1. Inner column cementing: Insert the plug connected with the drill string into the sealing socket of the casing collar or floating shoe, and inject the cement through the drill string to cement the well, which is called inner column cementing. Internal pipe cementing is mainly used for the cementing of large size (16′′-30′′) conduits or surface casings.

2. Cementing with a single-stage double rubber plug: First, set the casing to the desired well depth, and then install the cement head, rubber plug (top plug and bottom plug), circulate the cement, fight the spacer fluid, cast the bottom plug, then inject the cement slurry, and then cast. Plug, start for the mud. The bottom plug fell on the float collar and was punctured. The top plug bumps and cementing ends.

3. Cementing of the tail pipe: Cementing of the tail pipe is to send the tail pipe to the hanging design depth with the drill pipe. After hanging the tail pipe on the outer casing through the tail pipe hanger, the tail pipe hanger is first set and then started. Cement injection, drill pipe rubber plug displacement, drill pipe rubber plug cut tail pipe rubber plug coincides with tail pipe rubber plug, down to the ball seat contact pressure, cementing end.
