Hydrophobic Association Complex As The Development Of The Colloidal Dispersion Gel

At present, our country majority water-poured development oil field has entered the high containment water stage, thus it is very important to carry on the deeply deal with the stratum. The water-poured well depth profile control technology is one of effective solution methods. The CDG depth portion profile control t technology is a new technology of enhancing the recovery ratio, at the same time, and has the profile control and the drive oil function. In view of the oil field operation area geological development characteristic and the convention colloidal dispersion gelatin insufficiency, this article has developed the hydrophobic association AP-P4 primary new agent CDG system, has evaluated the CDG performance by the transformed the pressure and the viscosity , has observed the CDG microscopic structure through the scanning electricity mirror, it is prove that the new CDG is the "true" dispersible gelatin. In this article filled , it carries on the CDG profile control and drive oil experiment in liner model, layer model and so on. It also compares with main the HPAM primary agent CDG system. The result indicates in the special permeability level, the new CDG has the good poured nature, the good washable characteristic, section plane improvement and the good effect of drive oil as well as sealing off the high permeability level to force the successor liquid flow to change.
