Research and Evaluation of Water-Based Pipe Freeing Agent SJK-1

Sticking pipe has been being a common problem in drilling process. There are several techniques to solve sticking pipe which caused by differential pressure. But all of the techniques are inefficiency and the common oil-based pipe freeing agent is unsafe and pollution. So the water-based pipe freeing agent, SJK-1, has been developed. This kind of pipe freeing agent is cheaper, safer and more effective.
