چکیده:

Mineral scale formation and deposition on downhole and surface equipments is a major source of cost and reduce production to the oil industry. Chemical scale inhibitors delay, reduce or preventscale formation when added in small amounts to normally scaling water. However their poor biodegradability and the phosphorous content can make them an inacceptable burden on the environment. The oil industry is currently facing severe restrictions concerning the discharge ofoilfield chemicals into the environment due to the new governmental regulations. Therefore, many efforts are done to develop new scale inhibitors that are consistent with environment. In this paper, the effects of environmentally friendly additives called green inhibitors on formation and growthof sparingly soluble salts are presented. In addition, preparation of the new green inhibitor was investigated. Inexpensive monomers were selected to be synthesis of polymer composite. Feasibility of the polymer composite was completely investigated using carbonate calcium, as model mineral scale.Applicability of the prepared polymer composite was thoroughly examined by prevent of formation mineral scaling. Chemical structure of polymer composite contributes to different interaction between cations and the various functional groups on the composite, making the suitable inhibitor for mineral scale
