摘　　要：平衡剖面技术近十几年已成为油气勘探的一项基本技术。平衡剖面正演模拟可以迅速、有效地检验一种假设，为解释人民提供合理的模型。同时正演模拟可以动态地显示构造变形历史，为研究油所的形成演化提供依据。对塔里木盆地实际剖面的模拟表明，盆地内不同层次的滑脱构造在变形中起着重要作用，利用断弯褶皱模型及双重构造模型可以更合理地解释某些油气圈闭的成因。Balanced cross section has become a basic technique for hydrocarbon exploration. The forward modelling of balanced cross section can check the hypothesis rapidly and effectively and give out a reasonable model for interpretation. It can also demonstrate the deformation history dynamically and provide evidence for the research of formation and evolution of hydrocarbon. The modelling examples in Tarim Basin indicate that detachments are the majar factor controlling the deformation. The models of fault-bending folds and duplex derived from forward modelling can reasonably explain the origin of oil gas traps, especially in foreland fold-thrust belt.
