摘　　要：在松辽盆地萨南开发区已进入特高含水开发阶段,剩余油挖潜难度越来越大情况下,断层边部剩余油潜力已成为目前调整挖潜主要对象之一。根据文献检索结合断层边部井钻遇断点情况,总结出正断层破碎带在测井曲线显示规律,研究出补划测井解释厚度图版,建立适合本区断层破碎带宽度与断距定量关系,为断层边部挖潜提供了地质依据。将成果应用在受断层碎带影响测井曲线异常井段厚度解释、断层边部挖潜井设计及断层边部压裂井工程设计上,取得好的效果。Under the circumstance that the Sanan Development Zone in Songliao Basin has entered the stage of ultra-high water content development,and the remaining oil potential of the remaining oil has become more and more difficult to tap,the residual oil potential of the fault edge has become one of the main objects of adjustment and mining.According to the literature search combined with the fracture point of drilling in the fault edge well,the display law of the positive fault fracture zone in the logging curve is summarized,the thickness map of the supplementary logging interpretation is studied,and the quantitative relationship between the width and the fault distance suitable for the fault fracture zone in this area is established,which provides a geological basis for the potential excavation of the fault edge.The results are applied to the thickness interpretation of the abnormal well section of the logging curve affected by the fracture fragmentation,the design of the excavated submerged well at the edge of the fault and the engineering design of the fracture edge fracturing well,and good results are achieved.
