摘要(Abstract)：

断层附近局部富集的剩余油是特高含水老油田重要的挖潜方向。以大庆长垣油田为例,紧密围绕断层边部剩余油精准挖潜的开发需求,创新了以"井断点引导"三维互动断层精细解释为特色的井震结合构造表征技术,准确刻画了断层三维空间形态,深化了断层边部剩余潜力的认识,转变了断层附近井位部署和挖潜调整的思路,形成了老油田断层附近剩余潜力区优选方法及配套的挖潜措施,有效挖掘了高含水老油田断层遮挡形成的剩余油,取得了显著的增储增油效果。
Tapping the remained oil potential in the vicinity of the faults is the important direction for extra-high-watercut oilfields. Taking Daqing Placanticline Oilfields as an example, aiming at the precise development demand of the remained oil, the characterizing technique was innovated for the structures by the well-seismic combination featured by "guided by the well breakpoints" 3 D fine description of the faults, so the 3 D spatial configuraton of the faults have been accurately described, the understanding of the remained oil potential near the faults fault has been deepened, the thinking of the well location arrangement and tapping adjustment has been transformed, the tapping measures of optimizing method of the potential block near the faults and matching tapping measure have achieved for the mature oilfields, so the remained oil resulted from the fault barrier of the high-watercut oil fields has effectively tapped and the obvious effects of enhancing the reserves and oil production have been obtained.
