Description

Technical Field

[0001] The utility model relates to the field of oil and gas well component testing, in particular to an oil and gas well casing wear test bench. Background Art

[0002] Oil and gas wells are holes drilled by drilling methods. Generally, after reaching the oil layer, oil and gas wells are lowered into the oil layer casing, and oil well cement is injected into the annular space between the casing and the well wall to protect the well wall and seal the oil, gas and water layers. Then, according to the requirements of oil field development, the oil layer is perforated with a perforating gun to form a channel, and the oil pipe is lowered. Using appropriate inducing flow methods, the oil and gas are raised from the bottom of the oil and gas well to the wellhead.
