How To Prevent Oil Casing Damage?

It is very important to prevent oil casing damage, because damaged oil casing may cause fluid leakage, pollute the environment, and even cause safety issues. So how to prevent oil casing damage? Here are some ways to prevent oil casing damage.

1. Prevent drilling damage to oil casing

In order to prevent drilling damage to the casing, two points should be noted:

(1) Petroleum casing oil wells with corresponding anti-corrosion properties should be selected according to the specific conditions at the bottom;

(2) Petroleum personnel should optimize the drilling design plan before drilling operations so that relevant personnel can reduce the wellbore curve rate, reduce stress changes in the oil casing, ensure drilling quality, and prevent damage to the oil casing during the drilling process.

2. Optimize perforation technology to ensure cementing quality

In the perforating operation, the relevant parameters of the perforating operation should first be optimized to improve the accuracy of the perforating process and avoid damage to the oil casing during the perforating operation. Relevant managers of oil companies should strengthen supervision of the implementation of the perforating process, ensure that relevant personnel strictly follow the perforating process implementation process to perform perforating operations, and ensure the quality and quality of cementing. oil casing.

3. Use anti-corrosion technology to avoid damage to oil and casings

Oil companies can use anti-corrosion techniques to avoid damage to oil and casing pipes.

The main methods are:

(1) When water is injected during oil extraction, some anti-corrosion additives should be added to the water to reduce damage to the oil casing.

(2) In the face of electrochemical corrosion, a certain current can be passed into the oil casing to realize the transfer of casing corrosion and avoid damage to the oil casing.

If there are specific applications or situations, additional measures may be required to prevent oil casing damage. The most important thing is to regularly inspect, maintain and update equipment to ensure the reliability and safety of oil and casing pipes. At the same time, follow relevant regulations and standards to ensure that operation and maintenance comply with regulations.
