Study on the Preparation of Polymer Gel System with Oilfield Wastewater

The solvent that is used to make the gel is water which is widely applied on the oil-field. The solvent is actually inject water. The chromes receipt which were already used on the oil- field is listed in the experiment, The research is that according to the inject water which come from Zhuangxi and Feiyan Beach oil field to make the gel, then to observe whether the polymer system gelatinize, which one is more practical and economical. The comparison was carried out in the experiment, the gel that is made of distilled water contrast with the get which is made of Zhuangxi and Feiyan Beach inject water, then observe the affecting factor of gelatinization, such as pH, temperature, drug style, concentration. According to the experiment, the intensity of the gel which is made of the Zhuangxi oil field inject water with the HPAM of Changan Group is the largest, however initial setting time is the shortest, the intensity of Feiyan Beach gel is smallest, initial setting time is the second .HPAM from Japan which is made up by water from Zhuangxi can be gelatinized at the initial pH, but The gel which is made of distilled water and Feiyan Beach can’t be gelatinized, the adjustment of the pH and the increasing concentration can make the polymer gel.
