Drilling operations are a crucial step in the exploration and development of oil and natural gas. During the drilling process, many problems caused by shale formations are often encountered. Because shale is water-sensitive, it is prone to hydration, dispersion, and expansion after contact with drilling fluids, leading to complex situations such as wall instability, stuck pipes, and even well wall collapse. To solve these problems, the industry uses chemical additives called shale inhibitors.

Shale inhibitor is a chemical used in the mining process. Its main function is to inhibit the release of water and gas in shale, thereby improving mining efficiency. However, there are some things to note when using shale inhibitors to ensure they are used safely and effectively. This article will introduce some things to pay attention to when using shale inhibitors.

First, it is important to select the appropriate shale inhibitor. Different shale gas fields have different geological characteristics and chemical compositions, so selection needs to be made on a case-by-case basis. When selecting shale inhibitors, factors such as their inhibitory effect, environmental friendliness, cost, etc. need to be considered, and consultation and evaluation with relevant experts are required.

Secondly, correct dosage is also key. Excessive use may lead to environmental pollution and resource waste, while insufficient use may not achieve the expected inhibitory effect. Therefore, when using shale inhibitors, it is necessary to determine a reasonable dose based on the actual situation and relevant test results and carry out appropriate monitoring and adjustment.

In addition, the storage and transportation of shale inhibitors also require safety attention. Inhibitors are usually chemicals that are corrosive and toxic, so appropriate measures need to be taken to ensure their safe storage and transportation. During storage, avoid mixing with other chemicals, avoid direct sunlight and high-temperature environments, and maintain good ventilation. During transportation, it is necessary to comply with relevant laws and regulations and take appropriate packaging and protective measures to prevent leaks and accidents.

In addition, environmental protection needs to be paid attention to when using shale inhibitors. Inhibitors may have certain impacts on soil, water, and ecosystems, so measures need to be taken to reduce their impact on the environment. In the process of using inhibitors, environmental protection regulations should be observed, inhibitors should be used and handled rationally, and avoid contamination of soil and water sources. At the same time, the impact of inhibitors on the environment should be regularly monitored and evaluated, and corresponding measures should be taken for repair and treatment.

Finally, you need to pay attention to safety precautions when using inhibitors. Inhibitors may cause certain harm to human health, so corresponding safety precautions need to be taken when using inhibitors. Operators should wear appropriate protective equipment such as gloves, goggles, and protective clothing to avoid direct contact with inhibitors. At the same time, regular health examinations should be carried out to detect and deal with health problems related to inhibitors in a timely manner.

In short, when using shale inhibitors, you need to pay attention to the selection of appropriate inhibitors, correct dosage, safe storage and transportation, environmental protection, and safety protection. Only by complying with relevant regulations and measures can we ensure the safe and effective use of inhibitors and improve the efficiency and sustainable development of page mining.
