摘要(Abstract)：

AFT是一种寻找采油井内可动剩余油的新技术。采用测井电缆将分层测压取样仪送至井下,通过一对可调控封隔器实现测试不同厚度的单个目的层或层段,利用自排液泵抽取地层内原状流体样品,录取目的层或层段系列压力资料,得到分层储能参数和可动剩余油信息。油田应用结果表明:在多层合采的高含水油井中,利用该技术可找到数量可观的潜力油层;根据AFT测试结果有针对性地采取堵/隔水措施,增油降水效果显著。AFT技术为高含水油井精准找剩余油、精细挖潜提供了有效手段。
AFT is the new technique which can be used to find out the movable remained oil in the producing wells. With the help of the logging cable,the separate-layer pressure-testing and sampling tool is conveyed into the borehole,by means of the a pair of adjustable packers,the individual target and interval with different thicknesses can be tested,and moreover by using the self-drain out pump,the original formation fluids can be extracted,the series pressure data of the interesting layers or intervals section and moreover the energy storage parameters and movable remained oil information can be achieved; according to the AFT tested results,the corresponding water plugging/block stimulation was applied,the effects of the oil increment and water drop were obvious. The AFT technique is the effective countermeasure for the precise remained oil seeking and potential tapping of the oil wells with high water cut.
