Abstract:

In order to deal with the waste drilling fluid in Jiangsu oilfield, we proposed to add additives to the waste drilling fluid, and made a kind of waste drilling fluid profile control agent. In the laboratory experiments, by the physical properties of waste drilling fluid and particle size, we filtered out the suitable profile control formula. Then we obtained the optimum dosage of each additive from the experiments: the suspension of 0.20 %, dispersant 0.30 % and curing agent 5.0 %. The developed waste drilling fluid profile control agent had good suspension stability, curing properties and plugging performance. It could not only solve the problemsof waste drilling fluid, but also reduced the production cost of plugging agent, moreover, it had great significance to the production of oil.

Key words: waste drilling fluid, plugging water profile, treatment agent, plugging rate
