When we use the casing pipe to extract oil , API casing pipe will be very easy to corrosion. When we use the oil casing transport water, it should be guaranteed in the use of the time, and the water quality should be meet the standard, but also in the discharge of the time to implement the pollution dispensing. In the use of the time to strengthen the main water pipe cleaning work, to ensure that the casing pipe after the use of the pipeline does not remain inside the corrosive substances and the casing pipe in the use of the time can be longevity.
For the injection wells that have been put into production, we should take the work of adding some protection solution to the inside when we are in use and the casing pipe can be used for a long time.
In the use of casing pipe, there will be mechanical abrasions will affect the corrosion of casing pipe, in order to accelerate the corrosion of casing pipe, it is advisable to add a rubber ring to the tubing coupling during use so that the corrosion of the casing pipe can be reduced.
