1. Features
■ Applicable for openhole wells, perforating completions, screen completions, vertical wells, highly-deviated wells and horizontal wells..
■ No limitation to the treatment length, performed by Coiled Tubing..
■ Dual functions: the rotary jetting together with the treatment fluids to achieve unplugging result.
■ Uniform treatment: the interval can be uniformly treated with coiled tubing

2. Technical principle
The rotary jetting nozzle will jet the treatment fluid uniformly to all ports on the base pipe of the screens:
■ It is the speed-control rotary jetting head which can give high jetting speed.
■ The target interval can be uniformly and effectively covered by coiled tubing moving.
■ Treatment fluids: resolve the plugging materials.

3. Applications
Rotary jetting services can provide a solution to the production decline due to plugging in perforations or screens in vertical wells, highly-deviated wells and horizontal wells.

4. Application results
It is widely used in Chinese oilfields, with better effects than conventional acidizing.
