What is a Casing Pipe?

  Oil casing pipes, also known as production casings. It is the last layer of casing in the oil and gas well casing process, from the wellhead down to below the oil and gas layer.   The depth of the casing casing is basically the depth of the well.   The function of the oil casing is the passage of oil and gas to the ground, which isolates the oil and gas from the entire formation to ensure that the oil and gas pressure does not leak. After the oil and gas wells are transferred into production, the quality of the oil casings must be guaranteed to maintain a certain number of years of exploitation.   The cementing quality of the oil casing is related to the exploration well, which is the key to oil and gas testing. On the other hand, it is related to the production well, which directly affects the life of the well.The cement sealing height between the oil casing and the borehole wall is at least 500 m above the oil and gas layer or 200 m above the upper casing.   The main differ...
