The rules of movement of injection water in the west of Ling 2 block of Sanjianfang Group of Qiuling Oilfield
Aim To study the movement law of injection water in the horizontal and on the vertical in the west of Ling 2 block of Sanjianfang Group of Qiuling Oifield.Methods Based on the sufficient study in static state of the reservoir,by the use of the results of the pressure test, the production profiles, the injection profiles and the data of production, study kinds of geology and production factors which affected and controlled the movement of injection water.Results The injection water was mainly affected by sedimentary microfacies, sandbodies distribution and reservoir property in the horizontal, and sedimentary rhythm, interayer difference vertically.Conclusion Series of adjustment measures were recommended for the enhancement of oil recovery factor.
