Oil-based freeing stuck-pipe agent (P-FREE) is a kind of high temperature resistant oil-based freeing stuck-pipe agent researched independently by us and has been verified by experts in 1988. the product is specially used for pipe-sticking accident during drilling process. Before the advent of freeing stuck-pipe agent, foam oil was usually used for the resolution of pipe sticking related accidents. That is, an amount of diesel was pumped into well section where pipe-sticking occurred. However, due to the low density of diesel, it would arise many problems. In order to compensate the shortage, we have done a lot of research work and finally developed oil-based freeing pipe-stuck agent.
