利用系统分析方法进行单井措施优选

油井措施增油一直是油田控制产量递减、含水上升的主要做法，但是随着油田开采程度加深，地下油水分布十分复杂，选择油水井措施难度越来越大。为此，运用系统分析方法进行单井措施优选，通过对区块水驱油、水驱水、井间干扰以及油井的液、油、含水率间关系，综合判断出区块内滞留区、死油区和动用好的区域，指出今后挖潜方向。此方法均应用动态数据，客观性较强、准确性较高，克服了以往选择单井措施的盲目性和主观性。并将该方法在大庆油田杏八、九区基础井网提液试验过程中得到应用，效果较好。

Single Well Measure Optimizing by Using Systematic Analysis Method

Increasing the oil production of oil wells by taking measures has always been a key method for controlling oil production decreasing and water cut increasing.But as the deepening development of oil field, it has been more and more difficult to select measures. In this paper, single well measure optimizing by using systematic analysis method is introduced, i e. through analysis of water flooding oil, water flooding water, inter well interference and relationship between fluid, oil and water cut of oil wells, the stagnant, bypassed and well produced blocks are comprehensively judged, pointing out the direction for future potential tapping. Dynamic data is used in this method resulted in high accuracy and strong objectiveness, overcoming the subjectiveness in former single well measure selection. The method has been applied during the process of fluid enhancing test in basic well pattern in No 8 and No 9 blocks in Daqing oil field, and has achieved relatively good results.
