Well cleaning service
Heli well cleaning service works on provide well cleaning service in complex well condition, such as serious leakage and sand cementation in the pit. Venture negative pressure tools which hydraulic structure has been optimized can work on sand cleaning efficiently in serious leakage well. The bottom of the tool can be connected to Heli efficient milling tool, smashing the cemented sand. Venture tools are more extensive used in packer milling operation, the packer debris after milling will be captured by venture tools rather than back to ground, which overwhelmingly reduce the risk of sticking by the upward process of debris.
Heli well cleaning service is already widely used in domestic and international oil fields and have shown that this method is effective. Under the premise of assurance of project operation, protecting the oil layer supported by smaller cycle pressure.
