【 摘 要 】

In view of the actual situation of Chaheji oilfield steps into the high water content development phase after several times of encryption adjustment. C30 fault block of Chaheji oilfield is taken as the research object. Combined logisitic cycle theory with the principle of material balance to determine the reasonable injection-production ratio. Firstly, the quantitative relationship between the annual oil production quantity and the annual water injection quantity of different water content ratio is determined by the logisitic cycle theory. Secondly, the relationship between the pressure recovery rate and the difference of underground injection- production fluid volume is determined by using the material balance principle. Thirdly, the relationship of injection-production ratio with water content ratio and pressure recovery rate is studied. Finally, this method is applied to determine the reasonable injection-production ratio of C30 fault block in current development situation. And the field practice shows that the method can guide oilfield development and adjustment better.
