Research on Leakage Prevention and Plugging Technology in Oil Drilling Engineering

In order to do a good job of leak prevention and plugging in oil drilling engineering, the main factors affecting the leakage of oil drilling engineering are introduced, the commonly used leak prevention and plugging technology is analyzed, and the main application points of leak prevention and plugging technology are summarized.

The application of these leakage prevention and plugging technologies has effectively solved the leakage problem in oil drilling engineering, and better guaranteed the safe and smooth progress of oil drilling operations.

With the rapid development of society and economy, the demand for petroleum resources in all walks of life and social life is increasing day by day, and its importance is self-evident.

Against this background, the number and construction scale of my country’s oil drilling projects have increased year by year, and drilling technology has also made great progress.

In actual construction and use, leakage problems in drilling construction are prominent due to the particularity of mining technology and human errors.

Therefore, in oil field drilling construction, we must fully understand the problems existing in drilling construction, strengthen the research of various technical measures, and choose the appropriate anti-seepage and plugging technology reasonably according to the characteristics of drilling construction.

At the same time, it is necessary to continuously innovate and improve anti-seepage and leakage plugging technologies based on the actual conditions of the oil field, and actively introduce information technology to provide a reliable guarantee for the safe and efficient operation of oilfield drilling projects.

Main Influencing Factors of Oil Drilling Engineering Leakage.

Judging from the current technical level, in oil field construction, there are problems such as the determination of the location of the leak, the size of the leak, the environment around the leak, and the damage to the reservoir.

The blindness and technical limitations in the construction process will It will have an adverse effect on anti-leakage and blockage during construction.

Therefore, it is necessary to study the influencing factors of anti-seepage and plugging to ensure the scientific work of anti-seepage and plugging in oilfield drilling construction.

The location of the leak layer cannot be precise

In oil drilling, once the leakage problem occurs, it is necessary to find out the leakage layer existing during the drilling process and accurately judge the location and size of the leakage layer, which lays the foundation for the implementation of anti-seepage and plugging work.

At present, there have been theoretical studies related to hydrodynamics and oil columns at home and abroad, but due to limitations of site conditions, its feasibility is not high.

Therefore, during on-site investigation, the location of the leakage layer is still experienced staff, which leads to low efficiency of anti-seepage and plugging work.

The size of the leakage range cannot be determined

When well leakage occurs, since the leakage part is in the formation, the size of the leakage channel cannot be detected mechanically, but measures must be taken promptly to seal it.

In order to avoid further expansion of the leakage area and ensure the effectiveness of the leakage plugging work, materials The dosage should be determined according to the leakage range of the channel.

Since the size of the leakage area cannot be determined, in order to ensure that the required amount of materials is sufficient, it often leads to excessive reserves and waste of materials.

Reservoir damage

When implementing plugging technology, improper operation by oilfield operators can easily cause damage to the oil well reservoir.

When repairing the leakage layer, the supplement must be placed in the leakage tank. When adding materials, once there is an operation error, the reservoir layer will be damaged.

Not only will it affect the sealing effect of the oil field, but it will also cause great obstacles to the next step of drilling work.

Leak prevention and plugging work is highly blind

In oil drilling construction, due to various reasons, there is currently no complete technical system and management system. Normally, when dealing with emergencies on site, repairs need to be made based on the experience and subjective judgment of on-site workers.

Therefore, during drilling construction, construction workers are very blind in their operations.

If the operators themselves If there is a problem in the judgment of well leakage, it is difficult to find out the cause of the lost circulation, which also has a certain adverse effect on the correctness of the leakage prevention and plugging project.

In the long run, it will not only increase the construction cost of the drilling project, but also cause huge financial, material and personnel losses.

Leak prevention and plugging technology has limitations

When performing leakage plugging operations in well leakage areas, because operators cannot accurately understand the oil leakage situation and leakage location and other relevant information, there are many difficulties in leakage prevention and plugging technology, which seriously restricts the implementation of construction.
