摘　　要：大庆油田杏南开发区进入特高含水期,油层非均质性严重,控水挖潜措施效果变差。统计杏X示范区544井次注、产剖面资料,分析424井次油水井措施,形成了一套水驱精细挖潜调整思路。研究结果发现,监测资料可以评价油井转注、油水井补孔,水井细分、调剖、酸化、测调,以及油水井对应压裂等措施效果,评价油水井动用状况;利用注、产剖面对应测试资料,能够发现低含水层及低含水方向潜力层;调整注采系统及注采结构,指导特高含水期水驱控递减、控含水措施。监测资料对试验区开发调整各阶段措施的适应性分析,可为特高含水期水驱精细挖潜和高效开发提供有力依据和成功经验。Xingnan development zone of Daqing Oilfield has entered extremely high water cut stage,with serious reservoir heterogeneity and poor effect of water control and potential tapping measures.A set of ideas for fine potential tapping and adjustment of water flooding was formed by going over the injection and production profile data of 544 wells in Xing X demonstration area and analyzing the oil and water well measures of 424 wells.The results show that the monitoring data can evaluate the effect of measures such as converting production well to injection well,remedial perforation of oil and water well,water well subdivision,profile control,acidification,adjustment of testing,and oil and water well fracturing can be evaluated so as to evaluate the production status of oil and water wells.The low water content and potential layers with low water content can be found based on the corresponding testing data of injection and production profiles,thus adjustment of injection-production system and injection-production structure can guide water drive control decline and water cut control measures in ultra-high water cut stage.The adaptability analysis of monitoring data to various stages of development adjustment measures in the test area can provide strong basis and successful experience for fine tapping potential and efficient development of water flooding in ultra-high water cut period.
