摘　　要：对于注水开发的非均质砂岩油田,只有搞清注采井网的完善程度和剩余油的分布状况,才能有针对性地采取挖潜措施,提高油田开发水平。针对喇萨杏油田非均质严重、开发时间长、含水率高的特点,首先在检查井资料分析的基础上,明确了影响特高含水期剩余油形式的两大主要因素;其次以精细地质研究和渗流理论为基础,提出了基于井间非均质性的注采关系定量评价方法;最后将注采关系与剩余油评价结果相结合,发展了特高含水期的10类剩余油潜力类型和4种调整潜力的快速评价方法。提出的方法具有操作简便、人为影响少的优点,可广泛应用于水驱砂岩油田的剩余油潜力类型及挖潜措施的研究。S开发区B1区块的评价表明,特高含水期以零散的注采不完善型剩余油为主,挖潜措施主要是堵水和压裂,现场实施取得明显的增油降水效果。In allusion the characteristics of serious heterogeneity,long development interval and high water cut,on the basis of well data analysis,2major factors which influenced remaining oil development were clarified in Lasaxing Oilfield.Based on fine geological study and filtration theory,a method for quantitative evaluating the relation between waterflooding and production was proposed based on interwell heterogeneity.The injection-production relationship was combined with the remainingoil evaluating result,10 types of remaining oil of potential taping and 4methods for evaluation were developed.The proposed methods are easy for operation with less human influence,it can be used for taping the potential of remaining oil in waterflooded sandstone reservoirs and for studying measures of potential taping.The result of evaluation in Block B1 of S Development Area indicates that there exists mainly scatteredly distributed remaining oil at extra-high water stage,the potential taping mainly includes water plugging and fracturing,field application obtains evident effects of oil increment and water reduction.
