Drilling fluid solid control system supporting status and improvement measures

Drilling fluid solid control system is a solid control method for drilling fluid in the exploitation of oil and gas resources to separate and control it in order to improve drilling efficiency and realize the recycling of drilling fluid. Therefore, it is also known as drilling fluid purification system.

With the gradual development of drilling work in the new era, the industry attaches more importance to the improvement of drilling fluid solid control system.

1. Significance of improving drilling fluid solid control system

Drilling fluid solid control system is an essential equipment system in the exploitation of oil and gas resources, and its operational effectiveness is directly related to the overall efficiency and economic benefits of oil and gas resources exploitation.

First, improved solids control systems can improve drilling efficiency.

As a control system that acts on drilling fluid in the drilling process, the drilling fluid solid control system has the purification function of drilling fluid, and timely separation and treatment of debris, sediment and other impurities in drilling fluid to avoid the decline of drilling efficiency due to the performance of drilling fluid.

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

Drilling fluid is one of the important cost inputs in drilling construction. If the consumption of drilling fluid can be reduced, the control of drilling cost can be realized.

Finally, the improvement of drilling fluid solid control system can promote the sustainable development of drilling process. Through the improvement of drilling fluid solid control system, the resource loss of drilling process can be effectively saved, and the efficiency of drilling process can be improved, so as to realize the sustainability of drilling process and promote the modernization of drilling industry.

2. Main equipment structure of drilling fluid solid control system

Drilling fluid solid control system is composed of a variety of equipment, and the more important one is that the equipment system mainly includes three parts:

(1) Vibrating screen equipment.

The vibrating screen is the core equipment of drilling fluid solid control system, but also the main processing equipment of drilling fluid solid control system. The actual operation effect of the vibrating screen is directly related to the purification effect of drilling fluid. At the same time, the scientific operation of the vibrating screen can extend its service life, avoid damage to the vibrating screen and lead to the drilling fluid solid control system can not operate, and increase the construction cost of drilling.

(2) Cyclone equipment.

The cyclone equipment of drilling fluid solid control system is mainly used to separate the particle size of the desander and desilter. However, in the actual operation of the cyclone equipment of the drilling fluid solid control system, the distance between the desander and the desander 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 solid control system. Therefore, in the improvement of drilling fluid solid control system, it is also necessary to pay attention to the coordination and improvement of the cyclone equipment to ensure the full play of its equipment.

(3) Centrifuge.

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

3. Supporting status of drilling fluid solid control system

As the key of drilling engineering construction, drilling fluid solid control system is the core system structure of drilling technology.

At this stage, the supporting status of 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 engineering, 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 consumption of drilling materials has not been well solved, which seriously increases the cost of drilling engineering.

(2) The control process of drilling fluid solid control system needs to be optimized, and there are errors in control practice. In the actual operation of drilling fluid solid control system, the system process generally includes five parts: purification process, weight 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 drilling fluid solid control system operation. However, in the actual operation of the drilling fluid solid control system at this stage, there are still practical problems of process errors, which mainly include incomplete equipment of the solid control system and insufficient implementation of equipment maintenance. Therefore, the operational stability of the drilling fluid solid control system is reduced, which has an adverse impact on the efficiency of drilling operations.

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

In the operation of drilling fluid solid control system, the operation influence of the operator is extremely important. Only by ensuring that the operator can pay attention to all the equipment supporting the drilling fluid solid control system, can the efficient development of its system operation be guaranteed. However, during the operation of the drilling fluid solid control system at the present stage, some operators are negligent in their own work and have insufficient supervision on the operation of the drilling fluid solid control system. They only pay attention to the supervision on the operation status of some core equipment while ignoring the integrity of the overall system, which leads to the realistic problem that some equipment cannot operate normally during the operation of the drilling fluid solid control system. It not only affects the progress of drilling engineering, but also makes the situation of drilling engineering more complicated, and causes subjective impact on the operation of drilling fluid solid control system.

4. Measures to improve drilling fluid solid control system mainly include the following aspects:

(1) Vibration screen improvement measures. In the operation process of drilling fluid solid control system, the management of vibrating screen 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 problems of the drilling fluid solid control system often appear in the actual operation of the vibrating screen frame damage, mud cylinder liner leakage, top flushing pipe leakage, water hose belt leakage, drilling tool leakage and other practical problems, which not only seriously affect the progress of the drilling project, but also lead to the increase of the maintenance cost of drilling fluid solid control system equipment.

(2) Project management improvement measures. In the process of drilling fluid solid control system operation, the implementation of high-quality project management is also the key to ensure the stable development of drilling engineering. Once the implementation of project management is insufficient, it will easily lead to the occurrence of construction risks. Therefore, in the drilling fluid solid control system operation, the improvement of engineering management is also an important content of the drilling fluid solid control system improvement. In the improvement of engineering management of drilling fluid solid control system, it is necessary to establish a perfect engineering management system and implement strict engineering supervision to ensure the standardization of drilling fluid solid control system operations.

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