SRC & Vibration Cementing
Overview

Self-rotating casing running and vibration cementing technology is an innovative solution to the cementing problem of adjustment wells in old oil fields. Through the combined application of eccentric self-rotating module, scraping module and vibration cementing module, this technology effectively solves the problems of difficult casing running, low cementing displacement efficiency in horizontal and high inclined sections, poor cementing quality and so on, and improves cementing quality, which is suitable for various well conditions and casing sizes.

Eccentric self-rotating module: free to rotate, avoiding obstacles and realizing smooth casing running.


Scraping module: reduce the running resistance of casing string and improve the running efficiency.


Bidirectional vibration cementing tool: produces radial and axial vibration waves to improve the efficiency of slurry replacement in annulus.


High reliability: easy to install and operate, suitable for cementing vertical wells, directional wells and horizontal wells.


High temperature resistance: up to 160℃.


Drillability: The tool itself can be drilled through.
Improve production efficiency: by improving cementing quality, reduce workover times and reduce production cost.


Improve the safety performance: effectively avoid the complicated situation in the cementing process and improve the operation safety.


Technical innovation support: provide customers with cutting-edge cementing technology and enhance market competitiveness.
