Evaluation of tapping measures is an important means to explore the reservoir development.The producing blocks of peripheral Changyuan has stepped into the high water cut stage,where plane and inter layers have obvious contradiction,so tapping measures are adj usted in some blocks.To evaluate the tapping techniques in Longhupao Sapu reservoir,we established a multi-factor fuzzy evaluation method by checking and assessing the water flooding control degree, reserves producing degree, formation energy maintaining level, production rate of remaining recoverable reserves, annual oil production comprehensive decline rate, water escalating rate and utilization rate of oil and water wells.It is found that Longhupao Sapu reservoir evaluation results were “better”after the adj ustment,and the results are consistent with the actual situation.The Multi-factor fuzzy evaluation method can accurately determine the effect of tapping measures,which is a simple,accurate and reliable scientific method.%挖潜措施效果评价是分析油藏开发的重要方法，长垣外围已开发区块进入中高含水开发阶段，平面及层间矛盾突出，部分区块进行了挖潜措施调整。以龙虎泡油田萨葡油层为例，通过多因素注水开发效果模糊评判法对水驱控制程度、储量动用程度、能量保持水平、剩余可采储量采油速度、年产油综合递减率、含水上升率和油水井利用率7个因素进行综合评判，评价水驱挖潜措施效果。结果表明：龙虎泡油田萨葡油层通过措施调整后的综合评价结果属于“好”，与实际情况相符。多因素注水开发效果模糊评判法能够准确地确定低渗透油田挖潜措施效果好坏，可以作为低渗透油田挖潜措施效果的评价方法。
