摘要 FD33油田经过7年的开发，目前已进入中含水阶段，含水率已达到53%，该阶段含水上升速度加快，产液量增加，产油量下降，开采难度增大，开采费用提高，是油田开发的重要阶段。所以，必须对其含水上升规律进行研究并进行相关的调整措施，以保证油田能够较长时间的高产稳产。 目前国内常用水驱特征曲线法来研究水驱油田的开发指标。本文对常用的超过20种水驱特征曲线进行了分类总结，并作出了FD33油田的各类水驱特征曲线，通过9种常用水驱特征曲线预测了该油田的相关的开发指标，经过分析对比选取了甲型水驱特征曲线的预测结果为最终预测结果。FD33油田的水驱控制地质储量的预测结果为2419.35×104t，可采储量预测结果943.9×104t，预测水驱采收率为39.1%。 总结了FD33油田的含水上升特征，并从机理上对含水上升的影响因素进行了分析，最后提出了相关的控水措施。 关键词：含水率；采出程度；水驱特征曲线； 动态预测 Abstract After years of development, FD33 oilfield has entered the later high water cut stage; the current water cut has become 53%. In this stage the speed of water cut increasing speeds up, the liquid production increases, the oil production declines, the development becomes more and more difficult and the production costs increases, it’s the most important stage to the development of FD33 oilfield. So it is necessary to study the performance of water cut of FD33 Oil Field and do some adjusting procedures to ensure that the oilfield can product highly and firmly in a long time. Currently the water displacement curve method is the most common way for China’s water—flood fields to predict their development index. These studies provided the classification, correlation and evaluation of more than 20 kinds of water displacement curve analysis methods and draw the various types of water displacement curves of FD33 oilfield. Through the analysis of nine common water displacement curves of FD33 oilfield, we predicted the development indexes of the oilfield and selected the first water displacement curve prediction results as the final prediction. The prediction of water drive reserves was 2419.35×104t, recoverable reserves was 943.9×104t, water displacement recovery was 39.1%. Summarized the characteristics of water rising of FD33 oilfield. And water rising mechanisms on the influencing factors are analyzed. Finally put forward some water control measures Key words: water cut ;degree of reservoir recovery ; water displacement curve；dynamic prediction 目 录 TOC \o 1-3 \
