What is the difference between API 5CT K55 tubing and Casing

API 5CT K55 tubing and API 5CT K55 Casing are essential tools for oil extraction. API 5CT K55 tubing is a pipe that is inserted into the oil well API 5CT K55 Casing during normal production of the well. From the well, the oil flow flows into the ground through the API 5CT K55 tubing and enters the gathering process. In the coal mining well, API 5CT K55 tubing, sucker rod, and deep well pump (ie “three pumping” equipment) are combined to pump oil to the ground and enter the gathering process.

API 5CT K55 Casing is a pipe that is lowered into the well after drilling, API 5CT K55 Casing and the well wall are cemented, and then perforated with a perforating gun to make the oil flow through the rock layer, cement ring, API 5CT K55 Casing flows into the bottom of the well and enters the API 5CT K55 tubing to the ground. The main functions are: 1. Reinforce the well wall to prevent the formation from collapsing; 2. Separate different oil layers and water layers to achieve stratified mining; 3. Facilitate the implementation of fracturing and acidification operations and maintenance operations. 5, the formation of oil flow channels, with API 5CT K55 tubing to achieve the purpose of oil recovery.

The order is: after the well is laid, the API 5CT K55 Casing is placed, the API 5CT K55 Casing is cemented with the well wall, and the API 5CT K55 tubing is lowered into the API 5CT K55 Casing. The API 5CT K55 tubing is equipped with a downhole tool such as an oil packer and a pump. The API 5CT K55 tubing is inserted into the sucker rod, and the sucker rod pulls the piston of the pump to reciprocate up and down. In this way, the oil is pumped to the ground.
