With the increasing number of automobiles nowadays, we use petroleum casing when we are drilling for oil because it contains more of the corrosive substances in the crude oil, so it is necessary when we carry out the oil casing and note that when we use petroleum casing to extract oil, the casing will be very prone to corrosion. How should we prevent the casing from being corroded at this time? Then let me, to introduce you to the oil casing when used in how to carry out anti-corrosion.
(1) When we use petroleum casing to transport water, we should ensure that the quality of the water is up to standard when it is used, the quality of the water should be up to standard, and when it comes to discharging implementation of the sewage disposal. In the use of the time to strengthen the cleaning of the main water pipe to ensure that the use of oil casing after the pipeline does not remain corrosive substances. Ensure that the oil casing can be longevity when used.
(2) For injection wells that have already been put into production, we should take the work of adding some annular spacers to maintain them when we use them, and the regular addition of protective liquid like this should become a kind of system, we need to regularly add to the inside of the oil casing, the only way to ensure that the oil casing in use can be used for a long time.
(3) In the use of oil casing, there will be mechanical abrasions, these scratches will affect the corrosion of oil casing, accelerate the corrosion of oil casing, it is recommended in the use of the time can be in the tubing coupling add a rubber ring on top of it to reduce corrosion of the oil casing.
