Study on Adjustment Scheme of Karamay Oil Field

Abstract

Seven East District of Karamay Oilfield reservoir up to the middle and late period of development, which has been in high water cut stage. To solve the main problems existing currently in the process of development in the study area, using numerical simulation software to do the fine history matching of formation pressure, cumulative oil production, water cut, cumulative water development indexes, quantitative analysis of remaining oil distribution in the horizontal and vertical, to make it clear that the distribution of remaining oil in the reservoir zone of enrichment; according to the distribution of remaining oil enrichment area and main controlling factors, proposing development and adjustment suggestions, providing a scientific basis for Karamay Oilfield to improve ultimate recovery.
