyclone equipment of the drilling fluid solids control system, the distance between the desander and the desilter is relatively close, and the practical problem of repeated operation of the equipment often occurs, which not only leads to the waste of drilling resources, but also limits the performance of the drilling fluid solids control system. Therefore, in the improvement of the drilling fluid solids control system, it is also necessary to pay attention to the coordination improvement between the cyclone equipment to ensure the full play of its equipment function.

(3) Centrifuge.

The centrifuge is also the main equipment of the drilling fluid solids control system. The power of the centrifuge is an important guarantee for the stability of the drilling process. In the improvement of the drilling fluid solids control system, appropriately increasing the power of the centrifuge is also an important way to improve the stability of the drilling process.

3. Current status of the supporting system of the drilling fluid solids control system

As the key to the construction of drilling engineering, the drilling fluid solids control system is the core system structure of the drilling process.

At present, the current status of the drilling fluid solid control system is mainly reflected in the following aspects:

(1) The loss of drilling materials is large, which is not conducive to drilling cost control. In drilling projects, the consumption and actual utilization rate of drilling materials directly determine the actual effect of drilling cost control. However, in the current drilling fluid solid control system, the problem of excessive drilling material consumption has not been well solved, which seriously increases the cost of drilling projects.

(2) The control process of the drilling fluid solid control system needs to be optimized, and there are errors in the control practice. In the actual operation of the drilling fluid solid control system, its system process generally includes five parts: purification process, weighting process, mud gun process, mud pump suction process and the final water process. Only the precise operation of each process can ensure the high efficiency of the drilling fluid solid control system operation. However, in the actual operation of the current drilling fluid solids control system, there are still practical problems of process errors, mainly including incomplete solids control system equipment and insufficient equipment maintenance. Therefore, the stability of the operation of the drilling fluid solids control system has decreased, which has an adverse impact on the efficiency of drilling operations.

(3) The comprehensive quality of the operators of the drilling fluid solids control system needs to be improved, and their work is greatly affected by emotions.

In the operation of the drilling fluid solids control system, the influence of the operator's operation is extremely important. Only by ensuring that the operator can pay attention to all the equipment of the drilling fluid solids control system can the efficient operation of the system be guaranteed. However, in the current operation of the drilling fluid solids control system, some operators are negligent in their own work, and the supervision of the operation of the drilling fluid solids control system is insufficient. They only focus on the supervision of the operating status of some core equipment and ignore the integrity of the overall system. This leads to the practical problem that some equipment cannot operate normally in the operation of the drilling fluid solids control system, which not only affects the progress of the drilling project, but also makes the situation of the drilling project more complicated, causing subjective influence on the operation of the drilling fluid solids control system.

4. The measures to improve the drilling fluid solids control system mainly include the following aspects:

(1) Vibrating screen improvement measures. In the operation of the drilling fluid solids control system, the management of the vibrating screen cloth is the key management content, which is directly related to the consumption of drilling materials. In some drilling engineering operations, due to the low quality of the vibrating screen cloth, the actual operation of the drilling fluid solids control system often encounters practical problems such as damage to the vibrating screen frame, leakage of the mud cylinder sleeve, leakage of the top area flushing pipe, leakage of the hose, and leakage of the drill bit. This not only seriously affects the progress of the drilling project, but also leads to an increase in the maintenance cost of the drilling fluid solids control system equipment.

(2) Engineering management improvement measures. In the operation of the drilling fluid solids control system, high-quality engineering management implementation is also the key to ensure the stable development of the drilling project. Once the engineering management is not implemented enough, it is easy to cause construction risk problems. Therefore, in the operation of the drilling fluid solids control system, engineering management improvement is also an important part of the improvement of the drilling fluid solids control system. In the improvement of the engineering management of the drilling fluid solid control system, a sound engineering management system must be established and strict engineering supervision must be implemented to ensure the standardized operation of the drilling fluid solid control system.

5. The improvement of the drilling fluid solid control system is of great significance to the development of drilling engineering operations in the new era. It can not only extend the service life of the equipment, but also save drilling materials, realize the control of drilling fluid performance, improve the economic benefits of drilling fluid solid control system operations, and comprehensively promote the development and progress of my country's drilling engineering industry.
